Masato Kageura

"We don't care about away missions. But... we're not going to let people weaker than us gey ahead. If you want to get up to A-rank, you'll have to go through us first. Shrimp."

- Masato Kageura to Yūma Kuga

Masato Kageura is a B-rank (formerly A-rank) Attacker and the leader of Kageura Unit.

Appearance
Kageura is a young man with wild black hair and light-colored eyes with slit pupils. He is usually seen wearing a dark sweater and jeans and a mask on his jaw, which he uses to hide his jagged teeth as well as to minimize the areas of his body susceptible to his Side Effect.

Personality
Kageura is extremely belligerent, decapitating two trainees for talking about him behind his back. This is due to the unpleasant sensations caused by his Side Effect when people feel negatively about him. Murakami describes him as "aggressive and tactless, but [...] simple and real". He also hates when people are late, getting mad at Murakami and later Yūma, for being late to meet him on separate occasions. Also, despite his aggressive demeanor, people who know him well don't seem to mind it at all, possibly because they know of his Side Effect. He can be very blunt, trying to provoke Yūma as soon as they met and revealing Ema's crush on Chika to a whole table of people while Ema himself was present.

Kō Murakami
They seem to have a good relationship, although Kageura is annoyed of Murakami. He was also delighted by the idea of Murakami being defeated by Yūma. Despite this, Murakami seems to consider Kageura a nice guy, since he always takes Kageura's threats and insults lightly.

Yūma Kuga
Yūma and Kageura seem to have a good relationship, despite their rocky start. During the 4th round of the rank battles, they assist each other in defeating Sumiharu Inukai and Shinnosuke Tsuji to save Chika, despite being on different teams, and they later schedule a ranked match, although Yūma gets lost on the way there and is eventually "summoned" by Mikumo. Murakami stated that Yūma would appreciate Kageura's honest nature, and would be compatible with him. Eventually, Kageura admits taking a liking to him due to Yūma being able to fight him without triggering his Side Effect.

Yuzuru Ema
They seem to have a good relationship. Ema appears to be Kageura's only teammate who doesn't make him easily mad.

Hiro Kitazoe
Kageura seems to be annoyed by Zoe's emotional outbursts, although Zoe likes him. The two became friends after eight rounds in a solo battle.

Nozomi Kako
Kageura seems to dislike Kako, as he calls her "phantom hag". Kako is much more playful towards him however, and doesn't seem to mind his insults. He also fought with her over Yūma, as he has a ranked match scheduled with Yūma while Kako wanted to recruit him.

Sumiharu Inukai
Kageura hates Inukai, but the latter does not care about it.

Eizō Netsuki
At some point in the past, Kageura snapped at Netsuki and hit him with an uppercut, leading to the demotion of his unit.
