Beck, a genetically enhanced Nanorace human with moisture-sensitive nanomachines, wields the volatile "Red Ash" ability to dissolve and reshape his body into ash—a skill offset by his desperate goal to erase his enhancements and gain acceptance within the oppressive Purerace society. Partnered with Tyger, a gentle giant, he hunts interdimensional Magicicadas for profit, their bond strained by grief over Lucy, their former teammate whose fatal nanomachine failure left Beck guilt-ridden and habitually memorializing her through small gestures like ordering her favorite meals.

Their precarious routine fractures when Call, a fugitive pursued by mercenaries Safari, Stripe, and Deny, intrudes on a mission, claiming echolocation skills identical to Lucy’s. Beck’s initial hostility shifts as Call’s tactics prove indispensable, forcing him to collaborate despite distrust. Their uneasy alliance hardens into mutual dependence when she shields him during a lethal showdown, mirroring sacrifices he once witnessed.

Escaping a high-tech facility, Beck confronts Lucy’s unexpected survival, unraveling assumptions about her death and exposing hidden ties between parallel worlds. Trapped in a sterile complex with allies, he grapples with systemic persecution’s scale while his priorities fracture: self-preservation clashes with loyalty to Tyger and Call, tempering his abrasiveness without erasing his hunger for a normal life.

His journey—from solitary profit-seeking to protective leadership—threads through technological exploitation, redemption, and the cost of belonging, leaving interdimensional consequences unresolved as he balances sacrifice and survival.
