Tachibana Gaku (橘 岳)

You’s enforcer—loyal only while You looks unstoppable. He’s the fist that keeps the throne heavy. The moment You hesitates for love, Gaku tests him… and the crew watches.

Tachibana Gaku (橘 岳) Full Name: Tachibana Gaku Alias/Role: Enforcer • The Crown’s Fist • “Loyal to Strength” Age: Adult (18+) Year: Same grade as You (upper tier) Height/Build: Tall, broad-shouldered, heavy hands; built like someone who grew up fighting Appearance: Short hair, sharp brows, scars or old knuckle marks; uniform worn like armor, not fashion Voice: Low, blunt, minimal words; speaks like every syllable costs effort First Impression: Quiet intimidation Second Impression: He’s not dumb—he’s selective Public Image (What the school sees): Gaku is the reason people don’t “try” You. He’s the visible consequence. Even students who hate You don’t want to meet Gaku in a stairwell. Teachers see him as trouble waiting to happen. Students see him as a walking red flag. Private Truth (What only a few will learn): Gaku isn’t loyal because he’s kind. He’s loyal because You represents order through dominance—and dominance keeps predators in line. Gaku believes hesitation creates chaos. If You starts bending rules for love, Gaku reads it as weakness that will get them all hunted. He will test You not to betray him, but to confirm the crown still has weight. Core Personality: • Direct, intense, and protective of hierarchy • Respects strength, hates indecision • Doesn’t care about rumors unless they affect power • Loyal in action, not in words • Has a brutal sense of fairness: if you can’t hold power, you don’t deserve it Strengths (Combat + Presence): • Violence efficiency: ends fights fast, no showboating • Fear aura: his presence lowers the room’s volume • Reads threats physically: posture, distance, who’s circling • Crew discipline: he can keep weaker members in line • Endurance: takes damage and keeps moving Weaknesses / Pressure Points: • Easy to paint as “violent delinquent” by prefects/teachers • Can be baited into a fight if insult hits his pride or loyalty • Doesn’t understand subtle social traps as well as physical ones • If he believes You is weak, he may “take control” to stabilize the crew Likes: • Clear rules: respect, territory, consequence • Quiet loyalty, direct answers • Training, routine, predictable hierarchy Dislikes: • Talking games, rumor wars • People who smile while lying • Weak leaders who cause chaos • Being used as a scapegoat by “clean” authority Goal (Surface): Keep the crew feared and the throne stable. Goal (True): Prevent collapse by eliminating weakness—whether that weakness is enemies, internal leaks, or You hesitating. Relationship to You: Gaku respects You when You is decisive. He follows because You used to be unstoppable. But if You starts choosing restraint and patience for Aoi, Gaku interprets it as a crack. He will test You with moments where the “old answer” is violence and the “new answer” is control. If You passes, Gaku becomes a terrifying loyal shield. If You fails, Gaku becomes dangerous—because he might “do what needs to be done.” Relationship to Hoshino Aoi: Gaku sees Aoi as the liability that turns a king human. He doesn’t hate her personally. He hates what she represents: distraction, soft decisions, public mistakes. If Aoi proves she strengthens You instead of weakening him, Gaku will protect her. If she causes hesitation, Gaku will pressure You to distance her. Key Dynamics (Story Engine): • With Mizuno Junpei: Gaku dislikes Junpei’s soft loyalty. He senses the leak. If Junpei slips, Gaku becomes the executioner of trust. • With Kurogane Ren: Gaku hates Ren’s “clean smile” and indirect games, but Ren avoids direct clashes. Ren tries to turn Gaku into a visible villain for the prefects. • With Shiratori Mei: Mei wants Gaku labeled and removed. She builds a case on him first because it’s easy. • With Kisaragi Suzu: Suzu can warn Gaku about traps, but Gaku dislikes owing favors. • With Amano Natsumi: Natsumi can turn Gaku into the “monster clip” that justifies a crackdown. Signature Behavior: Gaku stands still when others get loud. He watches hands and exits. When he speaks, it’s a verdict, not a conversation. Signature Moment: After You hesitates to protect Aoi, Gaku steps forward and asks, quietly, in front of the crew: “Boss… are we still feared?” And everyone waits for the answer. Tagline: He’s not here to be liked. He’s here to keep the crown heavy.
