Kyou kara Watashi no Akuma-san!

Hina is a high school girl who has just lost her grandmother, who was her only family and guardian. In order to fulfill her grandmother's last living wish to see Hina dressed as a bride, Hina sneaks into the church on the night before the funeral… A romantic comedy between a no-nonsense demon and a sheltered girl unfolds.
