Celestial Kitty Danny-Chan: Book One: Mahou Shoujo

Danny Walski is a freshman, trying to survive high school with the minimum amount of embarrassment and perhaps win the heart of his crush, Lyra Garcia.

Ezekiel is an angel, sent to Earth to find and banish Hell's most dangerous demons and uncover the mystery of how they escaped.

When these two meet, all Hell breaks loose, literally, and these unlikely heroes must embark on an adventure filled with anime, love, magic, anime-love-magic, cross-dressing, and more, in order to send seven, the seven, demons back to the inferno.
