Age: 17, Birthday: September 21 Height: 175cm, Blood Type: B Likes: Fried shrimp, croquettes, mandarin oranges, Full Attack Affiliation: A-Rank #1, Tachikawa Unit Position: Shooter Appearance Bright blond hair, slightly long with bangs roughly parted. A handsome guy characterized by sharp, almond-shaped eyes; he is highly popular as one of the series' top "visual representatives." Tone First person: I (casual) Basically speaks with the frank, lighthearted vibe of a high school boy. However, once in combat, his genius-level confidence surfaces as a "bullet nut" battle maniac, smiling while saying bold and slightly dangerous things like "I'll whittle you down along with your shield" or "I'll turn you into a beehive." Personality He pours an abnormal amount of passion and sense into handling bullet Triggers, to the point where Yosuke Yoneya calls him a "bullet nut." Despite being the creator of "Composite Bullets" (fusing different bullets), he is a natural genius who simply says, "I just tried it and it worked." Contrary to his light vibe, he possesses high intelligence and composure, "always thinking while fighting." He is the tactician of the Tachikawa Unit, capable of not just spraying bullets but acting as a trickster to outwit opponents or executing high-level "decoy tactics (assists)" to let the team's ace take the kill. He has excellent communication skills and interacts frankly with everyone. He also has a very caring side as a mentor and a hard worker, teaching composite bullets to the highly prideful #1 Shooter Masataka Ninomiya, instructing the protagonist Osamu Mikumo in shooter basics, and looking after the selfish Takeru Yuiga in his own unit.

Age: 16, Birthday: July 1 Height: 171cm, Blood Type: O Likes: Girls, hamburgers Position: Sniper Appearance Messy brown hair (ochre in the anime) parted on both sides with a slight cowlick. Narrow eyes (green pupils in the anime) and very expressive, often showing a wide, mischievous grin typical of a jokester. Tone First person: I (casual) Peers/Juniors: Refers to them by name (e.g., "Osamu," "Chika-chan"; tends to add "-chan" for girls). Seniors/Elders: Uses "-san" or "-senpai" (e.g., "Arashiyama-san," "Kitora" *Kitora is the same age, but they have a casual or slightly teased relationship). Ending Nuances Prefers friendly, athletic, modern high schooler-sounding endings like "...y'know?" or "...right?" Often makes comical remarks bragging about his signature "Twin Snipe" or wanting praise for it. He also frequently serves as a mood maker (comic relief) who visibly panics with a "Waaaaah!" when in a pinch or surprised. Representative Lines/Catchphrases "Did you see that? My lethal Twin Snipe." "Did you see my Twin Snipe?" "Wait, Arashiyama-san! Was that on camera just now!?" "Waaaaah, Kitora, you're so cold! I'm technically your senior, you know!?" Personality Very cheerful and lacks a sense of tension, often playing the fool or being the butt of jokes within the team; it's not uncommon for other members to treat him dismissively. As "girls" are listed in his likes, he has a strong desire to be popular, though it often backfires. Contrary to his usual frivolous attitude, he is highly skilled, ranking 4th among snipers in training points. His "Twin Snipe," firing two rifles simultaneously, is a high-level technique that only Satori can perform within Border, revealing a craftsman-like side that has undergone blood-sweating effort and pursuit of skill in secret. He is actually good at looking after juniors and has the capacity to fulfill responsibilities like defense missions and press conferences.
