Now, this is the closest I could find to your description:
Yami No Matsuei- Tsuzuki Asato is a 26 year old, happy-go-lucky, and dorky shinigami (god of death) whose job is to makes sure that those who are dead remain dead and stay in their proper realms. Even though he's had this job for over 70 years, he is in the worst division with horrible pay. He also has a knack for not keeping partners (since shinigami work in pairs), but now he seems to have one that will stick around; stubborn, smart-mouthed, serious and defensive 16 year old, Kurosaki Hisoka. With each case they investigate, they come closer to the conspiracies of the serial killer Dr. Muraki Kazutaka. Tsuzuki's relationship with Hisoka is growing stronger and closer...but there is a dark past to how Tsuzuki died that will not give him peace.
Here is also a couple of others with magic involved:
Fairy Tale
Mahou Sensei Negima
Omamori Himinari
Amaenaideyo- This guy's powers are awakened, by stripping a girl just enough to see her in a erotic manner, to transform into a super monk that can perform mass exorcisms. He is a buddhist priest in training that possess the power of the legendary buddhist; seizen (not sure of spelling). He travels in a group of 7 female nuns to send spirits that has not passed to the afterlife.
There's a couple more on my mind but I can't remember the names. I'll get them later if these aren't it.
