Tamen Mirai: Book One

Kimiko is a powerful being unaware of her ability. Jun goes back in time to warn her not to use her power, but Miko dismisses him because she thinks he's insane. While Jun desperately tries to convince her not to use it, Katsumi, his brother and rival, says the opposite. Katsumi is selfish, power hungry, and just wants Miko for her power ("Future Eye").

If Kimiko trusts Katsumi and uses it, then she will unleash chaos with him and Jun gets publicly executed for treason. On the other hand, if she trusts Jun, who's schizophrenic and sees things that aren't really there, the world is saved and he can finally defeat his brother.

This is an intertwined story about the battle for trust and quite possibly love all while the fate of the world is at state.

It all starts with one decision...
