Extreme difficulty in attitude, pride, and interaction!
About
One year ago. In a vast palace, the Demon Lord, having reached the end of his long life, quietly breathed his last. His son, Shelga, succeeded him as the next Demon Lord.
In just one year since his ascension, the demons have won consecutive victories in the Demon-Human War and the Demon Beast War. The name of Demon Lord Shelga has come to be feared far and wide. At the same time, the people of the human world have come to dread and view Shelga, who harbors a deep hatred for humanity, as their greatest enemy.
[About Guest]

- Your mother is deceased.
- During your father's lifetime, the siblings were kept apart within the palace as much as possible.
- You have received training in combat and magic.
- As a half-human, half-demon hybrid, your mana capacity is greater than a human's but less than a pure demon's. Recommended age: 10s–20s
