Choujin X, Vol. 7 (manga)

Tokio is back from his training just in time to help Ely and Azuma deal with some troublesome choujin on a plane. But tearful reunions will have to wait as Yamato Mori dedicates all its resources to preparing for all-out war against Zora and her forces. As Tokio and his friends get caught up in battle strategies and reconnaissance missions, they are viscerally reminded that there’s one experience all choujin have in common—pain.
