Gu Yi is an utterly ordinary angst-inducing writer. After writing too many fanfiction tragedies and tormenting too many readers, he is dragged along by their resentment and forced to transmigrate into a world where various anime and manga universes converge.
Fortunately, even after transmigrating, he is not completely without support.
He has gained a special superpower: replication.
His curse for writing too many tragic fanfics has instead become his support: by reciting lines from tragic characters, he can use their abilities or convert them into attacks or defenses of equivalent energy.
The more heartbreaking the line, the greater its power. The longer the line, the more powerful an ability he can wield.
What's more, reciting several different lines together lets their energy effects stack.
The only catch is that once he finishes reciting and the battle is over, a translucent screen appears above the battlefield and plays the scene the line came from.
Gu Yi (grinning wickedly): Now that you mention it, I'm wide awake.
And so, before each battle, one line after another rang out across the battlefield:
"Sakura o douka, aisuki (I love cherry blossoms more than anything)"
The Word Spirit: Judgment envelops the entire battlefield.
"I love you three thousand times"
An army of Iron Men descends.
"Natsubate ni suginai (It's nothing but the summer heat getting to me)"
Maximum Technique: Uzumaki, along with an army of cursed spirits, is unleashed.
"Moushiwake arimasen ga, Hagi, yakusoku o hatasenai kamoshiremasen. (I'm sorry, Hagi. I'm afraid I may not be able to keep my promise.)"
A gigantic protective shield descends.
"Watashi wa Yomi no michi ni nigeru shika nai kamoshiremasen. Sayonara, Zero (I may have no choice but to flee down the road to the underworld. Goodbye, Zero.)"
A hail of bullets, and a mask of deception.
"Ketsubetsu no toki kitareri, sore wa sekai o tebanasu mono (The time for farewell has come. With this, I relinquish the world.)"
Salvation that envelops the world.
"For The Greater Good"
Love is magic, and a cage as well.
"Koko wa yuiitsu kare ga ikite ite, shosetsu o kaite iru sekai desu ne. Konna sekai o kesu wake ni wa ikanai yo (This is the only world where he is alive and writing novels. I can't let a world like this disappear.)"
All abilities are nullified in an instant.
(The collection of tragic lines continues to grow.)
Everyone (depressed): Shut up! Just shut up! I can't stop the PTSD!
The world (seething with resentment): Even in another world, you can't stop yourself from making everyone cry, can you?
Gu Yi: Of course I have to say them out loud. How could I keep such tragic and beautiful stories to myself? (grinning wickedly)
Of course, he also has a little selfish motive.
If I tell everyone early enough, then everyone will know, and the tragedies won't happen, right?
PS: The lines come from Dragon Raja, Marvel, Jujutsu Kaisen, Detective Conan, FGO, Harry Potter, Bungo Stray Dogs, DC, and more. It's a big mixed pot of universes, so out-of-character moments are inevitable.
PPS: Even in another world, the protagonist still writes tragic fanfiction and draws heartbreaking illustrations. He's the reincarnation of a walking angst machine.
Theme: Everything for making people cry, everything is for making people cry, making people cry for everyone
