At the beginning of this episode, Takumi no longer has the Faiz gear. It was surrendered to the Chief of Smart Brain in the previous episode. He appears to be a bit depressed and takes off on his own for a bit. In the meantime, we learn that the Chief has made Naoya the new Faiz and learn that the Chief's philosophy regarding Orphnochs is if they don't attack humans or if they defend them then they are worthless and are to be eliminated. Yuji still considers himself human and doesn't want to attack humans. Naoya calls him out to fight him but hesitates during the fight. Yuji, in Orphnoch form, disarms Naoya bringing the fight to an end. Yuka and Keitaro find him.

Takumi wants to revive Mari and Masato knows that the only chance she has lies with Smart Brain. Yuji finds out that Takumi is not the one that injured Mari. Masato wants to give away the three belts for her life, but decides that his mission to destroy Smart Brain is more important than Mari. Takumi goes to the chief of Smart Brain and asks to revive Mari. He says that he'll only do it if he becomes a member of Lucky Clover by killing Aki.
