The premise frames his disability as the core mechanic enabling his unique combat style and the siblings' violent 'rehabilitation' journey through assassination contracts on a dystopian island filled with genetically enhanced gangs. This setup is entirely organic to the manga's action narrative, with no source-material alterations or external mandates.

The wheelchair-based combat serves as a genuine advantage within the story's rules rather than a vehicle for messaging, keeping the focus on visceral shonen-style action and family-driven motivation. Sister Shizuka functions as the broker and caretaker who secures the assassin jobs, underscoring sibling bonds as the central relationship without any identity-based framing or lectures on systemic issues. The series uses a standard Japanese voice cast and original characters in a violent premise that avoids race or gender swaps, LGBTQ elements, or oppression themes. This results in a low woke score because the disability element integrates directly into the combat fantasy without ideological intrusion, preserving the entertainment value of the core assassin plot.
