Masataka Ninomiya/Relationships

Mirai Hatohara
Ninomiya has very little respect for his former teammate, possibly due her breaking Border's rules by giving triggers to civilians, which demoted them to B-rank. It seems he still cares about her, however, as when there is a lull during the round 4 battle, there are 5 snowmen seen around him, totaling the number of members in his unit including her.

Kōhei Izumi
As top-tier Shooters, both of them have respect for each other and their opinions. Despite being the No.1 shooter at the time, Ninomiya asked Izumi to teach him techniques he lacked.

Kei Tachikawa
Ninomiya seems to dislike Tachikawa, as he gets bothered with Tachikawa's comments during Tamakoma Second's third match.

Nozomi Kako
They seem to have a strained relationship, as Kako becomes annoyed when he takes the lead during the Galopoula Invasion.
