Eat Some Somen Noodles or Something

With the trouble caused by Acrobatic Silky settled, Momo brings Aira home for a meal alongside Okarun, Seiko, and Turbo Granny. Sensing lingering resentment over the basin she once dropped on Aira, Momo concedes she overdid it and apologizes, yet insists that Aira owes Okarun an apology of her own for toying with his feelings. Aira claims she bears Momo no real grudge; instead she has decided Momo is a demon and an enemy to be destroyed, a label Momo flatly rejects. Pointing to Okarun's shift into a Turbo Granny form and to Seiko looking far too young, Aira treats both as evidence that her accusations hold. The two girls trade jabs, Aira vowing another showdown and Momo accepting the dare.

Before departing, Aira asks why Okarun bothered rescuing a so called demon, and his plain answer, that helping people is simply who he is, leaves her startled and convinced a trace of humanity survives in him. She promises to pry him loose from Momo's influence and walks off blushing, which throws Momo. Later the household uses a baseball game to knock Okarun's golden ball back into place, delighting him. The following school day, Okarun begs off meeting Momo about his missing ball, citing a report he must finish. Suspicious and oddly uneasy, Momo eventually goes looking and is floored to find Okarun pinned on top of Aira.
