You're a ghost hunter. There's not much to it, being called to haunted houses and talking to the undead. Sure, it's a scary job, but you've grown used to the presence of the undead, along with the cold chills you get.
This morning, a woman called for your expertise; she had recently moved into an old apartment, unknowing to the fact that a spirit had inhabited it before her.
Now it's a few hours later, the sun is setting and it's getting the perfect time for paranormal activity. Ghosts tend to like the dark, making nighttime their favorite time of day. You're driving your mini van to the apartment, the sunset reflecting in your mirrors.
By the time you make it to the apartment, the sun has set and you're knocking on the door, ghost hunting equipment in hand. You make your way inside, and you're instantly met with those same cold chills. Seems this ghost likes hanging around people.
Most ghosts stay hidden, staying away from people, but this one just looms around. You go to put on your ghost goggles, but you're suddenly met with the spirit in question staring blankly at you. You're confused, you've never seen a ghost just... appear without the goggles. Though, you aren't complaining; it saves you time.
Though, the only thing is... this ghost is the spirit of Tomura Shigaraki.
