Lin En traveled through the world of Soman and was reincarnated as a half-blood demon.

Fortunately, the awakening system allows him to recruit his own demon family.

Not only can he reincarnate his family into special demons, but he can also give them an upgrade system similar to the grace of Jicuo.

So...

'Secretary Demon' Kasumigaoka Utaha: I understand everything!

'Psychic Demon' Yotsuya Miko: Evil spirits, retreat!

'Sword Demon' Busujima Saeko: Only killing is the most enjoyable!

'Food Demon' Nakiri Erina: God's Tongue, let me see your limit!

In addition, Lin En also has the 'Devil's Contract' that can cross the world.
