Go Mutō, a seven-year-old of Japanese and Filipino descent, sports medium-length brown hair, thick eyebrows, and olive skin. Born to Koichiro, a Tokyo construction worker, and Mari, a retired Philippine competitive swimmer, he spends hours immersed in online gaming, fueled by ambitions to join Olympic e-sports and migrate to tech-forward Estonia.

When a devastating earthquake strikes Tokyo, flying debris gashes Go’s eyelids, leaving his eyes bloodied. Rescued by Nanami Miura, he’s bandaged and escorted to a hillside shrine. Koichiro diagnoses the superficial cuts, crediting Go’s gaming-honed reflexes for evading graver injury. With a stapler, he seals the wounds—a crude fix leaving piercings-like scars.

Amid chaos, Go’s digital savvy surfaces as he messages a gaming ally, whose westward safety tip steers the family’s escape amid conflicting disaster reports. After an unexploded bomb kills Koichiro, Go, his sister Ayumu, and surviving relatives press onward, balancing grief with survival. Adrift on a dinghy, Go trades morbid quips with Ayumu, masking despair with wit.

The Mutōs ritualize memory through photographs, framing Go in snapshots that chronicle their odyssey. His dual heritage and e-sports dreams thread through their trials, anchoring themes of identity and perseverance. His name, 剛 (“strength”), and surname Mutō (武, “military”; 藤, “wisteria”) mirror his resilience and the familial ties strained yet sustained through catastrophe.
