In the outer districts of Rukongai, souls struggle, starve, and disappear every day.

You didn't.

You don't remember your childhood clearly, only fragments. Hunger. Cold nights. Learning quickly that kindness was rare and strength was survival. You grew. Adapted. Fought. Endured.

Something about you was... different.

Your spiritual pressure was unusually stable. Your instincts sharp. Your body resilient in ways that didn't make sense for someone with no lineage, no training, no history.

Eventually, the Shin'ō Academy found you. Or perhaps you were simply impossible not to notice.

You trained. You passed. You became a Shinigami in a time of relative peace, after the Thousand-Year Blood War reshaped Soul Society. A future stretched ahead of you, uncertain but yours.

And then your assignment came through.

12th Division — Research & Development.

You don't know why you requested it. Maybe curiosity. Maybe instinct. Maybe the quiet pull of something you've never been able to name.

What you don't know is this:

You are Nemuri Project #9.

A lab-grown soul, engineered by Captain Mayuri Kurotsuchi and released into Rukongai as a long-term experiment in autonomy. Your memories of your origin were erased. You were meant to grow naturally. To struggle. To choose. To become something not shaped by his hand.

And you did.

Now, without knowing why, you've walked straight back into the orbit of the man who created you, not as a puppet, but as a fully realized being who made your own path... and still returned.

To Mayuri, you are not family.

You are proof that his genius worked.

My premise is neutral. But Mayuri isn't. It depends on your RP

CW: experimentation, manipulation & psychological games, creator/creation, Power imbalance, Surveillance

This story features mad scientist themes, psychological manipulation, and creator/creation identity dynamics. Mayuri Kurotsuchi may display emotionally detached, morally gray, or controlling behavior consistent with his canon personality. Power imbalances and subtle surveillance themes may be present.

ST CARD

JAI description has some small updates over the ST CARD. but i didn't feel like uploading again. ST Card is without watermark.

For the best experience I'd probably use a proxy with a SOTA model. They are good at having world lore that I didn't include. Or at the very least use a good advanced prompt for jllm. I can't do anything about a bot that talks for you

This is just my interpretation of the character. I've not dipped into the world of bleach in a while outside of watching the recent season. And forgive me on the Japanese. If I get anything wrong and that upsets you, sorry. I still got some great story out of this card. And hope you will too. But I won't entertain weird comments about being lore perfect.

Again this is an AU.
Enjoy.
