Manga: Suicide Island
Suicide Island is a manga that seems to be rather obscure.

The premise goes like this: there have been a lot of suicides in Japan lately. So much that the Japanese government lost a lot of money trying to treat them. So to save money, they give these patients a choice: live or die. If they choose "die", they sign some paperwork and go to sleep - likely assisted with drugs. However, the patients find out as soon as they wake up that they got more than they bargained for. They thought they were going to get assisted suicide, but instead, they were dumped on the titular Suicide Island. The patients find a sign set up by the Japanese government explaining how it is going to be. The patients are considered "dead" to the government, and they can do whatever they want on the island as long as they don't try to leave...and that's assuming that they even find a way to do so! Now the patients must decide what they are going to do.

This work contains examples of:

  • The Archer: The protagonist was in the archery club of his school and uses his knowledge to hunt deer on the island. He has shot at least one person with it, driving him into moral self-doubt.
  • Badass: Sei eventually grows into a veritable one.
  • Break Them by Talking: Kai's favorite method of getting people killed is approaching them when they're most fragile and talking them into suicide
  • Broken Ace: Ryou's natural strength and charisma help the other survivors cling to life, and when threats arise, his presence is usually enough to scare them off. Everyone thinks Ryou so unshakable that they sometimes forget: there's only one way anyone gets to Suicide Island.
  • Driven to Suicide: A Deconstructed Trope here. A number of characters have played it straight, or attempted to, and this resulted in the government wanting to wash its hands of them and save money. Once on the island, many participants decide they prefer to restart their lives; others take the plunge and descend into hedonism, despair, and death. Sometimes with assistance.
  • Embodiment Of Vice: Sawada.
  • Evil Cannot Comprehend Good: Kai, having induced people to commit suicide all along and even murdered someone, doesn't understand why the rest of the main cast want to live so badly. He eventually snaps and tries to kill them all.
  • Go Mad from the Isolation: The old man in the mountain averts this. He actively avoids human contact, yet is possibly the mentally healthiest person on the island.
  • Heroic BSOD: Ryou, after trying to strike out on a raft and discovering that the government will not permit escape.
  • Humans Are Bastards: A major theme of the manga is the adherence to first-world morality in the absence of a justice system: is it noble, or naive? What is the true nature of human beings? Sei's own admiration and respect for the forest fauna leads him to compare the worth of their lives with that of his fellow survivors, who often quarrel and cheat each other.
  • I'm a Humanitarian: Rumor holds that at least one camp on the other side of the island has fallen to eating human flesh.
  • It's All About Me / The Sociopath: Sawada again.
  • Nature Hero: Sei, eventually.
  • Nietzsche Wannabe: Kai. He believes firmly that humans have no place in the world, saying that since the world is so beautiful, why is mankind even on Earth to begin with? He doesn't think that mankind has anything to contribute to the world. He even tries to kill the entire group just because he felt like it.
  • Rape as Backstory: For at least one character.
  • Redemption Equals Death: For Yoshimura.
  • Robinsonade
  • Shown Their Work: The author puts plenty of text explaining things, ranging from the "proper" way to cut your wrists if you want to die, how to make a bow and hunt deer with it, what goat meat tastes like, etc.
  • Team Pet: Ikiru.
  • That Woman Is Dead: One of the survivors tries to fully dissociate from her past, to the extent that she refuses to be named. Sei later helps her to a Meaningful Rename as she decides to live anew.
  • The Needs of the Many: The survivors has developed into this since they decide to be alive, adopting the rule that those who don't work don't get to eat. There are those who just simply take food rather than earn it, but they are losing ground against the rest.
  • Transgender: Tomo's deepest secret, and his reason for being on the island.
