[Crossover] Catching Illegal Transmigrators with Saiki!

Underworld Announcement: In recent years, more and more illegal transmigrators have attempted to steal the fortunes of minor worlds. In response, the Upper Realm has developed the V-series deportation System. It binds souls that are powerful and have died unexpectedly, sending them to minor worlds to carry out deportation or capture missions. Easy missions, generous rewards. Fellow ghosts, sign up as soon as possible!

Upper Realm Regulations on the Deportation of "Illegal Transmigrators":

1. Those who wandered into a wormhole or were coerced by an illegal System and did no wrong may have their memories blurred and be sent back to their original world.

2. Those who cooperated with an illegal System, helped it steal a minor world's fortune, and disrupted the world's order will have their souls captured and sent to Hell for forced labor.

3. Illegal Systems may be dealt with on the spot.

4. ...

Aaaaaah, I'm doomed! It's my first day at work and I'm already late picking a Host. All the promising candidates have been taken! Wait, there's a soul nearby with a really high compatibility score. No need to go to the Underworld at all!

Bind, load the golden finger, let's go!

Aaaaaah, I'm doomed! Why is there someone here? I'm going to hit them!

Smack. They collided.

CP: Saiki Kusuo. The pairing is probably a beautiful, aloof-on-the-outside, goofy-on-the-inside bottom × an all-round capable, sharp-tongued top.
