Differences Between the Anime and Manga

 * In the manga, Sakurako makes no comment about Osamu after Azuma points out he positioned himself in a strategic position, and Tokieda and Arashiyama don't say anything after Kitora says it was just a coincidence.
 * In the manga, when Azuma says the match is over, Osamu is seen before Azuma says Tamakoma won, and then shoots Suwa, while in the anime, Azuma says Tamakoma won before Osamu is seen.
 * In the manga, Osamu, Chika and Yūma don't fist bump.
 * In the anime, when Tokieda says Mikumo Unit is strong, Kitora looks away, apathetic. In the manga, her reaction isn't seen, as she's off-panel.
 * In the anime, Sakurako doesn't ask Azuma for his opinion on the battle, instead just informing the spectators about the updated ranking. Azuma's opinion and Kodera's explaination about Mikumo Unit's strategy are adapted in the next episode instead, as is the announcement of Mikumo Unit's next match.
