The plot follows their partnership with bullied schoolgirl Lisa Mishima and detective Shibazaki as they unravel the past, with episodes detailing bomb threats, chases, and revelations about experiments on children for super-soldier purposes. Themes include cycles of violence, war trauma (atomic bomb echoes and 9/11 imagery), government corruption, youth alienation, and bullying, framed as a mystery thriller with personal drama and no lectures or identity-focused arcs.

Creator Shinichirō Watanabe cited influences from real Japanese politics under the Abe administration and a desire to spark youth interest in politics, but described it as entertainment reflecting personal feelings rather than activist ideology. Voice casting follows standard Japanese anime practice with no established-character alterations or live-action departures.

Reception included acclaim for its tension and score alongside some domestic pushback from right-leaning viewers over its critique of nationalism, but no modern progressive framing or backlash tied to DEI or identity politics. The narrative relies on classic conspiracy and coming-of-age tropes without embedding contemporary social justice elements as central drivers.
