Kouto Onmyou Gakkou: Kizumono no Hanayome Gaiden

The Imperial Capital Onmyo School is a prestigious three-year boarding institution that trains students for the Imperial Onmyo Bureau, a national organization dedicated to exorcising demons. At the school, Yakou, Kazunari, and Reiji are second-year students who find themselves entangled in a crisis when Reiji is on the brink of expulsion due to his involvement in a confrontation with the son of a military official. In a desperate bid to help Reiji, Yakou and Kazunari attempt to appeal to the headmaster, but their efforts are met with an unexpected condition: they must investigate and capture a mysterious masked man known as Semimaru, who has been terrorizing the upper class with his attacks. This development sets the stage for a complex and intriguing narrative, as the trio embarks on a perilous mission to uncover the truth behind Semimaru's identity and motivations.
