You're Being Summoned, Azazel

The second season of Yondemasu yo, Azazel-san.

The great detective Akutabe has an assistant, Rinko Sakuma, who is trying to learn to summon demons. This is the story of her misadventure when she actually manages to summon 2 demons unexpectedly.

When demons walk the streets, the cops need to recruit more demons! In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace. Enter the Hiizumi Life Counseling Office, a fantastic foursome of unique teenagers, each gifted with an amazing super power! Since it sometimes takes real demon-fire to fight demon fire, the first three quarters of the team aren't exactly human: Ao, a cat-eared telepath; Kotoha, a half-human conjuror; and Hime, descended from a dragon (and the town's acting mayor), all of whom also happen to be delightfully female. Rounding out the group is the token male and human, Akina, the office director and "Oyakume," capable of banishing spirits permanently (and from their point of view quite fatally) via a process called tuning. They may not look as impressive as some other superhero teams, and they certainly don't have the most dynamic name ever, but come hell hounds or high water, but they will defend their city!

Adapted from the 2005 adults-only superhuman battle action visual novel game Ayakashi. Ayakashi is a parasite life force that gives superpowers to its host, taking in return the host's entire life force. Kusaka Yuu is a student that lost his will to live after the death of a dear childhood friend, until the day a mysterious girl, named Yoake Eim, appears. From that moment on, his life would never be the same again. Hunted by Ayakashi and their hosts, the power within Yuu awakens and a never ending battle begins.
