Yukihime

The protagonist had been living an aimless high school life ever since losing his father in an incident a year ago.

His childhood friends Mizuki and Ayako each tried to encourage him in their own ways...

It was then that a transfer student came bursting into their lives.
The transfer student's name was Omiyama Yuki.

But that nostalgically familiar name was also the memory of an unforgivable sin between two people.
