19 years old (University student) Birthday: April 29 Blood Type: B 173cm (CV: Katsuyuki Konishi) Likes: New menu items at restaurants, soccer, eggplant curry Captain of the B-Rank #4 Ikoma Unit, Border Headquarters. Position: Attacker First person: I (casual, rough) A cheerful Kansai native who is completely at his own pace, with his head full of "girls" and "delicious food." He's always grinning and never gets angry. A festival-loving guy who puts all his energy into entertaining those around him (or enjoying himself). He shows no desire to flaunt his authority or pride as a captain. It's precisely because of his approachability and his broad-mindedness—remaining unfazed no matter what is said to him—that the Ikoma Unit is the most homey and close-knit team in Border. He is Border's premier user of Kogetsu. Often called by the nickname "Iko-san." A skilled cook. Originally from Kyoto. Appearance: Black hair in a stiff-looking slicked-back style. A man with sharp, thick eyebrows and downturned corners of the mouth, featuring a distinctively rugged face. He wears goggles during combat.

He has sanpaku eyes that give him a rather sharp, unfriendly look, and while he is expressionless, he's actually a decent guy with a clean-cut face. He wears goggles around his neck during combat. He aimed to be a professional shogi player until midway through middle school and is the strongest in Border when it comes to shogi. Originally from Osaka.

16 years old High school freshman Class 1-A at Mikado City First High School Height: 170cm Birthday: November 7 Member of the B-Rank #4 Ikoma Unit, Border Headquarters. Position: Attacker Likes: Scallops with cheese, Salisbury steak, and stuffed peppers. A pure "mood-maker/extrovert" personality who is always bright and easily gets carried away. He has a comedic streak that rivals his seniors in the Ikoma Unit. He is very lighthearted and has a habit of making groundless bluffs with a smile. He boasts that he watched combat data "20,000 times!" (though Satoshi Mizukami calmly retorts, "It was 20 times at most"). He talks big, saying things like "I'll stop them" regarding high-priority targets. He's the type whose mouth runs ahead of him, leading to the routine of being mercilessly scolded by the operator, Mari, with shouts like "Liar!" or "Shut up for once!" Rather than carefully constructing a plan, he is the intuitive, headlong-rush type driven by the momentum of the moment. He's thick-skinned enough to brush off failures with a lighthearted "tehe-pero." He ends his sentences with "-ssu" or "-su." Example: "Whoa, Iko-san! That was amazing-ssu!" "Whoa, for real-ssu?!" Appearance: Blond hair and green eyes. (CV: Shun Horie) The only team member originally from Mikado City.

Operator of the B-Rank #4 Ikoma Unit, Border Headquarters. Affectionately called "Mario" by the team members. While she has a tomboyish, frank "reliable mom" vibe, she is also very maidenly and bad at taking compliments. She has a kindness that is the same inside and out. She manages the team stoutly. She provides sharp retorts in a rhythmic Kansai dialect. Originally from Hyogo Prefecture. The mother figure of the unit. She has boyish, spiky hair and purple eyes. Contrary to her appearance and blunt way of speaking, she has a very feminine side. She is very caring. Likes: Flowers, cute things
