Ren Amaki

Ren was a high school student before he he failed to save his childhood friend in his old world and was instead killed in the process of her rescue. Ren initially mistook the world he was summoned to to be exactly like the VRMMO game from his world "Brave Star Online" where Level came first and Status Boosts second in priority making his strengthening method extremely inefficient also leading to the collapse of his party. He acts like cool loner but he really does care for his comrades. However, he doesn't get close to them because he is terrible at team play. He carelessly killed a dragon which caused a plague as well as other problems. He is the youngest hero.

Personality
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 alone. His particular attitude to this 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 stubornly refuses to think otherwise. Unlike Motoyasu and Itsuki, Ren also seems to actually recognise 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 gave a proposal to help resolve the situation 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 crying Naofumi.

After his party was slaughtered by his, Itsuki and Motoyasu's, act of releasing the Spirit Turtle, his personality ends up taking a significant blow. His confidence has noticably declined, and he has begun to realise that the world isn't a game and that his comrades are in fact dead and not coming back. To escape his guilt over this, Ren tries to blame them, stating they were too weak and got killed, something Naofumi and Eclaire both believe is a sign of his selfishness. He breaks further when Naofumi calls him out on this and also blocks his attack, he winds up calling it a cheat that the Shield is so powerful and runs off in anger. Later, due to his destrught state, he was easily manipulated by Malty, who gave him false words of comfort that he desperately needed to here. He wound up stripped of his belongings by her, abandoned and finally snapped completely, succombing to the Curses of Greed and Gluttony.

While possessed by greed, Ren becomes a bandit leader and organises 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 succombing to Gluttony he gets much worse, and 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 Eclaire and try to save the world his late comrades loved so much. He also becomes steadily more open, though he is still rather timid compared to before and no longer puts up any elements of false confidence or a cool facade, he even notes outright that he wants to get to know the other heroes and get along with them from now on. He is no longer obsessed with power, and diligently began studying under Naofumi to learn the world's language. He has also resolved to help out the village any way he can and asked Naofumi to be given a job there. Finally, he has expressed regret over his past actions, especially when learning that the dragon he killed was acting as an adoptive father to one of the girls in Naofumi's village, Wyndia, who became a slave as a result of said dragon's death. After appologising to Wyndia, and being slapped and told off for his trouble, he has began to interact with her roughly as frequently as Eclaire, and is implied to have feelings for both of them.
