OPERATION COZY FAMILY. 
Thousands of years ago, Enka the God of Destruction, was killed. However, with a dying breath it claimed that its child would appear and destroy humanity. Now in futuristic Japan, all of the potential children of Enka have been found and placed into a haphazard family. 
Teika the lion, Gekka the jellyfish, Yuuka the oni, Ginka the cross-dressing mafia son, and Hyouka the bioweapon--along with their parents Ouka and Kyouka (the ruler of a demon underworld)--all live under one roof in a family frenzy.

A Japanese voice actor. She's also a certified junior and senior high school teacher.

Hirohashi was born in Niigata Prefecture, and her family's home was a Buddhist temple. Because of this, she attended Ryukoku University in Kyoto, a Buddhist university. In the middle of her first year, however, her parents told her that she could do what she liked, even if it wasn't related to Buddhism, so she sought out what she wanted to do. During her second year, she remembered a radio show she used to listen to in middle school and became interested in voice acting, so she started going to the Aoni Coaching School Osaka while attending university at the same time. The radio personality she had listened to in junior high school was a voice actor, which inspired her to become a voice actor herself.
