桜塚 白雲

Tsukumo was adopted when he was very young kid - in 1999 - by the Sakurazuka family following the loss of his family because of a natural disaster in 1996.

At first, he couldn't think of Natsuki as his sister until she saved him - the same year - from drowning, getting hurt herself in the process. Ever since, he has been devoting a deep love to her, more than brotherly.

Tsukumo rarely loses consciousness after a fight, even if it was a difficult fight. On the other hand, Mimi's kitchen nearly sent him to the other world ...

After rescuing Mimi from a bunch of mobsters, she declares her love for Tsukumo who tells him he will think. Tsukumo then declares his love to his sister but is rejected. He then agrees to go out with Mimi as a friend, but the more time passes, the more Mimi is in love with him. Naive but smart, Mimi understands that Tsukumo loves someone else and asks him an ultmatum ...

If Tsukumo don't see Mimi as her person only for him, he breakup with her. If he choose to have sex with Mimi but can't forget his love for Natsuki, she breakup with him. If Tsukumo choose Mimi, they stay together.
Although he doesn't see Mimi as a romantic interest, Tsukumo loves her a lot and is very angry at him for breaking her heart.

When his sister gets sick, he learns from Kirihiko that this is probably due to poisoning. He thinks she was poisoned the day she saved Tsukumo from drowning years ago.

When she dies, Tsukumo is destroyed but manages to recover thanks to his entourage and decides to save his sister from "himself" by preventing her from hurting herself in the past.

So begins his incredible journey through the Time .../
