Stairs - Die Treppe

Nora did not realise that a classmate is trying to confess to her and rushes off to home after her club practice.
Shinku, Jun and gang is hooked on a doll detective show with the lead being a doll called KunKun. While they're engrossed in the show, Hinaichigo's strawberry is stolen by Suiseiseki. Hinaichigo is angry when Nori believes Suiseiseki's claim that HInaichigo finished her own strawberry and is so selfish as to covert Suiseiseki's as well. All riled up, Hinaichigo decides to go on a strike on the second floor with Jun as her ally. Their antics caused Suiseiseki to launch an offensive from the first floor. Tricked by Jun/Hinaichigo, Suiseiseki finally admitted she's the culprit. Nearing to dinnertime, Suiseiseki tries to tempt Jun/Hinaichigo into surrendering by emptying the fridge's contents and eating the goodies in front of them.
To get Shinku on their side, Jun comes up with a plan to use a KunKun doll to lure Shinku in. However, he didn't expect Hinaichigo to lurch forward
