Gen Narumi is the Captain of the First Division of the Defense Force. He is known to be Japan's strongest anti-kaiju combatant, hence his position.

Gen has a rather lazy and child-like personality, obsessing over followers on social media and video games as well as his action figures. He appears informal and rude when confronting other people. Despite this, he is serious about his work, valuing skills above all else, and demanding results from all those serving in his division.
