I think fanon Chen actually kind of works here - the contrast between that and this Chen's standard violent cruelty is actually pretty interesting.
You should have realized it the first year, that was more than enough proof.Remember it.Like Memento.Wait, that last one.No, he doesn't.Flan-chan said Santa-san doesn't exist!Kakka is just CG.Win and Rule
ChenThere's no Precure either!?Sieg HeilIncidentally, Yukari believed in Santa.Sex with Mokou
KeineI want to quit
NueWere you two angels?She knows how to fight like a weakling.She's closed off her heart again.Just like Precure and Demon Kogure.
Demon Kogure Kakka is a musicianHe doesn't! Onee-sama said so while crying!!Do master and servant both forget everything from the year before?Santa-san does exist, Sensei!Really now... What are you two doing? If it's over Mokou, she's mine.Chen will be sent flying without a trace, fight over.Right, this story is over.That's such an unexpectedly cute reason, it almost made me think I was a disgusting existence.Keine, there's trouble! Chen and Flan are fighting!Well then it's no wonder that after years of trying to capture him with poison cookies, all I got lying by my bed was Ran-shama naked in a stocking!I don't believe anyone anymore!!But Chen is using battle strategies like using other students as shields, and wearing down her opponent's strength with traps...Chen
TewiPlease, stop!
Mokou
