Description
Yasubee "Yasu" Morozumi, codenamed Odin, serves as the self-proclaimed "chief soldier" of the secret organization Zvezda, though his actual rank is low, comparable to junior members like Dva. His uniform includes the standard Zvezda mask for lower ranks, augmented by a jacket and hat featuring subtle cowboy-themed elements.

Personality-wise, Yasu is a dandy youth fixated on appearances and cultivating a "bad-boy" image, primarily through his persistent cigarette habit – a core aspect of his identity symbolizing his desire to project maturity and machismo, though it often manifests as childish posturing. This habit causes resentment among fellow members. His loyalty to Zvezda stems more from fear of leader Kate Hoshimiya than ideology, making his allegiance easily swayed by perceived greater threats. He frequently displays cowardice, avoiding conflict or fleeing troublesome situations despite attempts to appear formidable.

His background identifies him as a former gangster who operated under Goro Shikabane (General Pepel) before both joined Zvezda; Yasu retains deep respect and fear towards Goro from their mentor-protégé past. Within Zvezda, he often irresponsibly misuses technology created by Natasha (Professor Um), causing recurring mishaps that compound his reputation for incompetence. His relationship with Asuta Jimon remains neutral.

Yasu acts as a recurring source of instability. During Kate's anti-smoking campaign, his addiction and identity conflict drive him to temporarily betray Zvezda, siding with persecuted smokers. Fear of Kate ultimately forces his return. After years of perceived uselessness and enduring verbal abuse, he betrays Zvezda again for financial gain, aligning with the antagonistic Tokyo Governor (Asuta's father) during the organization's crisis. In this arc, he acts as a toady to the Governor while scheming to claim personal glory, though these plans collapse. Following the Governor's defeat, he comically attempts to reintegrate into Zvezda, facing only light punishment – primarily denial of dinner for an extended period – indicating his easily forgiven status despite repeated disloyalty.

His character functions largely as comic relief through his failures and hypocrisies, embodying the "Butt-Monkey" archetype.
