The recap is handled more gracefully than typical clip shows, according to the review, and it serves to remind viewers of the stakes before Kiriwo and his cronies return to Babylis.\u003c/p\u003e\u003cp\u003eThe episode's key development is Poro's decision to side with Kiriwo's minion Toto. Poro initially prepares to take Toto out, but changes course when Toto mentions the possibility of seeing Derkila again. The review notes that Poro's loyalty is to his ideal of Derkila, not necessarily to Derkila himself, and that he is willing to discard his integrity for that chance.\u003c/p\u003e\u003cp\u003eMeanwhile, Asmodeus begins to suspect something is off about Kiriwo during a conversation in the clubroom. He recognizes the signs of an evil cycle that Balam taught him about, confirming Balam's effectiveness as a teacher and reminding viewers that Asmodeus is a sharp student in his own right. However, Asmodeus also realizes that Iruma never told him or Clara about Kiriwo's true nature, and the review suggests this could lead to tension between the two friends.\u003c/p\u003e","blueskyPost":"Poro's willingness to ally with Kiriwo's faction for a chance to see Derkila introduces a moral trade that the show has not previously asked of its supporting cast.","twitterPost":"Poro's betrayal introduces a moral trade the show has not asked of its supporting cast: integrity for a glimpse of Derkila.","threadsPost":"Poro's betrayal in Iruma-Kun Season 4 Episode 9 is not a simple heel turn.
