Motoyasu Kitamura/Chronology

Volume 1
Motoyasu is the Spear 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, Motoyasu pretends that he doesn't care about being summoned to another world. Motoyasu doesn't particularly think much of the other heroes and rather invest his time in chasing and flirting with women.

Because of his gullibility, he was easily deceived by Myne and tricked into helping her accused Naofumi of a false crime he never committed and causing Naofumi to be outcast as a criminal.

He was once again deceived by Myne and confronted Naofumi after hearing that Raphtalia was his slave. He forced Naofumi in a one-sided duel and only won because of Myne's interference which he was unaware of. After Raphtalia's curse mark was removed, he was shocked by the fact that Raphtalia had slapped him and yelled at him angrily before going back to Naofumi to comfort him. Ren and Itsuki later pointed out to Motoyasu that someone had interfered with the duel and announced Motoyasu as the loser. Motoyasu couldn't believe his eyes and claimed Raphtalia was brainwashed, which the other heroes were amazed that he could say that after seeing Raphtalia lovingly embrace Naofumi.

Volume 2
Motoyasu was given the largest of the rewards and praise from the king. When Naofumi was denied his promised allowance, Motoyasu says that Naofumi wasn't anywhere nearby at the time of fighting the wave. Itsuki and Ren joined in supporting Naofumi about the unfair duel which prompted Motoyasu to shout that he didn't lose.

Later, Motoyasu was named Governor of the wave-affected village of Riyute. Malty levied a tax of 50 silver coins for entry or exit of the village on his behalf. Motoyasu was baffled by the protest of the villagers, for he had really no grasp of the value of the money demanded. After realizing the grim situation, Motoyasu asked Malty to reconsider but she wasn't lending her ear. Due to circumstances, the Governorship of the village was depended on an unreasonable duel between Naofumi and Motoyasu. Motoyasu was confident of his victory and started laughing at Filo, who retaliated by kicking him in the crotch, much to Naofumi's delight and enthusiasm for the race. Not noticing any foul play, Motoyasu raced but was defeated. As promised, the ownership remained with the previous Governor.

He once delivered a sealed "miracle seed" to a village in the south to save them from famine. Though his game knowledge helped him at that instant, it didn't go exactly as he promised the villagers it would. As it turns out, the seed actually was the seed of a giant monstrous plant which caused a lot of damage to the village after he left, as Naofumi pointed out the seed must have been sealed away for a reason and found the inscription matched his assumption. Motoyasu didn't know about his failure and continued to believe he did a great deed for the village.

Volume 3
Motoyasu was completely blind to all of Malty's unreasonable spending. After seeing Filo in her human form, he charged at Naofumi for her freedom, and also to demand that Naofumi's monster bird be killed, as it always kicked him in the crotch. After realizing that Filo and the bird are one and the same, he was petrified but was kicked away by Filo.

When the Cult of Three Heroes claimed that Naofumi had a brainwashing shield and that he kidnapped the second princess, Motoyasu completely believed the claim. He didn't notice Malty's attempt to kill Melty, while the other heroes did and began to suspect that things were not quite how they appeared to be. Motoyasu puts all his effort into hunting down Naofumi, in a way favoring Malty and the Church of the Three Heroes. Naofumi feels that Motoyasu's efforts to free Filo from his control, might be more about wanting to claim her for himself because the former said that he "digs moe angels" and his suspicions are all but confirmed when, during the time when the three heroes are trying to rescue Melty from Naofumi's "kidnapping", Motoyasu attaches a chain to Filo's leg that takes away her powers so Motoyasu can claim her for himself.

Volume 4
Convinced of Naofumi's guiltiness, Motoyasu and his party keep chasing down the Shield Hero's group across the mountains all the way to Van Reichnott's territory. Nevertheless, he ended up losing their tracks when Raphtalia's illusion magic and Filo's false trail lead his group in the wrong direction. Unknown to him, tired of chasing her sister and Naofumi, Malty started a fire in the woods to smoke out her prey. Later, he was told or assumed that Naofumi was the one behind the forest fire.

Days later, he encounters with the Shield Hero again, after Naofumi met Fitoria, and unlike the last time, Naofumi tried to make peace with Motoyasu, but the Spear Hero showed more determination than ever to kill him. He has been fed false information by the church's shadows and believed the story of Naofumi's killing of the other two heroes so he decided to avenge them. After the fierce battle, he tried to give his all in the hope of freeing Melty, Raphtalia, and Filo from Naofumi's supposed brainwashing power. Finally, after realizing that he was fighting the wrong person, he joined forces with the other heroes in fighting the true culprit: the High Priest.

Volume 5
During the meeting to share information with the Queen and the 3 other heroes. He told of his Power up methods, which was Enhancement Method where the user can use items and monster drops to imbue the weapon they wield.

Volume 6
Days after the end of the Wave Battle on the ocean and the battle of Naofumi's party against Glass, L'arc and Therese, the heroes were reunited by the Queen to discuss about the new threat.

Volume 7
(Information to be added later)

Volume 10
Upon Naofumi's return from Glass World and his reunion with Queen Mirella, it is revealed that Motoyasu, Ren, and Itsuki are missing again. After Eclair and the Hengen Muso Master took them out of the Spirit Turtle, the castle doctors took care of them and cured their weakened state, nevertheless, the heroes remained unconscious. A week before Naofumi's return, Motoyasu and the other heroes woke up and learned of their defeat and captivity at the hands of Kyo and the fact that they were rescued by Naofumi. The realization of their failure shocked them greatly and shortly after they escaped from the castle using their teleportation skills.

Volume 11
Weeks after the events of the Spirit Tortoise incident, Motoyasu finally caught the ear of one of his companions, Elena, looking after her family store. Motoyasu rushed to her side and, to his surprise, learned that Elena was tired of adventuring and now wanted to keep a low profile, living a nice comfortable life despite it being boring. When Naofumi came to talk to him, Motoyasu was shocked and confused, so he used the Portal Spear to escape from Naofumi before hearing him out.

Motoyasu also managed to find Malty along with Lesty. But to his shock they were with the Sword Hero Ren, Malty was feeding lies to Ren and deceiving him and used the Sword Hero to escape from both Motoyasu and Naofumi. In the end, Motoyasu finally realized how much of a fool he was to believe in Malty and fell into depression, not knowing that these events had caused his Legendary Spear to unlock the Curse Series.

Betrayed and disowned by his former companions, Motoyasu had lost all motivation. Naofumi tried to cheer him up by bringing him to a bar, but Motoyasu had neither the will or the strength to resist and let him do as he pleased. Because Naofumi had no idea how to cheer him up, Filo took on the challenge of trying to cheer him up, after multiple attempts, Motoyasu finally broke out in tears and held his face to Filo's chest sobbing. Thus began his deranged love obsession for Filo.

After the events at the bar, his curse series seems to kick into effect. As a result of his curse series, he could now only see women as pigs and can only hear "oink" when they talk, except for Filo. He started stalking Filo and calling Naofumi his "Father."

Motoyasu took Naofumi's advice and used the Power Up Method Naofumi mentioned to him, as a result, he ended up becoming the strongest Legendary Hero out of the 4 heroes. He was later found running away with Filo's carriage with 3 other Filolials. Saying his farewells to Naofumi and Filo.
