The students of 3-E turn a surplus of eggs to good use—in pursuit of their usual goal. Karasuma teaches them the art of parkour while Koro Sensei teaches them the game of cops and robbers. Then, someone is stealing lingerie, and naturally Koro Sensei is the prime suspect! But is he being framed…and if so, by whom?
Lastly, biologically modified Itona discovers that sometimes tentacles can be a burden rather than a gift. He puts everything he’s got into his latest assassination attempt on Koro Sensei…but who will save Itona from himself?!
