Wow. That was such a confusing intro. But, I like it all the same. The anime shows alot of promise, and I'm hoping to get alot out of it.
Looks like its gonna be one of the better new ones.
This is purely a guess, but Chihiro seems to forget everything that happened the day before.
I'm guessing she wrote it all down in that diary of hers, then read it as soon as she woke up. All she had was a name, but she didn't recognize Asou when she saw him the next day.
Whatever it is, this show looks promising and the characters are more than alright.
