It's revealed that Nayuta had gathered the data for a leaflet and declares it to be sufficiently full of personal data. Mahiro points out that there's no data on Nayuta in it however and decides to fill it out. Mahiro asks Nayuta her weight and her three sizes, but Nayuta declares Mahiro to be rather inconsiderate for asking her those things. Mahiro in turn declares Nayuta to be unreasonable since she got everyone else's but won't reveal her own.

At that point, Mai and Miyako come up to Nayuta to introduce themselves, saying that it's nice to meet her. Nayuta in turn hides behind Mahiro in fear, noting that she does not posess data on either of them. As Mai and Miyako get confused expressions on their faces, Mahiro thinks to herself how socially stunted Nayuta is.
