Kagami no Kuni no Ohime-sama ga Gakuen Seikatsu to Koi o Hajimemashita

At the end of summer vacation, Takuma snuck into Hinoura Gakuen at night with his osananajimis Iku and Masato, and best friend Reiko. They planned to investigate one of the school’s seven mysteries about a ‘disappearing shadow’ and also do a courage test at the same time. Reaching the large mirror which was the source of the rumours, they deemed that it was just a normal mirror and there was nothing strange about it. However, when Takuma touched the mirror, he was sucked inside it.

When he came to, he found himself in an unfamiliar place with an unknown girl knocked down in front of him. She was the princess of the Aquaknight Kingdom, Sara. She had wished to go to Takuma’s world, on the other side of the mirror. He sympathized with her having her future pre-determined by others since he had also experienced this in his past. After that, she came to live at his home since he had a strong desire to help her out after seeing her crying and vowing to be able live by herself.
