How I Saved the World Through Cosplay

Shirakawa Chisato is an ordinary girl who likes cosplay.

After learning that she has terminal cancer, she jumps off a building.

After that, she gets bound to a fanfiction System.

By cosplaying as characters, she saves amnesiac fictional characters who have been transported into old-school novels.

World One: The Miracle from the Longitudinal Timeline Arrives in the Treasure of Dusk and Night

He is the only miracle in a parallel world. The brown-haired boy gives a warm smile and pulls the bandage-covered boy into his arms. "Dazai, let's go see the fireworks with everyone."

World Two: The Youngest Executive Arrives as the Detective's Beloved Police Officer

This world is so incredibly boring. Osamu Dazai looks up at the policeman in front of him, who's aiming a gun at him. He wipes the blood at the corner of his mouth with a fingertip, his gaze dark and unreadable. But Oda Sakunosuke said he wanted him to join the side that saves people.

World Three: The Not-a-Monkey Cult Leader Arrives as the Replacement Canary of the Jujutsu World

At the moment of death, everyone is alone. The black-haired boy swallows the core formed from cursed energy, standing on the corpse of a "monkey." He smiles and waves at the strongest, who has just arrived. "Hi, Gojo."

World Four: The World's Greatest Detective Arrives as the Tennis Star of Tokyo's Prince

"If it suits me, then all is well." Are you people stupid? The culprit is him or her. I really don't understand adults. Hey, you over there, come help this great detective find the way.

After saving everyone, Chisato holds the secrets from their pasts in her hands and plans to quietly disappear without taking credit. But she doesn't know that they're watching her with dark expressions.
