After using his special summon to do some manual labor for the teachers, Akihisa sits down to a nice lunch consisting of 1/67 of a dry ramen cup, which he got by cutting the ramen in half constantly until he arrived at that fraction (note: the closest in real life would be 1/64, but he's not that smart).
The rest of the episode consists mostly of Akihisa trying to get some lunch. Minami wants to give him her bento, but he's afraid of her. Mizuki offers to share her lunch, but everyone who eats it mysteriously collapses in pain. The boy who's secretly in love with him offers to treat him to lunch, but his summoned monster accidentally loses all its HP, forcing a teacher to drag Akihisa back to school for "supplementary lessons" before he can eat. Will he ever find time for lunch?
