Miko Iino Can't Make Him Answer is the one hundred-eighty eighth chapter of the Kaguya-sama wa Kokurasetai manga series.
Miko and Yu play Shiritori to solve an argument.
The chapter continues Kaguya’s walk with Shirogane. On their way to see Iino and Ishigami, they wonder if the duo resolved things while they were away. Much to their surprise, they walk into Ino and Ishigami, fighting and calling each other names.
Fujiwara tries to break the fight by suggesting that this should be resolved with a battle of wits and not strength. She suggests a card game in which players have to play cards to create words.
Iino takes the lead at first and is one step away from winning, but Fujiwara keeps suggesting lewd words to her.
This makes it very hard for Iino to play those words, and Ishigami ends up winning. Iino still refuses to apologize, and on further discussion, it turns out that she was in the right.
The chapter ends with Fujiwara challenging Ishigami to a card game and using all the lewd words possible to win.
