トライアングルカノン ～もうひとつの奇跡の物語～

It was snowing again today in this town after a seven-year absence.
In this town that I have returned to after a long absence, I meet a girl.
Misaka Shiori - a girl with a sad fate.
Then, reunion.
Ayu Tsukimiya - the girl of promise, and Nayuki Mizuse - his cousin.

It is a blank seven years... A piece of memory that has been tucked away in the memories. As if to make up for this time that has been waiting for them, The gears slowly start to move. And in the end, I wish you a happy time.
