Tatsuhito Ikoma

"Dude, it's tuna! And it's a cutlet! In a bowl of rice! No way it ain't tastin' good, dammit!"

- Tatsuhito Ikoma to Kōji Oki

Tatsuhito Ikoma is the no. 6 Attacker and the captain of Ikoma Unit.

Appearance
Ikoma is a light-skinned young man of average build. He has green eyes, an aquiline nose, and a square jaw. He wears his messy, medium-length black hair slicked back.

Ikoma's uniform is comprised of a vermillion, white-zipped jacket. A horizontal white line runs across the chest portion roughly at the height of his armpits, whereas on the back it bends into a flat V-shape pointing downwards, with an ornamental button right above the tip. On the right breast, the white line encircles Border's logo, above which is emblazoned the B-rank emblem. Everything above the white line is black in color, including the high collar, which Ikoma keeps open to reveal a round-collared undershirt; the only exception are the vermillion plain button epaulets. The sleeves are also black until roughly halfway through the humerus, after which they turn vermillion, and disappear into Ikoma's thick gloves about an inch past the elbow. The gloves are black with a gray palm and a thin brown buckle that encircles them near the cuff. The black portion of the sleeves and the collar bear a square motif that suggests padding. The uniform is completed by black pants with front and back pockets, gray-brown boots that reach halfway up Ikoma's calves, and a pair of rectangular goggles with protruding lenses and a vermillion strap which he wears at all times during combat.

Personality
Ikoma has an odd personality. He particularly likes being flashy on camera. He also enjoyed teasing Hosoi by calling her cute. He also seems to disregard battle strategies entirely, as he spent the whole time talking about girls he found cute and the new cafeteria menu instead of preparing for their upcoming battle. In order to further impress girls, he started practicing the guitar in secret, but he doesn't know when to reveal that, so he is considering switching to cooking. He also refused attacking Chika, worried that it would make him seem evil.

Satoshi Mizukami
Ikoma and Mizukami appear to be friends. Despite his pragmatism, the Shooter listens to Ikoma's rambling anecdotes attentively, often providing humorous commentary on or a grounded reaction to them and his outlandish behavior. Despite being the captain, Ikoma relies on Mizukami's tactical insight during rank battles, although when multiple paths are open the Shooter lets the Attacker decide which one to pick before focusing on how to achieve it himself. Mizukami addresses Ikoma by his nickname, to which he happens the honorific -san.

Kōji Oki
Ikoma and Oki appear to be on friendly terms. The Sniper is amused by his captain's puzzling anecdotes and makes light-hearted remarks on them, or, more precisely, on Ikoma's choice of subject and storytelling habits. Ikoma often comments on Oki's popularity with girls despite the latter's denial, even using his good looks as an argument to get him to shoot Chika, to Oki's embarrassment. There might be a shade of envy to his teasing. Ikoma believes his professed reluctance to snipe young girls to be no more than an act to support his "good guy" façade. He addresses Oki by his surname, without honorifics, while the Sniper uses his nickname followed by the honorific -san.

Maori Hosoi
Ikoma's nonchalance before a rank battle can unnerve for Hosoi, as instead of strategizing he ends up sharing rambling anecdotes whose pointlessness can leave her astonished to this day. Despite doing so for all girls, Ikoma had never called Hosoi cute until Oki pointed it out, prompting the Attacker to rectify his omission multiple times, to her embarrassment. he calls her by her nickname, to which he appends the suffix -chan.

Kai Minamisawa
Minamisawa appears to greatly admire Ikoma or anyway to seek to win his approval, as many of his excessive shows of enthusiasm follow one of the captain's statements. Ikoma appears to be his only teammate who does not react to them coldly. He refers to Minamisawa by his first name, without honorifics.

Yūichi Jin
Ikoma and Jin are of an age and part of a group of 19-year-old agents who hang out together. Ikoma is awed by Jin's combat ability and jumps at the chance to spar with him, watching his matches when he is already fighting someone else. Ikoma refers to Jin by his surname without honorifics, whereas Jin uses the diminutive nickname "Ikomacchi".

Jun Arashiyama and Kuniharu Kakizaki
Ikoma is of an age with Arashiyama, Jin and Kakizaki, and they regularly end out together. Like Jin, Ikoma has a tendency to be irresponsible on their outings, and the two prompt Arashiyama to goof around with them, forcing Kakizaki into the role of the voice of reason.

Shinnosuke Tsuji
Ikoma holds Tsuji's combat prowess in high esteem. Since the latter does not appear to be bothered by Ikoma referring to him by his surname followed by the diminutive suffix -chan, the two are presumably on good terms.

Noboru Koarai
Koarai and Ikoma are presumanly on good terms, with Koarai feeling entitled to bemoan Ikoma's involuntary foul when he sparred with Hyuse. Koarai addresses Ikoma by shortening his surname and appending the honorific -san, while Ikoma uses Koarai's nickname and no honorifics.

Yūma Kuga
Ikoma is deeply impressed with Yūma's combat prowess, and particularly with his victory against Kō Murakami in round three. Yūma has complimented Ikoma's skill after being defeated by him in round six.

Hyuse
Ikoma is impressed with Hyuse's swordsmanship and was thrilled at the prospect of challenging him. His admiration has only grown over time. He apologized to him after unwittingly breaking the rules in their match and contributed to Hyuse's maturing respect for Border's swift progress. Hyuse refers to Ikoma by his surname, without honorifics, while Ikoma uses his first name, also without honorifics, although it is unknown if, as part of the Neighbor's cover, it was made into his first or family name.
