At the swimming pool, Momoko and Hinagiku sees Yuri with a girl who belong to a gang of girls, saying they will meet other guys then left. Momoko and Hinagiku decide to follow Yuri, thinking Yuri left them. Then, two boys attack the girl gang but Yuri manage to make them hit each other. Later, Yuri ask the girl, Hitomi about her dream of becoming a pianist.
Later, Yuri tells Momoko and Hinagiku that the reason she is with the gang is that she is investigating why Hitomi, her childhood friend rebelled. Yuri learns that Satoko, Hitomi's elder sister had taught her how to play the piano but when she died, Hitomi loses her confidence and does not want to play anymore. Yuri plans to make Hitomi play again.
In an open stadium at the park, there is a piano on stage. Yuri says they will lure Hitomi there with Hitomi's favorite piano piece and use an apparition of Satoko to convince Hitomi to play again. Momoko will play Satoko. Jamapi as Satoko's cat. Kazuya will play the piece as Yousuke ties up and pulls Momoko up with a rope on a tree in order to 'float'. Yuri will invite Hitomi to go to their little set-up. Meanwhile, Sandora is meditating as to where the Something Four are.

Yousuke lifts Momoko up as she practices her lines but Yousuke is unconvinced that Momoko can do it then they quarrel. Yuri fetches Hitomi and on their way, ask Hitomi again about her dream. Hitomi tells her that it all vanished when Satoko died.
When they reached the park, it is already sunset. Sandora with his little monster attacks Hitomi. Yuri transforms to Angel Lily but got herself caught. While walking, Momoko practices her lines and sees Angel Lily is in trouble so she quickly transforms to help Angel Lily. Wedding Peach sends the little monster to happy land as Sandora escapes.
It is already night, Yuri then brings Hitomi to the stadium. Momoko realizes that her wig is missing so rushes to find it as everyone is waiting. Hitomi cannot wait any longer starts to leave when she hears her favorite piano piece. Satoko with her cat appears and encourages her to play again as Hitomi chases after her.
