Yuki is a disaffected middle school boy who has no dreams or goals in life; in fact, the only thing he has is his diary. Writing down everything he observes and documenting every thought, the young boy uses it as an outlet for his imagination. One morning, however, Yuki wakes up to find his cell phone filled with diary entries for the next ninety days. Thinking nothing of it, he continues his morning until he begins to realize that everything on his phone is rapidly coming to pass, and it isn't just mere coincidence. Now, Yuki suddenly finds himself thrust into a survival game against other future diary owners to become the new Lord of Time.
If you enjoyed watching the first series of danganronpa expect something similar for this new anime. I personally find mirai nikki or future diary very similar, since both are about survival and kind of gory animes. Also in both animes the characters are very likable.
22-year-old Ryouta is an unemployed good-for-nothing who spends his days living at home and playing Btooom, a wildly popular online game that's sold over three million copies worldwide. Alongside other teammates, Ryouta battles it out with others using powerful bombs and sonar that can reveal hidden enemies, and his dedication has earned him the title of Japan's top player. But soon, Ryouta's pastime becomes a terrifying reality, as he and many others are dropped onto a tropical island and forced to play Btooom – but this time for real. Now, he and the rest must fight to the death by whatever means necessary, as the only way to win this deadly game is by killing seven of the other players.
Both animes are about high stakes games where the players are forced to kill each other in a remote place with no option for escape except being the last one left alive. All the players have their own psychological issues going on. Btooom! is for slightly more mature audiences though due to violence, gaphic, and adult content where Danganronpa doesn't get quite so heavy or graphic and keeps things lighter with the theme of hope will perservere.
The story follows a group of three friends who suddenly awaken in a completely different alternate world. At first they think it's all a dream or a joke, but they soon realize that the only way to survive in this world is to participate and win deadly survival games.
