Summary
Just when Saiki Kusuo thought he had finally secured a quiet, asteroid-free life, a cosmic glitch rips through reality itself—thanks to a poorly timed miracle and an unstable psychic reset. The result? Universes begin to collide, and Saiki finds himself unwillingly playing interdimensional host to a cast of absurdly powerful and even more absurdly dysfunctional guests.
From explosive mages like Megumin to dramatic shadow-obsessed vigilantes like Shadow, overpowered loners like Jin-Woo, and unpredictable oddballs like Gojo Satoru, Saiki's apartment—and mental stability—is pushed to the limit.
His goal is simple: fix the glitch, send these walking headaches back to their own worlds, and finally return to peace and coffee jelly.
But just when Saiki thinks he’s turning everything back to normal and getting rid of the uninvited guests, a more eerie, mysterious, and unexplained phenomenon begins to surface—one that no amount of psychic power can fully predict. Something darker is watching from the cracks between worlds… and it might not be as easy to banish.
Because sometimes, the real disaster isn’t the guests—it’s what followed them in.

Summary
Saiki was an idiot. The instances where he would admit his stupidity are rare, barely countable with the fingers of one hand even - but this time, he could not deny the scope of his foolishness and guilt. And he could have avoided this situation in thousands of ways because he knew, he always did. But
Saiki let their relationship grow that deep because somewhere within him, he strongly believed a ‘them’ could have existed. Aren and him could have been happy in another universe, together. Now they were both sad apart.OR Saiki fell in love with Aren, but refuses to love him, because how can someone like him seek for such a human pleasure ?

NONE OF THESE CHARACTERS BELONG TO ME! They are from the show/manga series "The Disastrous Life of Saiki K" (Saiki Kusuo no Ψnan), and belong entirely to Shūichi Asō. The storyline is my idea though, based a little off a few songs - playlist will be shared. Please don't steal my work!

Summary
There's one word Saiki Kusuo would use to describe the life he's led since college: boring. But, he would always say it was a good kind of boring, like he always wanted. But not anymore though. This boredom was easy to ignore at first, but as the years have dragged on at a snail's pace but also simultaneously distressingly quickly, one day Kusuo realises he doesn't enjoy his life anymore.
In the years since high school, our psychic has attained his dream of an ordinary life, but is it still what he wants? It's kind of boring, isn't it? After a series of frustrating events and a costly mistake, he takes the time to reflect upon this, and has an unexpected realisation.
Meanwhile, elsewhere in Japan, a woman who by all accounts was expected to have an easy life, has had anything but. She's about to hit her breaking point…
