So in episode 6, the MC's imouto dies by collapsing her school building, which sends the MC into depression. Nao follows him around being invisible to him and eventually stops him from when he was about to light up a cigarette,managed to make him come back to his sense. In ep 9, she goes to a concert with the MC. During the concert MC suddenly gets flash backs of an alternate time lime and afterwards wakes up in the hospital with Nao sitting by his side.
Turns out his brother has the ability to travel back in time, I'll spare you the details about that but MC steals the brother's ability and travels back in time. Basically nullifying everything that happened in episode 6 to 9. He keeps his imouto from dying this time.
In episode 11, some terrorists kidnap one of the characters and Nao.They send MC because he's "the strongest" but utterly fails to do anything at all and just gets his eye rekt meaning he can't travel back in time any more. The building collapses due to him going crazy because of the ability he stole from his imouto. This nearly killed Nao, who was still tied up in the basement but got saved by that other character, who did die.
MC after talking to his brother decides to go on a world tour, and confesses to Nao that he likes her. Say it was because she was with him all the time during his depressive episode, to which Nao just said "That probably was my way of taking responsibility". Nao basically just what the fucks at him (pic related) and says they are incompatible but still ends up promising him that if he comes back, she'll be his lover.
So here they have the last episode where the MC goes on a rampage through the entire world stealing people's abilities. But it's all just crammed into a single episode.
He comes back, doesn't remember anyone nor Nao, which makes her cry. I'll spare the rest because it's not that related any more.
