Ren Amaki/Chronology

Volume 1
Ren is the Sword Hero one of the Four Legendary Heroes summoned from another world. He was summoned along with the three other Legendary Heroes in Melromarc. Like two of the other heroes, Ren also pretends that he doesn't care about being summoned to another world and thinks that he is better than the rest of the Heroes.

When Naofumi was falsely accused of a crime he never committed. Like the rest of the heroes, he believed that Naofumi was guilty and even used the situation to make himself look better in the eyes of others.

Later Ren, Motoyasu, and Itsuki fought the second Wave's boss the Chimera and took one of its heads for his weapon. Later when Naofumi lost the duel against Motoyasu, Ren, and Itsuki were the ones to call out Malty for her illegal interference in the duel and announced that Motoyasu was the loser.

Volume 2
Ren and his party was hired to kill a Dragon living in the mountain next to the East Village and then left the corpse as a tourist attraction and source of economy for the village that hired him.

Volume 3
Though he wasn't aware of it at first Ren later learned that the dragon's rotting corpse mutated a hoard of monsters into poison types, created a plague that afflicted the village that hired him, and eventually turning into a Zombie Dragon that severely injured Raphtalia in the process of putting it down. A guilty Ren runs off to the village to confirm Naofumi's story.

During the Third Wave, Ren jumped onto the Ghost ship and, still following his game knowledge, fought the Skull captain trying to make it spawn the Soul Eater. Fighting the undead for three hours straight Naofumi arrives on the ship and uses Raphtalia's magic to force the Soul Eater out of hiding. Ren soon discovers that his attacks are too weak to hurt the Soul Eater and can only watch as Naofumi defeats the boss using the Iron Maiden.

Following the Soul Eater's defeat, the group is almost attacked by another of the monsters, only for it to be one hit killed by Glass who similarly takes Ren down. The only reason Ren survives the encounter is that Glass was only interested in killing 'actual heroes' and not someone who was clearly too weak to call themselves one.

Later on, after he has recovered Ren is informed by The Church of the Three Heroes that Naofumi has kidnapped Melty Q Melromarc and killed her escorts and naturally goes off to confront Naofumi. Although at first reasonable with Naofumi and the rest of his associates Malty walks in with the claim that Naofumi's recent surge in popularity is due to unlocking a brainwashing shield, with a fearful Melty refusing to return with them seeming to confirm her claims.

With negotiations having broken down Ren attempts to incapacitate Naofumi, though the use of his Iron Maiden buys enough time to escape with his party.

Volume 4
Ren's party, along with Itsuki's party, are nearly killed by the Church of the Three Heroes for their incompetence but are saved by the Shadows. They join with Naofumi's and Motoyasu's parties as they were under attack by the High Priest and The Church of the Three Heroes, using powerful skills in a sneak attack that initially broke through the High Priest's sanctuary power. The Other three heroes and their companions combine all their power in a single attack that fails to break through the enemy, not even triggering the Wrath Shield's cursed flames in the middle of the enemy formation managed to break the enemy.

Finally, Naofumi calls everyone close to him, remembering and focusing on how much he hated the other heroes and Malty and evolved Wrath Shield into its next stage and unlocked a new attack with it. Ren and the others create an opening through the Priests sanctuary, allowing Naofumi to use the new attack, Blutopher, and kills the High priest with a brutal attack that leaves him comatose for three days.

Ren and the other heroes and companions stayed with the Queen until Naofumi was safe to transport again, at which point in time the Queen takes them back to the castle where she humiliates and beats down the king re-establishing her authority in the process. She then explains that Malty's and the King's actions have left her country in a precarious situation with their fellow countries and thus are receiving punishment.

Onto business, the Queen asks Naofumi to marry her youngest Daughter Melty. Basically Naofumi, as the shield hero, is worshiped as a god by Melromark's enemy Siltvelt, if he were to marry into their family it would pacify the people of Siltvelt who are up in arms about how Naofumi has been treated. Had Malty made an effort to put Naofumi under her thumb the throne would have been as good as hers, as it stands now the Queen must now force a Slave Seal on her just to wrestle the truth out of her.

Though Ren and the others try to stop them Naofumi and the soldiers stop them as a confession is forcibly wrung out of Malty, and shortly thereafter confirmed further when Motoyasu takes Malty as a slave as well. After a while Ren and Itsuki came to understand the truth about Malty, and that he was wrong about Naofumi. Ren also received some satisfaction as while he and Itsuki weren't treated badly Motoyasu did receive a lot of preferential treatment over them.

That said they were shocked to witness the interactions between Naofumi and the Queen as they calmly discussed torture methods to use on the recently disowned King and Princess ranging from execution to training them to become domestic servants. Eventually, Naofumi settles on renaming Aultcray to Trash and Malty to Bitch and her alias of Mein to Whore, Ren and Itsuki eventually agree that though it's somewhat offensive to their tastes the punishments are somewhat appropriate before they go off to their rooms for the night.

