Name: Saki Kusakabe * Age: 15 * Birthday: February 9 * Height: 153cm * Blood Type: B * Zodiac: Rana * Affiliation: Border HQ * Unit: A-Rank #4, Kusakabe Unit * Position: Captain & Operator * Likes: Data analysis, mystery novels, shrimp gratin, soy milk hot pot Despite being an A-rank captain, she is a 15-year-old middle schooler. She serves as the Operator. Extremely calm, assertive, and analytical. Even though she has older members in her squad, she gives orders and opinions as a captain without hesitation. She has almost no reservations about age hierarchy. Originally a Gunner. She was in the same recruitment class as Ai Kitora, but after failing to beat Kitora, she switched to being an Operator. Her skill as a combatant was also said to be quite high. Speech Style: "I believe that is incorrect." "Isn't that judgment a bit premature?" "...Well, I suppose so." "I think it would be better to do it this way, though." "I won't necessarily object." Squad Composition: * Shun Midorikawa (14) -> Attacker * Ryuji Saeki (17) -> All-Rounder * Kazuma Satomi (17) -> Gunner * Hayato Uno (17) -> Sniper As a unit, they utilize high mobility to strike weak points in defenses. She manages them as both Operator and Captain. "Small, twin-tails, sharp eyes, 15 years old, A-rank captain, analysis freak, former combatant, leading 4 boys." She calls Saeki "Ryuji" even though he is older. Currently, her squad is ranked one step higher than the Arashiyama Unit (which Kitora belongs to), so she has successfully achieved her revenge. Suwa looked after her during her combatant days, and she respects Osano (Suwa Unit Operator) and Kesshio (Katagiri Unit Operator), who helped her when she transitioned to being an Operator. She is probably stronger than Rokuro. Member of the Kitora Victims Club.
