Long Summary
At Tamakoma's office, Yūma admits to Jin that he may no longer have a purpose in life, but the last few days have been fun. Jin assures Yūma that there will be more fun things in the future. At the same time, Osamu ponders on helping Yūma finds a new purpose and doubt his ability to do so.

As Osamu figuring things out, Shiori asks for him and informs that Chika has decided to join Border in order to look for her brother and friend who were abducted. Osamu attempts to dissuade Chika in order to keep his promise to Rinji. Chika understands the near impossibility of finding her brother, but is surprisingly persistent in her desire to join. Shiori explains that it is unlikely for a newcomer, such as Chika, to join Tamakoma right off the bat. Instead, she has to enlist at the HQ and form her own team before transferring to Tamakoma.

Osamu relates Chika's decision to Yūma and invites him to join them, saying that they need a strong leader such as Yūma. However, Yūma is reluctant to join, but surprises Osamu by noting the similarity between Osamu and his father. He then asks Osamu why he fights, even by risking his own life, for others. Osamu explains that if he runs even one time, he feels he may run when he really needs to stay and fight. Yūma stands up and declares he will help them out. They then meet up with Chika, who is waiting downstairs, and Yūma informs her that he will be joining their team, but adds that he will only join on the condition that Osamu becomes the leader, which Chika agrees. Then, they head to Rindō's office and find the applications already prepared. Yūma asks Jin if he saw this with his Side Effect, and Jin reminds him that he said there would be more fun things in the future. Rindō officially welcomes the team to Tamakoma Branch as they prepare to aim for A-Rank.
