Manami Miwasaka, a first-year Oumidai Academy student, joins the Astronomy Club—a covert team of supernatural operatives opposing interdimensional predators called Light Hunters. Her Kotodama magic enables precise manipulation of emotions and behaviors, frequently channeled through MDs, crystalline spellbooks that amplify her incantations during combat.

Open-hearted and trend-obsessed, Manami’s animated demeanor makes her inner world easily legible to peers. She thrives on tokusatsu lore, anime marathons, and club missions, integrating swiftly into the group’s perilous operations.

A defining trial occurs when she infiltrates the memories of an arsonist connected to Light Hunter atrocities, enduring visceral flashbacks of the woman’s exploitation and torment. This psychic intrusion provokes a retaliatory assault: a nightmarish insect horde engulfs Manami, scarring her psyche and body.

Subsequent dangers escalate when rivals abduct her during a school festival, deploying psychological torture until allies stage a rescue. These harrowing experiences juxtapose her fragility against her refusal to abandon the fight, even as missions grow riskier.

Her relationships with teammates like Ryou Hamura and Makoto Kedouin oscillate between earnest support and rash decisions, reflecting her duality as both stabilizer and wildcard. Across narrative iterations, her arc traces a trajectory from wide-eyed recruit to battle-tested operative, with Kotodama serving as both weapon and narrative catalyst—twisting adversaries’ emotions while exposing her to the moral ambiguities of supernatural warfare.
