Potamosu tells Reine Devila her plan of disguising herself as a human being. Reine Devila agrees to her plan and orders her to go to the Love Angel's school and get the Something Four. Potamosu changes her appearance to a student and calls herself Hiromi. In science laboratory, Momoko and others try to befriend her. When Hiromi becomes very friendly with the guys who have a crush on her, Hinagiku feels some bad vibes. The three girls comment that Hiromi easily becomes the center of attention of lots of guys even though she is just new. Yuri and Hinagiku are not very happy about it but Momoko tells them that they should not pay much attention to Hiromi and just watch the soccer game.
During the game, the soccer ball falls near the three girls and Momoko picks it up. Hiromi immediately grabs the ball from her and toss it back to Kazuya. Hiromi comments that Kazuya is nice and handsome. This made the three girls worry because they will have a new competitor for Kazuya. When Yousuke walks by, Hiromi blushes and feels her DNA beating. The three girls start fighting again regarding Kazuya but Hiromi interrupts saying that they should stop it since she is the most beautiful of them all. Yousuke then wipes his perspiration with his hand. Upon seeing this, Momoko takes a towel from her bag but Hiromi grabs the towel.
The three girls thought that Hiromi will go to Kazuya but to their surprise, Hiromi bypasses Kazuya and goes directly to Yousuke. Hiromi then uses the towel to wipe Yousuke's perspiration. Yousuke is surprised by this and tries to avoid her. Hinagiku is happy that Hiromi does not have a crush on Kazuya but Yuri tells her that Momoko does not look too happy. Momoko cannot believe that Hiromi likes Yousuke and is disappointed to know this. Hiromi starts holding Yousuke's hand and tells him that she cannot help herself because she is feeling her DNA. Hiromi wonders why her heart is beating so fast.
That night, Momoko is very angry and apparently jealous as she is pulling the cotton from her pillow. Jamapi comes by to tell her that the phone is ringing. It was Hiromi who asks her for some information about Yousuke since they are close. After the phone call, Momoko continues to pull the cotton from the pillow, wondering why Hiromi of all people would call her.
During soccer practice, Yuri and Hinagiku notice that Momoko is not in her usual self. Hiromi comes by with some drinks for the soccer team because she is now the manager of the soccer team. Hinagiku and Yuri are angry that they did not think about it first since it is a good way to be close with Kazuya. Hiromi is helping Yousuke out that made Yuri and Hinagiku tease Momoko who denies that she is jealous. During a soccer match, Yousuke hurt his leg. The three girls offer to help him by rushing to the clinic but Hiromi is already with him who tells them that they should not try to get in the way.
Hiromi bandages Yousuke's leg as Yuri and Hinagiku spies on them. Momoko does not want to watch the scene. Hiromi is flirting with Yousuke and declares her love for him. Yousuke tells her that he likes soccer more than girls and quickly escapes. The two girls still kept on teasing Momoko who is getting jealous. The three girls decide to go back and watch the game. Hiromi is very angry at Yousuke who rejected her so she calls out some Shimo-shimo [turtle creatures] to freeze people.
The three girls then saw a couple in ice. Jamapi tells them that it is the work of Shimo-shimos who freezes people who are in love. They found Shimo-shimo who just froze another couple. They transform and send it to happy land. Back at the game, they cheer for their team. Hiromi sees them and feels that she still has some feelings for Yousuke even though she is rejected by him so she also starts to cheer for Yousuke.
