YMMV / Psyren

• Alternative Character Interpretation: Is Amagi Miroku an Omnicidal Maniac, or has his past led him to fear humanity so much that he simply wants it to stop existing?
• Complete Monster: In this series about people who time travel to a hellish futuristic dystopia to prevent a disaster, these three manage to stand out in their depravity:
  • Mithra is a mysterious woman who is revealed to be the engineer of several misfortunes in the series. Originally a human, she contacted an Eldritch Abomination known as Quat Nevas and becomes a vessel of it. To bring down Quat Nevas to Earth, Mithra then manipulates one of the psychic child that was horribly experimented by the government, Miroku Amagi, by giving him a dream of a sheep and a wolf and lies to him and his friends about the meteor that would grant them a great power, under the pretense that Mithra will guide Miroku to create his perfect world. After becoming a higher member of an organization that Miroku established known as WISE, it was also revealed that Mithra creates a core that could turn human beings into monstrous beings known as Tavoos. When said organization kidnaps the members of the resistance organization known as Root, Mithra takes an interest on one of the Root members because she has an interesting body that she wants to take over. When Miroku tries to make a new human race by using his ultimate power, Mithra backstabs him, sneering that a sheep can never become a wolf and sheep should remain as the sheep they are, before proceeding to merge with Quat Nevas and letting it consume the Earth. Manipulative and fanatical, Mithra will stop at nothing to cause destruction and misery to serve the master that she worships.
  • Usui is an eyepatch-wearing man who starts off as a fake cop trying to steal Ageha's Psyren Calling Card. However, as time went by, he becomes something worse. Establishing his totalitarian Amakusa Empire in the future by disguising himself as a reincarnation of Shiro Amakusa, it was revealed that Usui had a penchant for executing people solely for entertainment, secretly laughing at the ignorant masses. It was also revealed that in flashback, he murders and mind-wipes some of the candidates that try to participate in the Psyren Games in order to obtain the Calling Cards. When Usui tries to kill the person who created the Psyren Games and one of Ageha's companions tries to stop Usui, he then mind-wipes her memory. Even after being defeated, Usui just sneers towards one of his subordinates by saying that they live in a world where farces prevail.
  • Aoi Yusaka is a young man who is revealed to be utterly malevolent. He participated in inhumane experiments for kids who have psychic powers known as Grigori Project, befriending a scientist, Koichi Iba. When Iba tries to seeks help to stop Miroku by gathering some information about the project, Yusaka then lets the heroes infiltrate the base, while slaughtering everyone he comes across with a crowbar; he also infects the heroes—including Iba—with a nasty virus. It was also revealed that he brutally kills and tortures some people using a sulfur mustard gas and poisonous moths. When Iba asks him to thank Miroku for his forgiveness, Yusaka just mocks him about it and it was revealed that in the past, he slaughtered the scientists that participated in the Grigori Project and joined Miroku's side so he could slaughter whoever he came across.
• Germans Love David Hasselhoff: More popular outside of Japan than in, where it's ratings are consistently low in comparison with other Jump series. On the popular English manga sites, Psyren regularly was the top on the most popular list.
• Ho Yay: Has its own page.
• Tear Jerker: Ian in chapter 70. He completely fries his brain out, trying to heal all the wounded after the Day of Revolution, after losing everything important to him, including the woman he was in love with and his best friend, Matsuri.
