Summary
When you die in real life, where do you go? What do you become?
Our protagonist lived a first life that was so meaningless it brought up a new question to whoever is in charge: did they deserve to go anywhere at all after they died? Or did they just need to try again?
Someone who is not a super-genius, nor has any drive to succeed, gets isekai’d into Donatello from TMNT 2003.

Summary
It’s something only somebody who has known him for a long time will notice it. His parents, his sister, his only friend since high school: they all have picked up that there is something different about him than other people.
Honestly, it even took him a while to realize there was something different about himself.
It seems like Hoseok can’t love, and, sometimes, it's all he can think about.

Summary
Chuuya tells him one night after a drink too many that he feels like he’s stuck on an endlessly looping rollercoaster. That the ride up doesn’t feel so daunting until it drops and sends him plummeting back down.
For a long time, Dazai assumes the highs must be better. Not good, necessarily, but better—anything has to be better than the aching stasis he lives in, an endless gray of nothingness that presses against his ribs and makes it hard to breathe. Chuuya’s mania sounds like freedom; to feel energized and alive, to wake up with a purpose—however unhinged—seemed like a fair trade for a little chaos and the inevitable crash. He used to watch Chuuya in those bright, impossible weeks and feel a kind of envy he couldn’t name. Chuuya would laugh too loud, talk too fast, waste so much energy on the mundane—and Dazai would think, God, I’d kill to feel like that.
He doesn’t anymore.
or ; how dazai learns that the highs aren't any easier

Summary
Peter Parker loses everything to save the universe—and then loses the universe anyway.
After being launched into Gotham by a multiversal maniac with a deeply personal vendetta, Peter wakes up as a kid again in a city he doesn't recognize. There's someone called Batman here. There are way too many Robins. Something called a Justice League exists, and Peter is pretty sure this is what copyright infringement feels like.
Gotham already lost its Spider-Man once, it's not letting this one go so easily.
(Somehow, Peter finally finds a home.)

Fourth-year cleanup hitter Sawa Eijun has spent years chasing every fastball, every stolen base, and every fleeting chance to prove himself. Now, in his final game for Ryukoku University, everything comes down to one swing.
Between the roar of the crowd and the echo of memories long gone, his mother’s laughter, his younger brother’s grin. Eijun must face not only the pitcher before him but the weight of a life defined by sweat, sacrifice, and stubborn determination.
One swing could seal victory. One swing could seal his legacy. But fate might have more in store than he ever imagined.

Summary
After leading Seidou to back-to-back Koshien championships as their undisputed Ace, Sawamura Eijun had finally conquered it all. He had survived the Yips, outlasted his rival Furuya, and proved that a loud-mouthed kid from the countryside could rule the mound. He was content, decorated, and ready for the future.
Then, he woke up.
Instead of his hard-earned gold medal and professional-grade muscles, Sawamura wakes up in his scrawny, 14-year-old body back in Nagano. He is a second-year at Akagi Junior High—a time when his pitches were unrefined and his "Numbers" didn't even exist. In a single night, the universe robbed him of his glory, his teammates, and his hard-won progress.
Furious and cursing the "Bastard Gods of Baseball" at the top of his lungs, Sawamura realizes he has two choices: mourn the future he lost, or use his "National Champion" brain to absolutely demolish the past. Armed with veteran instincts and surgical precision, the "New" Sawamura is about to turn the middle school baseball world upside down—and this time, he isn't letting anyone else take his mound.

Summary
Peter was meant to be forgotten, he didn’t think that meant being dropped in Gotham. Or in his eight-year-old body, in the least. Or with vigilantes trying to adopt him!
IN WHICH, Dr. Strange gave Peter one last chance at a life, instead of being emo around the faces who no longer recognized him.
