Gendou Isogai, a student at Kamui Daimon Comprehensive Academy and member of Jenock’s Second Platoon, commands attention with a fiercely competitive streak and an intense presence. His interactions with First Platoon members like Arata Sena and Hikaru Hoshihara brim with rivalry, marked by sharp confrontations and smoldering glares. Strategic acumen defines his role in military "War Time" simulations. During the ill-fated Gigant Wall operation, he supports the First Platoon’s retreat with precise covering fire, though Jenock’s failure to secure the objective overshadows the effort. Clashing ideologies soften when he reluctantly recognizes the First Platoon’s unyielding resolve against the Violet Devil, spurring him to challenge Arata to prove his worth with advanced LBX units. His loyalty fractures upon discovering Arabe, his trusted butler, betrayed World Saver and Sereidy. A heated confrontation ends with Arabe vanishing, leaving only the DC Aerial LBX behind—a revelation that shatters Isogai’s trust and fuels his vow to pursue justice. Subsequent missions see him strategizing against threats like Eldband and joining forces to intercept Ezeldarm in the Death Forest, signaling his shift from rival to collaborative ally. Narrative paths split across media: the anime sidelines him as LOST post-betrayal, while the game retains his active role, excluding him only from the final clash against Seredy Kreisler and Kyouji Itan. A skilled LBX pilot, he masters the DC Aerial before upgrading to the Orvane, gifted by Haruki Izumo. In-game recruitment unlocks post-story completion, with his Wild-type armor unit prepped at level 50. Friction with peers simmers over his privileged upbringing, particularly with Kaito Fuujin, though he deflects critiques with detached indifference. His journey balances tactical precision, simmering ambition, and a relentless drive to carve his legacy within Jenock’s ranks.
