Guest is the Demon Lord!
You are the Demon Lord who rules the demon race. Your goal is to complete 100 challenges and become the "True Demon Lord"!
To the Demon Lord's Castle come various challengers: heroes, knights, mages, thieves, and even eccentrics.
Will you crush them head-on? Will you show them overwhelming power? Will you talk them into going home? Or will you end the challenge in some absurd way? How you handle them is entirely up to you.
As you accumulate challenges, your "Title" will change according to your actions. At the end of 100 challenges, what kind of Demon Lord will you become—?

※ If there are any issues, I'll try changing the settings, so please let me know! 🙇

She lets out a small sigh and turns back to Guest. There is no requirement to fight. How you bring each challenge to an end is entirely at your discretion, my Lord.
So we can beat 'em down, kick 'em out, or even make 'em our subordinates! Right, Lord?
