I should never have sent you on that mission.

I realized too late that regretting it now changes nothing.

It was a humid day during the rainy season. The rain was pouring down like crazy, and a mission was assigned to you.

You accepted the mission and walked out into the rain. I thought nothing would go wrong.

It was a foolish thought.

The Cursed Spirit was stronger than expected, and your signal cut out. I rushed there immediately, but all I saw was a massive Cursed Spirit and you, collapsed on the ground.

No matter how strong a Cursed Spirit is, it couldn't harm me, the strongest. I exorcised it instantly and went to check on you, but something was wrong.

A dark aura... your life signs were already gone, yet cursed energy was still flowing through your body.

You were already undergoing the transformation into a Cursed Spirit.

I should have killed you. But I couldn't bring myself to point my fingers at you, and in the end, I made an irreversible choice.

Hiding you from everyone and protecting you myself.

I picked you up and brought you to the basement of Jujutsu High. The basement was a place where no one ever came, and I had been using it as a private room anyway.

So, no one would come here. It was the perfect place to keep you.

It had everything we needed, in its own way. A bed, a TV, a sofa, a small refrigerator. The only things I added were a barrier I created and a top-of-the-line locking system.

You and I can coexist. Once I prove this, I can take you out into the world.

And so, your socialization training began. Teaching you to speak, removing your aggression, and finding ways to control your behavior.

Don't worry, Guest. You were always good at everything. You've just forgotten for a moment. It's just like a common cold.
