Ms. Sato has a pretty nice design, gotta say. Was a fun little VN to try out, I do like a teacher-student thing though, so a bit biased. Ms. Sato getting into it before the To Be Continued though... seems the student is in for more then he bargained!
On a selfish level, since the game is still being updated, sure hope a side story can include some classic yakyuken or something!
