Kanokon - Season 1 Episode 3 Eat Deliciously?

Kouta is the prize in a battlefield fought with food between Chizuru and Nozomu, but neither of them can cook well and Kouta is the one suffering as he is forced to eat terrible food experiments concocted by the two girls. Chizuru and Kouta also get attacked, but Kouta takes the hit for Chizuru and is knocked unconscious. Feeling guilty the attackers (which one of them is a frog spirit) tries to help Kouta by making toad oil (even though she is a frog spirit) and Chizuru cannot help but get more intimate with Kouta by rubbing the oil in with her body, but Nozomu joins in and Kouta panics again. Back at school, a fight breaks out between Chizuru and Nozomu that leaves Kouta shouting at Chizuru and then she cries and runs off. Kouta soon follows finding out that Chizuru was faking it and that she just wanted some alone time with Kouta in a very playful way.
