Just had a great idea for a Saiki K. fic!
So basically, AU where Saiki is a ghost that kinda “haunts” PK Academy. He’s not that old of a ghost, maybe like…10 years. Toritsuka can see him ofc and he was still a psychic when he was alive, so other people could see him too sometimes.
He mostly just plays stupid pranks on everyone in the school; students, teachers, staff, no one is safe.
Regular Pranks: moving furniture a few inches in one direction; playing an annoying song over the speakers; writing funny pictures on the chalkboard etc., etc.
Pranks to “A-Holes That Deserve It”™️: pantsing someone in the middle of the hall; pulling their chair out right when they’re abt to sit down; having the water fountain spray water on their shirt; etc., etc.
He can’t use any of his powers from when he was alive, but he’s a powerful enough ghost to be occasionally seen by regular people and physically pick up objects.
(Him being Toritsuka’s guardian spirit is optional)
Saiki has no idea why he’s so drawn to these random students, especially when they gain so much attention! He understands that purple-haired perv cuz he’s a medium, but that kid with the 8th grader syndrome? The giant idiot?? That blue-haired, popular girl??? He does like that one normal guy. He’s absolutely perfect!!
He pretty much sticks around Toritsuka (just to make sure he’s not being a creep and totally not because he like being able to talk to someone who doesn’t run away, scared. Definitely not that.) and haunts the class that used to be his class. Saiki’s also mute, so whenever he talks to Toritsuka, he either signs or writes messages down on piece of notebook paper.
(Toritsuka didn’t know sign language at first, but he decided to learn it cuz he was worried Saiki was wasting too much of his energy just to talk to him.)
One time when Toritsuka is chilling with the gang, Saiki starts to become visible to the others. Everyone is freaking out, while Toritsuka is like “yeah, that’s just Saiki.”
Kaido: Th-Th- THERE’S A GHOST BEHIND YOU!!!
Toritsuka: Hm? *looks over his shoulder* Oh, yeah. That’s Saiki. He haunts the school.
Saiki: *waves at the group*
