The Mysterious Figure

I checked on the description of the whip and then stored it in my inventory, even though it had no use for me at the moment. I figured I could lend it to someone skilled in pyromancy.

Turning my attention back to the door that appeared after defeating Balor, I approached it slowly. The door opened on its own and I stepped inside, only to be met with a bright white light.

And I was suddenly transported to a grandeur and eerie throne hall.

Despite the ornate surroundings, my attention was quickly drawn to a powerful demonic energy that seemed to emanate from my left.

Struggling to maintain my footing, I turned toward the source of the energy, and... what I saw made my eyes widen in shock.

Ding!—

[You Have Come Across A Sealed Demon Lord...!]

I didn't have to see the system notification to tell what it was.

A huge, translucent crystal was suspended in mid-air, surrounded by massive, transparent chains and shining runes.
