Lin Yuan traveled through the world of Zongman, awakened the system, plundered the entries, and became a hybrid of a hero and a demon.

Many years later, he awakened the demon bloodline, was driven out of the hero village, and wandered to the town of Kouou, where there are many talented people.

At the beginning, he killed Issei Hyoudou, plundered the gauntlet of the Red Dragon Emperor, took in a capable sister, and obtained the master-servant contract magic.

He opened the gate of the world and shuttled through the worlds.

Renalei: "Everything of the master is everything of mine~"

Naruse Mio: "Perverted brother, kill you a hundred times!"

Yotsuya Miko: "Can you really resist the cursed spirits if you eat this?"

Eriri: "Why is my mother here too!"

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.
