My companions died trying to bring peace to this world. I want to fight to make sure they didn't die in vain.

—Ren, Volume 11, Epilogue

Ren Amaki (天木錬 Amaki Ren?) is the Sword Hero (剣の勇者 Ken no Yuusha?), one of the four holy heroes summoned in Melromarc.


Ren is a person who acts cool and tries very hard to portray a loner's image. He runs his party like a guild, only working with the other members when the prey he seeks to kill is too strong for him to hunt alone. His attitude towards his comrades is that weaker members should work to individually increase their powers to catch up to the stronger ones.

Like the other heroes, Naofumi excluded, he is initially under the impression that the world they've come into is a game, and he stubbornly refuses to think otherwise. Unlike Motoyasu and Itsuki, Ren seems to actually recognize to some extent the consequences of his actions, as he understood it was his fault the Zombie Dragon caused a plague. He is also more reasonable than Itsuki or Motoyasu, as he believed in the possibility that Naofumi was telling the truth when he claimed that Princess Melty was under his protection and not his hostage, and tried to propose an idea that would help the situation resolve peacefully. He, alongside Itsuki, also stood up for Naofumi after Malty and Motoyasu tried to take Raphtalia from him via cheating, and called Motoyasu out for believing Raphtalia was brainwashed even when they saw her comforting an obviously deeply upset Naofumi.


Ren has a black hair with a pretty handsome face and was described by Naofumi to be really suited to be a protagonist of dimensional-cross stories from manga or anime bishounen. He always dresses in black or some other dark color.

Ren comes from an Alternative Japan. In the world he lives in everything is much more advanced and futuristic. In his world, every game in the modern era is run on VRMMO.

One day while on the way home from school, Ren was caught up in a murder case. The murder case was pretty well known around the town he lived in. Ren mentioned how he remembers saving his best friend and how the criminal arrested. Ren didn't go into too much detail after that but started rubbing his side when talking, it was suspected that Ren was probably stabbed on the side of his body during the struggle then later died from blood loss.

Before he knew it he woke up he found himself summoned to another world. The world reminded him a lot of the VRMMO he played in the previous world, Brave Star Online.


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.

Though when Naofumi lost the duel against Motoyasu, Ren and Itsuki were the ones to call out Myne for her illegal interference in the duel and announced that Motoyasu was the loser.

Volume 2

He carelessly killed a dragon which caused a plague as well as other problems.

Volume 5

Ren initially made the mistake of thinking that the world he was summoned to was exactly like the VRMMO game from his world "Brave Star Online" where Level matters more than Status Boosts which made his strengthening method extremely inefficient this also led to the collapse of his party.

Volume 11

While possessed by greed, Ren becomes a bandit chief and organizes them to amass wealth, he also defeats people on the road and steals their stuff, but fortunately doesn't kill them. He becomes obsessed with increasing his power. After succumbing to Gluttony this gets much worse, and he is willing to kill people to absorb EXP from them and grow stronger. His obsession with power is however either hollow or just an attempt to escape from reality, as when asked the reason for it he can only express the purpose given to him by others: saving the world. When he is finally defeated, he reverts to a broken, but otherwise normal, Ren.

After being freed from his curses, Ren decides to learn under Eclair and try to save the world his late comrades loved so much.

Vassal Wielders



  • The four legendary heroes Naofumi, Ren, Motoyasu and Itsuki are all inspired by the protagonist of series the author has read before in the past.
  • Ren's character is based off the Isekai, loner and sword wielder trope. Ren is an obvious parody of Kirito from Sword Art Online (who share the same voice actor)
  • Ren comes from an Alternative Japan where VRMMO exist. He believes that the world he was summoned to his based off the game Brave Star Online is played in the previous world
  • He treats his party members as NPC and uses them to grind in an appropriate leveling ground in accordance with their levels and will join hands only when needed.
