Anime and Manga Differences

 * As these scenes were already adapted in the previous episode, Osamu's last visits to Arashiyama and Tachikawa Units' operation rooms before round 5 and Yūma's meeting with Kako, Kakizaki and Kageura are left out of this one.
 * The anime also adds short scenes of Ikoma Unit and Ōji Unit, whose presence was confirmed by a Volume 21 Extra.
