Tamakoma Second, Katori Unit, and Kakizaki Unit prepare for their Round 5 Rank Battle, with Katori Unit experiencing heavy tension between Wakamura and Katori. The Rank Battle begins, taking place in an industrial zone.
Osamu discusses the two enemy teams. Katori Unit has an ace, Katori, who is responsible for the downs, and she is supported by her teammates. Kakizaki Unit, on the other hand, had all members relatively equal in terms of responsibility. As both teams possess no Snipers, Chika will be the key to victory. Osamu predicts that Kakizaki Unit will choose a setting with many buildings to make things harder for Chika. Kakizaki Unit discusses the choice of their map, which is an industrial zone. Their plan is to use the buildings to hide and get close to Chika, and then take her out. Kakizaki compares Tamakoma Second to Katori Unit in that both teams have aces, both of whom must be avoided. Kakizaki informs them of Tamakoma Second's goal to join the Expedition Force. He declares that they would not let Tamakoma Second win, though. Katori Unit is studying the other two units, but Katori shows no interest in doing it. Wakamura chides her for not being more involved, noting that their team was dropping. Katori states that if it's the case, then it's the case. Wakamura alludes to Katori's attitude, and recalls former incidents where she simply gave up after encountering a challenge. Katori tells him that she would not tolerate being criticized by someone less talented than she. He yells at her, telling her to actually try before deciding that things are not worthy of pursuit. However, she totally disregards this, and Somei informs them the battle is about to begin.
All the teams teleport into the map, scattered. Osamu orders Chika and Yūma to rendezvous with him. However, Katori approaches Yūma.
