Saiki Kusuo no Ψ-nan 2 - episode 19 - 22 May, 2018

Kusuo's class has to choose two organizers for the school festival but not Hairo or other girl who did it last year. Kokomi manipulates the situation so that she is partnered with Kusuo and that the class will perform a play. Kusuo gets his friends to join them as they think of what kind of story to do, resulting in them sharing some fairy tales. They agree to do their own rendition of Momotaro. While cast in a minor part, Kusuo watches the dress rehearsal where he learns that Saiko has bought all the costumes and scenery in order to have a starring role, but Saiko withdraws his support when he learns Shun was trying to trick him. The class performs anyway without costumes, but when Kokomi arrives to wow the audience with her acting and Kusuo helps hypnotize the group into thinking they are still wearing costumes.
