B-Rank Rank Battles Arc
Osamu expressed interest to Arashiyama Unit in learning how to fight on his own, rather than relying on Yūma all the time. Although Arashiyama didn't see the need for gunners and shooters to be able to take points on their own, he and Tokieda agreed to teach Osamu the basics. Later, while watching Osamu's humiliating defeat, they express concern over his self-esteem following it. Later, Osamu visits them for more training. Since Arashiyama was away, Kitora teaches him, but with some refusal because of Osamu's apparent arrogance. She teaches him about how to use Spider.
