Trama

Sara Tanjuro, nicknamed Satan, transfers to Mikagami Eruma's elementary school, quickly gaining a reputation for boldly confessing his love to girls, a stark contrast to the shy Eruma. Unknown to his classmates, Satan leads a double life as a member of Michaela, an organization that uses a blend of technology and exorcism to combat angels causing chaos in the world. As member 666, he is an anti-angel specialist who cleverly disguises his weapons as ordinary school supplies, allowing him to effortlessly defeat supernatural beings.
