The writing on the board is a reference to this IOSYS song right?
Ohhh... History! ♥If that fo—?Perfect Memento in Strict SenseToday's goal.Stop telling sensei she's creepy or something like that.Sensei is a human too.Phenomena that repeat endlessly are, as a matter of course, written down by Man into the annals of history.I'll never get up again if my heart is broken.The most effective method to ensure that they are neglected, abandoned and concealed in the shadows of history as vestiges of forgotten truths is to devour them completely, leaving nothing behind.
