Description
Seimei Usami, a solitary 12-year-old with sharp blue eyes and short blonde hair, sports mismatched ear piercings—black on the left, white on the right. His wardrobe leans militaristic: a dark green shirt emblazoned with a fanged open-mouth design, a black baseball cap, long green pants, and sneakers, often accompanied by a black mask obscuring his mouth. Childhood betrayal by teammates in a Bottle Royale left him distrustful and averse to collaboration, his trauma triggering physical unease at the sight of close friendships. Though he begrudgingly joins forces with Ryo and Cota during a match, his hyperfocus on Chance Targets leads to their swift elimination.
His control-type Bottleman, Lifleguardiwan DX, mirrors the Canes Venatici constellation with a green-and-yellow base accented by purple highlights. Designed around a hound motif, its Star Beast Armor aligns with Seimei’s canine metaphors. The dual-barreled weapon—a short barrel for trajectory adjustment and a long one for precision—executes its signature Hound Strike.
Once a double agent for Machiko Hocari, he abandons her upon witnessing her manipulation of Ryo, which triggers Ryo’s emotional spiral and inadvertently wounds him. This choice highlights his rigid ethics, rejecting Machiko’s tactics despite their history. After recovering, he allies with BMA supporters to counter B-DACT and Team Citrus, aiding in interrogations and infiltrating BMA’s AI-compromised headquarters.
In the Bottle King deciding match, he faces Cota in Gate 4, dominating until Cota unleashes Sparkling Nova. Defeat doesn’t sour him; he acknowledges Cota’s progress and later verifies his and Ryo’s survival post-AI facility explosion. His arc closes as he watches their final showdown alongside former rivals, signaling tentative steps toward reconnection.
Passive-aggressive and quick to mock—dubbing Ryo "rich boy"—his barbs veil latent concern. Though he gradually embraces cautious trust, he remains critical of flawed systems, openly challenging Citrus’s tournament plans for unfair rules.
Beyond battles, he owns a pet dog, and his name derives from "Lifeguard," a Japanese soda brand. Lifleguardiwan DX’s name fuses "lifeguard," "rifle," "guardian," and "wan" (a Japanese bark sound), cementing his canine-themed identity.
