Chen's outfit seems to have gone from having a big yellow ribbon in the front, to having a necktie, to having what may or may not be pockets, to having nada, to having those possible pockets again.
Just interesting tidbits.
Homework
Capture the runaway students. Dead or alive.
Reward: A hot kiss from SenseiBut I don't think it's the wrong solution for this.Well it's not like I don't have problems, but...I mean, I was the one who spread it, but...Why are you trying to act like a teacher all of a sudden?Day Duty
Chen
Unbelievably, it's Flan-chanRolling on the floor.And I'm gonna exaggerate it as much as I can!Then I'm gonna spread it all over Gensoukyou!And finally I'm going to have it be that you got fucked by your sister.Hmm, well I guess it's fine.The thing is, I've been hearing that my older sister abuses her pets...There's been rumours that Orin was fucked by her master recently.You two caused this.So are you pregnant, or suffering from gender identity disorder?I was watching reruns of Kinpachi-sensei yesterday.Is something wrong? You can tell Sensei anything.Koishi, it seems recently like you're not heading home after school.Right, that's the rumour Chen spread.Huh? What are you talking about? Of course I'm gonna laugh.Don't go confusing it with the worst thing.Are you sure that wasn't Kitano Takeshi?
"Making students fight to death" is a reference to Battle Royale. The teacher from this movie who's played by Takeshi Kitano and hosts the death game is a parody of Kinpachi-sensei.So what did Kinpachi-sensei do in this situation?...You won't laugh?Pretty certain he had the students fight to the death.But the truth is, Orin was the one taking the mounted position.
