Reine Devila comments about the Something Four combination of the Love Angels. Then, she orders three triplets [women] to find the Love Angels and defeat them. Meanwhile, Momoko, Yuri and Hinagiku are going home from school. Momoko and Yousuke are at it again asking why they are still in school since it is way past the school dismissal -- hinting that one of them is punished by the teacher. Momoko says that she is doing some school paper while Yousuke says that there is soccer practice. Hiromi comes and takes Yousuke away as Momoko looks on sadly.
Nearby, Scarlet feels something in Momoko's school so she rushes there. Hiromi brings Yousuke to the music room and confess her love again to him as the three girls are spying on them. Yuri, Hinagiku and Jamapi tell Momoko to do something but Momoko still hesitates. Hiromi starts hugging Yousuke, telling him to marry her. She then tries to kiss him but Yousuke gently push her away. He tells her that he already has a girlfriend. Hiromi is shocked and starts to cry. Yousuke tries to leave but Hiromi release the dark energy from herself which made Yousuke unconscious. Upon arriving, Scarlet sees the whole school is enveloped by the evil aura. Hiromi transforms to Potamosu and causes the school to turn upside down. She made it fall down to the depths of the evil world, her home.
Momoko, Yuri and Hinagiku are shocked to learn that Hiromi is actually Potamosu then they immediately transform. Potamosu holds on to Yousuke and tries to kiss him but the three Love Angel interrupt her. Potamosu carries Yousuke away as the three chase after her but suddenly, the triplets sent by Reine Devila appear before them. The triplets attack them as they ask the Love Angels to give them the Something Four. Limone comes to help them and tells them to save Yousuke as he handles the triplets. Potamosu uses water to attack the Love Angels who is chasing her. The Love Angels are surrounded by a whirlwind of water which closes on them and squeezes them. Angel Salvia saves them but the triplets appear again who apparently escape from Limone to attack them. Angel Daisy, Angel Lily and Angel Salvia fights the triplets as they tell Wedding Peach to go after Potamosu. The triplets then disappear.
In a room, the triplets appear before Potamosu and tell her that Reine Devila has already betrayed her so the school along with her will be thrown to the blackhole instead of the school going to Potamosu's home. The triplets then accuse her of being like Igunisu who is affected by love that caused her not to complete her mission. Potamosu cries and holds on to Yousuke, saying that she only wanted to marry him in her world but not send him to the blackhole. The triplets is about to attack Potamosu when Wedding Peach arrives. Wedding Peach tells Potamosu to free Yousuke and not force herself on Yousuke because Yousuke does not want that. Potamosu still unwilling as she clings on to Yousuke. The triplets attack Wedding Peach as the three other Love Angels arrive. They combine their power by using their Something Four to defeat the triplets and make the school right side up and go up to its original place.
Wedding Peach tries to convince Potamosu to let Yousuke go but Potamosu is very persistent and starts to wildly attack them. Jamapi tells Wedding Peach that if they do not do something quickly, Potamosu will use up all her energy and will vanish. Potamosu keeps on shouting that she loves Yousuke as she attacks them. Wedding Peach then decide to cleanse Potamosu to save her and Potamosu leaves. On top of a building, Potamosu remembers what she did to Igunisu and that now, she has understand what love can do to a person. She tells herself that she will change and transforms back to Hiromi.
In the park, at night, Hiromi asks for forgiveness from Yousuke for being selfish and for what she did to him. She then says goodbye to him and kisses him on the cheek. Momoko and others who were watching them, are surprised by the Hiromi's kiss. Hiromi runs off as the girls comment about love. Scarlet is doubtful but the three says that Hiromi/Potamosu has changed and that someday she will find someone to love. Then, they see Potamosu meeting a man who looks exactly like Igunisu passing by. She asks him to take her out. The man tells her that she is beautiful. Then the two walks off for their date as the four girls sweatdrop since Potamosu has easily found a replacement for Yousuke.
