Rentaro Satomi vs. Shougen Ikuma

Rentaro Satomi vs. Shōgen Ikuma is a fight between Promoter of Tendo Civil Security Corporation Rentaro Satomi and Promoter of Mika Island Civil Security Corporation Shōgen Ikuma.

Prologue
After returning home from the mission of locating the Gastrea that invaded the Tokyo Area a day prior, and confronting the infected Sumiaki Okajima, Rentaro is informed by Kisara Tendo, his corporation's president, of a meeting they were summoned to at the Ministry of Defense. The two soon exit Rentaro's school and head to their destination, on a train. When they finally arrive, a lady escorts them to the room where the meeting will be held, with Rentaro questioning if Enju should be here. Kisara informs him that her presences will not be necessary as they will solely discuss certain events. Their conversation is cut short when the woman calls their attention to tell them that they have arrived to the room, pointing towards a large door. Entering, they see many Civil Securities present. Shortly thereafter, they begin to walk deeper inside, and a hefty man appears behind Rentaro, insulting them because of their age.

Battle
Rentaro steps up and confronts the man, asking him for his company's name. However, Shōgen simply smashes his forehead into Rentaro's without answering his question, pushing back. As Rentaro falls to the ground, Kisara shouts out his name, leading him land on his hand and regain his balance. Shōgen grips his hand and calls Rentaro detestable, with Rentaro returning the insult. As Shōgen reaches for his sword, Rentaro holds his XD, in preparation for attack. Shōgen chuckles, questioning Rentaro's tool's whereabouts, noting as he is a Promoter. Confused, Rentaro can only stare at him as he questions the meaning behind his words; Shōgen reveals to be talking about the Initiators. Before Rentaro can reply, Kisara comes next to him, reminding him of the reason they are here. Shōgen, however, angrily asks Kisara to get out of his way. Before Shōgen can attack Rentaro once again, a man tells him to stop, and that if he does not wish to, he can simply leave.

Aftermath
Shōgen steps down, heading towards his Initiator's location. When Rentaro looks at them, he ponders if the young girl next to him is his Initiator. Not long after, Kisara admits to Rentaro that she is glad Shōgen was stopped, revealing his IP Rank to be 1,584, shocking him beyond belief. Minutes after, the meeting begins, with Seitenshi being the one to deliver the missions to the present Civil Securities. However, as she does so, the masked man appears to wreak havoc.
