Eric, a temperamental Tokyo teenager with a fierce aversion to romance, finds his solitary life upended when his anthropologist mother shares a family photo during her research on a tribe practicing pattern magic. This act provokes the tribe’s leader, Nima, to abruptly arrive in Tokyo, proclaiming herself his bride—a role he angrily rejects. His combative nature fuels clashes with authority figures and peers, particularly class president Lisa, whom he views as intrusive. Nima’s relentless attempts to bond through magical disruptions and culturally unfamiliar gestures spark chaotic, comedic encounters, though Eric rebuffs her advances, distrusting emotional connections.

The unresolved tension between his modern urban existence and Nima’s tribal customs reflects his mother’s unilateral involvement in the arrangement. Tribal rituals, including symbolic tattoos, intermittently disrupt his routine, though he dismisses their cultural weight. While fleeting moments of humor emerge from Nima’s social missteps and his blunt retorts, Eric’s resistance remains steadfast, with no narrative indication of lasting change in his defiant demeanor.
