Hīragi Family

The Hīragi Family is the most powerful clan in Japan and are the current leaders of the Japanese Imperial Demon Army. They manage to control the JIDA through its family members, occupying all the top positions in the JIDA and are strong fighters. However, this leads to power struggles which causes discomfort among its members, particularly Guren and Shinoa. The family is noted as "scary" by many, including Mitsuba and even Shinoa, who is a Hīragi herself.

History
Several centuries ago, the Hiragi family developed impressive spell-casting abilities and was successful enough to branch families, which have continued to serve them over the centuries. The branch families themselves have lesser families serving them.

Ichinose
500 years prior to the series, the Ichinose family served as the top family under the Hiragi. However, both the first and second sons of the Hiragi family fell in love with the daughter of the Ichinose family. The second son won her love. In retaliation, the first son castrated the second son and raped the Ichinose daughter, impregnating her with his child. Although he could have annihilated the Ichinose at any time, he chose to let them live on and suffer humiliation. This maltreatment continues into the Catastrophe light novels and even the Vampire Reign manga.