Volume 5
The day after the Queen's return Ren and Itsuki joined Naofumi at a banquet in Naofumi's honor. The Queen made an announcement to the gathered guests that the Cal Mira Archipelago had become active making Ren excited in the process. It is explained that the islands have a once in a decade activation period that causes the experience gained from killing monsters to double.

Because of this the heroes and their companions should be able to use this opportunity to reach level eighty with a measure of ease getting Ren all excited. However before that, the Queen pulls aside the heroes for a meeting: basically, in order to increase their fighting power, it is important that the four agree on a plan of attack in advance of the waves, making the army a part of their parties like what Naofumi did during the last wave for example.

As a start, while waiting for Motoyasu to show up Ren, Naofumi and Itsuki introduce themselves to each other's parties. Ren and Naofumi develop a low opinion of Itsuki's party who talk down to them, treat the newest member of their party, Rishia Ivyred, as a common servant or slave, and gives an overall arrogant atmosphere. They're also insulted by the implication that Itsuki has been doing more work than the other heroes.

Ren's party treats the other two heroes with more respect, in particular, they apologize to Naofumi for how they treated him when they first met: with the king the way he was they all had reason to fear what the king would do to them had they joined his party. However, Ren receives criticism from both Naofumi and Itsuki for treating them like members of a guild, having them level independently of him and collect bits and pieces of monsters for him.

Finally, the time comes to introduce Filo and Raphtalia. Ren openly insults the pair suggesting that they would hold him back in a fight, though he ultimately recants his statement perhaps remembering the fight during the third wave. That said they show Naofumi an awkward glance for not treating them as NPC's or slaves. That said they do take the opportunity to confirm that they're not being forced to fight for Naofumi. That said they do apologize for mistaking their relationship prior to the duel with Motoyasu.

Motoyasu eventually arrives at the meeting after a confession has been wrung out of Bitch for trying to poison Naofumi. Onto business Ren, Motoyasu and Itsuki have knowledge about their weapons that Naofumi doesn't have access to. Likewise based on the power he demonstrated while fighting the Soul Eater, Glass and the High Priest Naofumi has somehow acquired fighting power that the others can't compare to. In fact, Ren and the others are so weak compared to Naofumi that she and the other country representatives are afraid for their lives if they keep fighting in the waves.

Therefore the Queen is holding the meeting for the purpose of exchanging information on how to make one another stronger. Ren and the others initially want to hear from Naofumi first, specifically what he fed to his shield to unlock the Wrath Series believing that they would be unstoppable if they had that much offensive power, and they also want to know how he was able to give Filo and Raphtalia so much brute strength.

Naofumi, however, has one condition for giving up such valuable information: he wants to hear from the others first. When they first came to this world they all had advanced knowledge on both it and their weapons, they also sat Naofumi down and called him a weakling to his face. Then they refused to help him in any way after his rape accusation while they received the full support of the kingdom.

From Naofumi's standpoint wanting to be on equal footing with the others is only natural. Sadly it soon becomes apparent that the others still believe that they're in a game, they've already dismissed the last wave as being a event battle: one that they were supposed to lose for story purposes, and that Naofumi's success in defeating Glass and the Soul Eater can simply be chalked up to the game-breaking power he unlocked.

Increasing the concern for them they also believe that they're immortal: even if they are beaten down until they are an inch from death they will simply be revived at the nearest hospital no worst for wear, the reason why they seriously tried to kill Naofumi is because they thought that only heroes can kill other heroes. An exasperated Naofumi states it's a miracle they're still alive, a fact they somewhat agree with as they believe they have 'divine protection.'

Before moving onto actually useful information Naofumi employs psychological warfare to make sure they don't lie to him. Aside from information that Naofumi already knew Ren and the others reveal that the legendary weapons have the ability to copy other weapons that they pick up that belongs to the same class as their legendary weapons, a fact they discovered when they like Naofumi tried to buy better weapons in Melromark's weapon shops, the difference being that they had picked up weapons that were the same as their Legendary weapons.

They also reveal that the legendary weapons have the ability to transform the monsters they kill into drops: weapons, armors, and tools for them and their companions to use. Also if the necessary ingredients are fed to their weapons they can be set to automatically produce potions and other items for them. They also offer to make up a chart where Naofumi can get good exp and materials for his weapon. However, they disagree on the method for strengthening each individual weapon that their Legendary weapons can transform into.

Itsuki maintains that a weapon's power is tied to its rarity, it's power can be increased by feeding it specific ores. Ren maintains that Proficiency is what's important in a weapon, the longer you use it the stronger it gets until it's reached it's maxed level, and if you have no intention to use it again then you can safely transfer that mastery to a more useful weapon to increase its proficiency. Motoyasu states that you can draw magical power out of objects and use it to give unique effects to weapons through refinement.

