Members of the Ryusei School are trying to find the Delta belt and are arguing over it at the same time. Itsuro of Lucky Clover continues to try to kill Yuji. As they are fighting, they run into Keitaro and Saya. Keitaro encourages Saya to run and soon Delta appears on the scene. Everyone thinks that Aki has the Delta belt. Kyosuke and Ken kidnap Mari to lure out Aki, who continues his murderous rampage as an Orphenoch. Aki kills Kyosuke and Ken as Takumi and Masato arrive on the scene to save Mari. Delta arrives on the scene.

Faiz and Kaixa are fighting Aki with little success. Before Delta can join in, Mari intervenes and Aki escapes. Everyone is still trying to figure out who has the Delta belt. They are beginning to suspect that maybe Saya has it. The belt was originally sent to her. Mari and Masato try to arrange a meeting with Aki. In the meantime, Itsuro meets up with Kitazaki. Anyone who Kitazaki touches dissolves. Three crooks found that out when they tried to steal from Kitazaki. Aki eventually meets Masato and Mari. He tells Mari that he has always liked her. By killing her he can completely throw away his humanity and grow stronger as an Orphenoch. He and Masato transform and fight. Takumi arrives to fight Aki as does Saya. Sawada kills Saya and gets the Delta belt. He is made a part of Lucky Clover.

As Masato is about to deliver the rider kick, Mari intervenes. Takumi gets there just in time to save her by blocking the kick with his bike. Takuma tries to steal the Delta gear from Kitizaki. Mari arranges to meet with Aki again. However, before she does Takumi meets him. Aki tells Takumi that Mari is the only one who can help him become human again. When Mari arrives she is attached by Saeko's Orphenoch assassin again. As Takumi battles him he encourages Aki to take Mari to safety. After saving her again Aki punches her hard enough to send her flying into a building. She is hospitalized. Naoya and Keitaro manage to save a child from a fire. Masato makes Yuji believe that it was Takumi that injured Mari.
