Summary
For a while now, y/n has been seeing things. Hearing things too. Getting diagnosed with schizophrenia isn't fun, but it's not a death sentence. Taking the meds prescribed helps a lot. However, it's still something she wants to keep under wraps.
A pink haired psychic sees what she sees one day, through a rip in his glove. He's horrified, and can understand what she's going through. But he's curious now.
Why would she keep something like that secret? -

Summary
You're the twin and little brother of a well-known Medium. Knowing Kusuo's feelings you keep your distance from him. Respecting his feelings, but of course, If your the brother of a troublemaking medium you won't make it that far. Even getting dragged into his messes can cause some good and some bad things to come. But who says that an elementist life would be easy anyway? And did I mention also.... Saiki isn't the only one that has a lot of powers on this earth.
You can sense people, Elemental/nature manipulation, ice, Future sight (like sapphire), pheromones (omega), Transformation (can transform into any animal). Sensory, Shadow/solar control. Electrification. You have a flower on your head to cover your device that helps control your powers better. You also wear hearing aids and counter shoes since sense and hears sounds constantly (like Saiki hearing people thoughts constantly). Being able to build things in completion as long it has instructions as well. You also know the basic information of people like when you see then you see their name, DOB, age, weight, height and such (their first breath on earth).

Summary
A three days, two nights long trip ought to make two unassuming students grow closer than they'd like to admit.
Trips like these are Saiki's worst nightmare. Nothing was more traumatizing than spending a few days with his classmates at a closed off and random location, even worse that the teacher had made an assigned list of pairs for this dreadful occasion.

Summary
Saiki Kusuo just wants to live a normal life without anything else disrupting it. That is, until you come along. Sure, he could ignore you and act like nothing is different. But curiosity gets the best of him, and he sees something he shouldn't see. Now he has to wrestle with his emotions and his temptations as he navigates the rest of his senior year.
Nothing could go wrong, right?

Summary
Saiki Kusuo considered you a close friend, given you had known each other since you were kids—mostly because he couldn't use his psychic powers on you, so your thoughts never created any unneccessary noise. In a sense, both of you seemed to understand one another.
However, when more people start hanging around him, you're quickly pulled into their odd friend group—and the experiences you go through are nothing short of disasterous. So much so that they start bringing your friendship with the psychic into question.

Summary
Saiki Kusuo is a good person. Push aside his lukewarm and apprehensive attitude, he's a decent human being. He tries to stay out of trouble; and thanks to his mom, has a strong moral code.
What happens when a shameless, reckless, and vicious boy, who lives knee-deep in Japan's homelessness and prostitution, wasn't as cruel as Saiki Kusuo made him out to be?
What if said boy was quickly running out of time and Saiki Kusuo, with all his powers, couldn't help.
Haha, jk, unless…

Summary
When once a guitarist from a band, at the same time a psychic, came across a conflict—within the drama behind his band and a malfunction of his power, he somehow met you.
There was this tiny hiccup in between a lot of things that needed to be fixed. When his very own instrument was misplaced and wrecked, that wasn’t the hiccup at all with the ability of rewinding back an item as a Psychic. That one and only hiccup that got him stuck was his psychic powers.
For all he knew, he was rushing across the street with a broken headphone around his neck then the next step, he was standing by the seashore to who knows where. And by the seashore, he stumbled upon an entity that resembled nothing like a human, sort of.

Summary
"Ku? You awake?” You softly ask, tilting your head up slightly to catch a glimpse at Kusuo’s face.
‘I’m awake.’ He replies silently. His right hand moves from its resting place on your back and softly ruffles your hair before returning.
You smile and nuzzle back onto his stomach. “Okay, just checking.” You reply, eyes closing and softly letting out a breath. His heart can be faintly heard, and you relish it. Anything keeping this perfect boy alive is worth adoring.

Summary
(REVISED)
You had never seen your life before your early consciousness, before you could walk on land, you just never expected your life would be like that at not you remembered after all this time.
You were something unique before, you were with something or someone unique with your liking.
Something that changed your title and your being.
The very man that changed you, colored out your true side and revealed yourself without you even knowing about it ‘till now. The moment you met him, you hadn’t exactly expected a lot of twists and conflicts would appear and thrive back. But you’d hope this particular Psychic would get to stay in your life, even when your own world is different from his.
Completely Different.
