However, her skills as an assassin relies on infiltration and deception, and since her cover is blown, she's pretty much useless in current situation. There are many assassins far more skilled than her in simple "art of killing", including the other transfer student who's coming here. He passed the test with incredible results.

Koro-sensei backs Bitch-sensei by saying although it is true that Bitch-sensei's skill as an assassin isn't very formidable at all, she is more fit an assassinate in his classroom. To prove, he propose a duel between the her and her master in art of assassination to prove his point.

Ohhh that explains the pictures of assassins when he was talking. Thank you for clarifying that. Soo will he be a teacher for class E given that he did mentor Bitch-sensei. The subject he could teach could be history/history of assassin. Still I wonder what test would it be surely it would have to do something with killing kuro sensei? Also is it a safe bet to say there going to be a school festival arc. Because that could be funny in terms of kurosensei and his love for food and sweets.
