Ryoichi Kyogoku, a time traveler from a future lunar colony where Earth’s environmental collapse forced humanity’s exodus, operates under a critical mission: awaken latent psychic abilities in select individuals to rebuild his timeline’s dwindling population and prevent psychic-human extinction. Calm, pragmatic, and effortlessly charismatic, he infiltrates a junior high school, charming students and staff alike while covertly testing candidates. Those who fail vanish without trace—a necessary sacrifice for his cause.

Initially enigmatic and rigidly duty-bound, his worldview fractures upon witnessing Earth’s lingering beauty and forming genuine bonds, particularly with Kahori Harukawa, a non-psychic classmate. Their growing romance clashes with his mission, sparking moral conflict as he grapples with the ethics of manipulating lives. This introspection intensifies when confronting Kenji Seki, a rival-turned-ally whose sealed powers and familial history—Kenji’s grandfather once opposed Ryoichi’s parents—force uneasy collaboration.

A haunting revelation reshapes Ryoichi’s understanding of sacrifice: his Shiba Inu familiar is his father, transformed into a guardian entity to protect him. This truth, paired with Kenji’s selfless intervention during a life-threatening confrontation, fractures his ideological resolve. Choosing empathy over duty, he abandons his mission, departing with Kenji to their shared future. A post-credits tease implies his story remains unfinished, leaving room for return.

His arc weaves duty, morality, and the transformative power of human connection, charting a path from detached operative to a man reshaped by love, loyalty, and the weight of unintended consequences.
