Nasa's apartment has completely burnt down. Have they lost everything? Well, nobody got hurt and the plant commemorating their marriage is miraculously intact and Nasa is very relieved. And what about the other stuff? Tsukasa has married a provident boy and guess what? He is already organized and his bank book and other important things are in a safety deposit box. Still, what can they do about a new place?

Nasa suggests takoyaki party to the Arisugawa sisters so that everyone can get to know each other better. Meanwhile, Chitose tracks Tsukasa down to the bathhouse. The game-loving Aya finds herself getting along with the two of them, and before long competitive sparks start flying!
