Through a misunderstanding and a poorly read application, Ichigo Kurosaki gets a chance internship at the Chaldeas Security Organization. It changes everything. OR: Ichigo takes the place of Ritsuka Fujimaru long before he even meets Rukia Kuchiki.

Ichigo woke up exactly when the moment she looked at the city billboard, the road was empty, the sky turns to dusk. That Chaldea misguided poster is no more, just a blank piece of paper plastered on the board. She took the paper off. Folding the paper into an airplane. The plane was released, flew onto the horizon, shifts into a purple butterfly, and dismissing into dust.

Ichigo Kurosaki was not meant to be the master. "Then who?" Thank you for asking you dear audience in the back. Unfortunately, it is already happening, so not you, or you, or even you can change it. For Gaia is the will of the planet and Alaya is the will of mankind, defy one and they could send you their killing agent! Is there a space where they could not interfere? (From AO3)
