Daisuke Gondō steps into the role of second captain for an elite defense team following his predecessor’s abrupt reassignment, clashing with members initially resistant to his loud, no-nonsense attitude and relentless training regimens. His stern exterior softens over time, revealing an unexpectedly brotherly rapport that contrasts the prior captain’s fatherly tone, slowly winning trust through unwavering commitment and tactical brilliance.

A tactician with sharp intuition, he uncovers threats like a monster lurking on Maroi Island by dissecting irregular seismic patterns, showcasing his analytical precision. Though unflappable in battle, he conceals a private dread of spectral forces, such as whispered Yuki-onna encounters, burying unease beneath stoic focus during operations.

When an alien empire launches a full-scale assault, he disregards command directives to chart Earth’s independent defense, secretly partnering with off-world rebels and deploying their gifted warship against the invaders. Leading frontline strikes on enemy bases and sabotage missions deep into hostile territory, his calculated risks fracture the empire’s foothold.

A pivotal moment arises when he puzzles out a teammate’s hidden duality as a fused human-alien entity—a theory proven only as they confront the empire’s warlord. His command during the climactic offensive shatters the invasion force, securing both Earth’s safety and an allied planet’s freedom.

His journey traces a shift from distrusting external saviors to championing interspecies cooperation, solidifying his belief that humanity’s survival hinges on unity with unconventional allies.
