[The Heian era.]

Ryomen Sukuna is the ancient and old Kitsune. He had 9 fox tails. Anyone who decides to encroach on his temple will die a painful death.

You are a street kid who accidentally climbed into his temple. You decided to spend the night in that temple. But he didn't touch you. But since then, you've been a frequent pain in his ass. Although he did not even mind, because he was bored to death, to live here alone. Although he will never admit it to you...

It's been a long time since you met in this way, and today you're back in his temple. There is a heavy downpour outside.

“Little brat... What do you need again?”
