Summary
"Just—hold still," Kurosaki breathes against my ear, and his other arm circles my waist, keeping me steady. "Sorry," he utters before his glowing eyes disappear from view, and I feel something sharp scrape the delicate skin of my neck.
Oh. I didn't see that coming.
A new transfer student has come to PK Academy, and while Saiki Kusuo tends to do his best to stay away from newcomers, his apparent friends are adamant in befriending this new guy. The only problem is that ever since Kurosaki Hiro stepped into his school, Saiki's powers hardly work as they should. Not only can he not read Kurosaki's mind, but he can't read anyone's mind the moment he's in the same vicinity as him.
To make matters worse, Kurosaki doesn't even seem to be human.
What a pain...

Summary
Kaidou meets a boy with powers just like his! Except, his bandages are a normal white instead of a flashy red like his.
Oh well, he'll forgive him for that, nobody can be as cool as The Jet Black Wings after all.
(And of course, this new first-year pair and his best friends Saiki and Aren are an important addition to his new group to fight against Dark Reunion with!
Nendou not included, he's strong but his intelligence undermines The Jet Black Wing's hero squad.)
Or;
The BSD Wan high-school bit where Dazai acts chunni made me start thinking about Kaidou gaining a friend willing to play along with his delusional ass. So naturally: high-school AU Dazai Osamu transferring into PK Academy.
And then I added high-school AU Fischl, because there was not nearly enough chunni in this fic.

Summary
Toritsuka Reita has always been severely depressed. However ever since the... Kusuke incident, he's been getting worse. Saiki has begun to take notice of this strange behavior when Toritsuka doesn't show up to school for nearly four weeks. Meanwhile, mysterious, violent earthquakes are shaking nearly all of the Greater Tokyo Area. And they all seem to last at least the same amount of time as Toritsuka has his panic attacks. As Saiki struggles balancing these new earthquakes and mysterious phenomena happening, he also has to juggle Toritsuka's sudden behavior change. Little does he know, the two events might be more close in relation than he thought.
A lot of this work is heavily inspired by many of the fics under the 'Toritsuka Reita needs a hug' tag. I'd love to thank all of these wonderful authors for inspiring me to write fanfiction! Please check them out!

Summary
Once it had passed, Saiki gave his son a once-over, checking for any injuries or discomfort. There was nothing. Kusei looked at him with bleary eyes, and now that he was securely in his father's arms, went promptly back to sleep.
Saiki deadpanned internally. He had almost pulverised the plane. Good grief. Better not think about that for now.
__________________________
Aka: Saiki's disastrous life continues even in his thirties, now with a (perfect) wife and a baby, who was starting to develop the same overpowered tendencies as his father.
