Plot[]
Rito, Lala, and Mikan are ice-skating at Sainan Skate. While Mikan notes how Lala is very good to skating, Rito continually trips. Rito wishes he had stayed home, but was afraid he might be targeted again. When Mikan ask who is the killer girl called Golden Darkness, she appears right then. Yami then reminds Rito that he is her target, and she is watching him at all times. Just then, Yami gives Lala a taiyaki as a thanks, but she is too embarrassed to say thank you and runs off.
Suddenly, Haruna, Risa, and Mio show up. Rito wonders why they are here, which Lala takes credit for thinking the more the merrier making is happy about. Mikan then notices Rito's interest in Haruna again. Later, while skating, Mikan insists that she skate on her own and that Rito should practice with Haruna. Rito then wonders if Mikan noticed that he likes Haruna. Rito then goes to skate with Haruna who, as soon as she gets on the ice, falls down on Rito, and apologizes. Both say that it is their first time skating.
While racing with Risa and Mio, Lala uses her "Almighty Tool" to make rocket boots. Lala then spins around in a circle crashing on Rito and knocking Peke off leaving Lala laying on Rito naked in front of everyone. Meanwhile Yami walks by, wondering the primitive enjoyment in skating. Just then, Peke is caught by Yami and she transforms her clothes into a school swimsuit embarrassing her. Yami then throws Peke away and she hits Mio turning her clothes in a flashy dress. Once Risa touch Mio, Peke is transfered to her who is now wearing sexy lingerie. A dizzy Peke tries to reach Lala, but lands on Haruna instead transforming her clothes into Lala's standard dress. Rito then pulls Peke off of Haruna and Peke transforms his dress into the naughty outfit from chapter 26. Haruna, horrified, scream while Rito try to explain.
