Kaito Fūjin, a student at Kamui Daimon Comprehensive Academy, commands Jenock's Fifth Platoon. His light skin and teal eyes contrast sharply with indigo hair styled in uneven loose braids, fastened by green and white bands tipped with white fur-like accessories. Towering over classmates, he wears the Jenock navy uniform precisely buttoned with its yellow tie. Born into poverty, Kaito nurses profound resentment toward affluent peers like Gendou Isogai, viewing their privilege as unearned comfort. This fuels his relentless ambition for advancement, driving him to treat academy missions and point-gathering with fierce intensity. He openly derides those he considers unserious: dismissing Arata Sena for treating LBX battles "like a game," branding Rikuya an "escaping coward," and mocking Gendou as a "rich little master." Official records note his fastidiousness, narcissism, and tendency toward obsessive focus. Initially piloting the DC Braver LBX as platoon leader, Kaito later inherits the purple Val Sparos from Hikaru Hoshihara, arrogantly dismissing Hikaru's guidance. After aligning with World Saber, he equips it with Riding Armor before its destruction by Dot Blastrizer G-EXT. Strategically capable, he directs his platoon to target structural pillars during Operation Destroy Gigant Wall. Though coveting command in Operation Capture Blackwind Canyon Camp, he grudgingly defers to Gendou’s tactical plan. Societal inequality shapes Kaito’s disillusionment. He debates Seredy Kreisler’s lectures on wealth redistribution and global unity but voices skepticism about their feasibility. Daigo Koumoto’s interrogation during the Air Fortress Dol Garuda Ambush further fractures his convictions. When Seredy seizes Kamui Daimon and recruits for World Saber, Kaito defects from Jenock, justifying his betrayal as necessary for systemic upheaval. He openly rescues Phantom with Val Sparos, directly confronting World Allied Forces. His dynamic with Fifth Platoon sharpshooter Tadashi Fukino reveals complexity. Kaito pressures Tadashi to overcome trauma from accidentally destroying a friend’s LBX, demanding during Eldar City Garrison Duty, "When are you going to stop fussing over little things?!" He visibly swells with pride when Tadashi succeeds. After Kaito’s defection, Tadashi voices fears of facing him in battle and insists on retrieving him, reflecting mutual investment. Kaito vanishes after Val Sparos’ destruction but later emails platoon mechanic Bunta, acknowledging his teammates’ emotions—prompting Tadashi’s relieved joy. His status shifts to "LOST" following his World Saber allegiance.
