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 lanky, light-skinned young man with wild black hair and amber-colored eyes with slit pupils. He may hide his jagged teeth with a surgical mask, which also serves to minimize the areas of his body susceptible to his Side Effect. His casual outfits invariably include a black sweater, sometimes with a zipper and often with a high collar. He is also seen wearing jeans or cargo pants with front pockets and zippers, as well as black shoes.

Kageura's uniform is comprised of a double-breasted, black military jacket which folds over the right side, where the coat is fastened by a vertical row of five buttons. On the wearer's right breast are two piped patch pockets closed by the same flap, and a second pair recurs at the height of the wearer's abdomen. Kageura Unit's logo is emblazoned on the jacket's high collar. Gray plain button epaulettes adorn the jacket's shoulders. The attire is completed by light gray cargo pants with a piped patch pocket and a zipper on the front of each leg, and black combat boots.

Personality
Kageura is very belligerant, decapitating two trainees for badmouthing him behind his back, although he would not harm anyone who is not in a trion body. His violent behavior stems from his Side Effect, which not only lets him know how others feel about him, but also produces a prickling sensation that is all the more unpleasant if the emotion is negative. The distress caused by the ability led Kageura to detest it. He has recently taken to give a second chance to the ones who mock him to themselves, although he does not warn them about his Side Effect, but he will not hesitate to raise his hands against them if they do not relent, claiming that he'd rather be demoted than allow himself to be berated. Onlookers who become afraid of him due to his outbursts he may try to scare away in a non-violent, facetious way. He can be verbally abusive even to those who do not provoke him, and he may be very blunt even to his friends, casually revealing Ema's crush on Chika to a whole tableful of people while Ema himself was present. Murakami describes him as "aggressive and tactless", but "simple and real". He loses his patience easily with tardy people.

Kageura profoundly enjoys fighting skilled opponents, and it is not uncommon for him to pursue his own amusement during rank battles at the expense of strategy. He takes a very relaxed approach to the competition, refusing to watch the logs of his opponents unless they pique his interest. Nonetheless, he will not allow his unit to be outranked by any one he perceives as undeserving. He started making more of an effort to lead his unit after Ema expressed his desire to join the away expedition, although the pressure ended up affecting his performance negatively the first time he attempted to play the match more strategically. Despite feeling the sting of failure, however, he remained determined to help his teammate.

Kō Murakami
Kageura and Murakami are friends, rivals and classmates. They often spar together in their free time, or hang out at Kageura's family's restaurant, where he invites only his closest friends. Murakami can shrug off Kageura's aggressive or mocking tone with a smile when it is directed at him, although he does not approve of him being rude to people who do not deserve it. He knows him well enough to tell that when he does seriously snap, it is not completely unmotivated, quickly inferring that the two trainees whose trion bodies he destroyed had continued mocking him despite his warning. On that occasion Murakami assured them that Kageura would never lay a finger on them while they are in their flesh and blood body, and then proceeded to further scare them by telling them that Kageura was able to read minds. His comments to Kageura after the fact only expressed concern over his conduct causing him to be demoted again. For his part, Kageura seemed to feel the need to explain his actions to his friend. Murakami appears to sympathize with Kageura due to the pain caused to him by his Side Effect, and, despite his difficult personality, will introduce him to people which he believes Kageura will get along with, although he may give them pointers on how to behave around him beforehand. Their friendship does not prevent them from going all out against each other in rank battles, and Murakami has no qualms about acknowledging Kageura's superiority in combat. Kageura addresses Murakami by his first name, while the latter uses a nickname.

Yūma Kuga
Yūma was introduced to Kageura by Murakami upon hearing that they would clash in round four, and thinking that their personalities would be compatible. Kageura was amused by the thought of Yūma defeating Murakami and Arafune, but refused to fight him and give him information. Nonetheless, he was impressed with Yūma effortlessly shrugging off his attempt to rile him up. He grew more interested in the Tamakoma Second Attacker after watching the logs, and made him his designated target for the match. Later, an amicable rivalry developed between the two as they begun to compete in solo rank battles, followed by genuine friendship. Kageura's closest friends remarked that he had taken quite a liking to Yūma, going so far as to invite him to his family's restaurant. Each Attacker holds the other's skill in high regard, with Yūma's ability not to trigger Kageura's Side Effect making their duels all the more thrilling for the former A-rank agent. Kageura went from addressing Yūma through epithets concerning his height to using his surname, while Yūma has taken to referring to him by his nickname "Kage" followed by th ehonorific -senpai.

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.

Kuniharu Kakizaki
Kageura and Kakizaki are presumably on good terms with one another, since they address each other by a nickname, with the Attacker even adding the honorific -san.

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.

Trivia

 * He likes sushi, grilled chicken, manga, and lazing around in the operation room.
 * In his first appearance Kageura was in a trion body with his casual clothes instead of his unit's uniform.
 * Although Kageura wears a mask to reduce the amount of skin exposed to his Side Effect, it was shown not to be hindred by clothing, at least when he is in a trion body.

 * Kageura was originally supposed to have the haircut that was eventually given to one of the "3 Idiots", and to be the top Scorpion user.
