Himegoto Masquerade ~Ojousama-tachi no Tawamure~

Shizunari Itsuki has no relatives, lost his memories, and even suffers from a fear of women. To overcome this phobia that causes trouble for his adoptive family, he enrolls in Saint Tiphereth Girl's School disguised as a girl under the name Shirahane Itsuki. However, his hopes for a quiet school life are shattered when model student and school star Hirasaka Eri, known as the 'Holy Mary,' discovers his secret. Luckily, he also uncovers her true nature, and they strike a mutually beneficial pact: keep each other's secrets and support one another. To help him conquer his gynophobia, Eri offers, 'I, Hirasaka Eri, offer you my body.' She helps him get used to seeing and touching a woman's body, but this must remain another secret. Yet his problems don't end there. As he spends time with the famous 'Holy Mary,' other girls grow jealous, making him many enemies. Then another girl, Mitsurugi Maya, known as 'Arthur' and head of the school's disciplinary committee, The Chivalric Order of the Church, vows to protect him. 'Don't worry, Itsuki, I'll keep you safe!' With Eri and Maya competing over him in a clash of charisma, the school splits into two factions. With all eyes on him, can Itsuki achieve the goal he came for?