As their information doesn't line up the trio accuses one another of lying, even worst they then direct the frustration that they've built up by accusing one another of lying at Naofumi accusing him of gaining a god's favor to increase his and his companions' power. Naofumi maintains that it's not someone else's power: he unlocked Slave, Beast and Filolial user shields that gives a bonus stat growth with every level up for his companions.

He also explains the effect that Filo's cowlick feather that they got from Fitoria during the class up. When Naofumi mentioned Fitoria's transport ability the others mentioned that they unlocked a transport weapon from feeding sand from the Red Dragon Hourglass to their weapons. Back to the topic of Fitoria Naofumi also warns them that Fitoria would hunt down and kill them if they don't start cooperating with one another to fight the waves.

Once again dismissing Naofumi's warning the others accuse him of getting help from a god again to unlock the Wrath Shield. Naofumi once again states that he has not met this world's god, and even if he did he would not have this amicable relationship the others have imagined. To clarify Naofumi believes that he unlocked the Shield of Wrath from his deep, festering hatred of this world and the other heroes, furthermore his help menu has informed him that the Wrath Shield is a cursed weapon and that he should not use it in spite of the power it has.

Sadly a quick glance through his own help menu reveals nothing to Ren which in turn causes the group to revert back to accusing one another of lying and Naofumi of cheating with vulgar insults being thrown in. The meeting is called short as a group of soldiers barge in informing them that the Heroes companions have gotten into an argument with one another.

The Heroes go to calm their associates down as the meeting and the party is officially called to an end with the understanding that another meeting would be held in the near future. Ren and the other heroes receive a message from the Queen detailing the fruits of Naofumi's experiments: All the heroes reinforcement methods work, using them all in combination will dramatically increase their fighting power, they just have to believe in one another.

Instead, a frustrated Ren orders his party to shop for items for the trip while he loads himself onto the ship for Cal Mira and along with the other Heroes, they forcibly take the captain's quarters and the Luxury room reserved for Naofumi but are forced to wait for the Queen to let them go. Their greed backfires on them however when the extremely rough waters on their way to the island and the large open space cause them to become both seasick and injured.

Arriving on the island the heroes and their companions are roped into a tour around the main island, in the process, they learn that Cal Mira is apparently sacred training ground for the Heroes, and as such their predecessors have left behind monuments for them detailing magic for them to use. However, Ren and the others dismiss the information on the plaque because they can't read what it says.

However, they're surprised when Naofumi is able to read the plaque and shocked when he used a powerful stat boost spell to increase Filo's stats. None the less they decide to get weapons that allow them to learn the magic written on the plaque like they believe Naofumi has done already. The next day Ren and the others proceed to rampage through the explosion of monsters that have been born as a result of the increase in exp though he did struggle quite a bit.

After a couple of days at the Archipegalo Ren and the other heroes break in the main island's hot springs where they end up being dragged into Motoyasu's perversion as they discuss among the various female members of their parties who their preferred type was, and on peeking on the girls in the next bath over. Eventually, after five or six days on the Island, Naofumi comes to the other Heroes with a bit of bad news.

Filo has discovered a Dragon Hour Glass in a temple at the bottom of the ocean off the coast of Cal Mira, worst yet it's almost empty meaning that a wave is about to happen at Cal Mira. While they are dubious about Naofumi's story Itsuki and Motoyasu are chomping at the bit to put their new high-level parties to use only Ren is unwilling to fight the wave. Eventually, the other Heroes figure out that Ren is Aquaphobic and test their theory by chucking Ren into the water at the beach. He nearly drowns in waist deep water.

Naofumi offers the other Heroes the use of the Pekkle Kigurumi that will allow them to transform into giant Karma Penguins and swim down to the temple with ease though they politely decline instead using scuba diving type magic prepared by the resort. On their way back from the temple Ren ends up using the costume to swim back to sure and is quite overjoyed to be able to swim at long last. With little time before the wave, Naofumi sits the others down and talks to them about what they are planning to do during the wave.

Specifically, Naofumi wants to recruit Melromark's army into their parties, aside from the troops they will also get Melromark's navy on their side as well, providing boats and platforms they can fight on he also wants to recruit a large number of adventurers as well. The Logic is that most of the people there are using the activation event to farm for exp: between that, the powerful monsters guaranteed to come with a wave, and the exp bonus from the Heroes weapons they should get a lot of volunteers.

Thus while Naofumi goes back to the castle to recruit the Queen and the Soldiers the other three heroes run around the island collecting as many adventurers as possible. When the Wave does come Ren isn't very useful, only able to take shots at the wave's boss the Inter-Dimensional Whale when it surfaces to attack the ships. He is stunned to witness L'Arc Berg and Therese Alexanderite take out the boss almost single-handedly, shortly before the otherworldly hero knocks all of them out.
