Sara Tanjuro has recently transferred to Mikagami Eruma’s elementary school, quickly becoming the talk of the student body. Nicknamed “Satan,” Tanjuro boldly confesses his feelings to girls at every opportunity, a stark contrast to the shy and reserved Eruma. However, Tanjuro harbors a secret identity as member number 666 of Michaela, an organization that fuses technology with exorcism to eliminate angels who threaten society. As an anti-angel specialist, he conceals weapons within ordinary school supplies and dispatches supernatural foes with remarkable efficiency. Yet despite his prowess in battle, winning over girls proves to be a far more difficult challenge.
