[Crossover] The Literary Greats You Ordered Are Here

Red Hood, a short-tempered guy with a love of literature deep down,

one day finds two kids on patrol, one named Baixue and the other Youxing.

From the information he gets out of them, they come from a world with people who possess supernatural abilities. There are no literary figures there, only ability users bearing the names of famous writers, whose abilities share the titles of their works. Most of the prominent ability users belong to different organizations:

Port Mafia

Armed Detective Agency

Special Division for Unusual Powers

The Rats in the House of the Dead

The Guild

"How do you know so much?"

"Uh, because we're holders of the 'Book' from a parallel world?"

Oh, I forgot to mention: the "Book" is the cornerstone of their world. Write anything on its blank pages, and it will come true.

Red Hood sighed. He'd picked up two enormous headaches.

Baixue seemed about to say something, but Youxing tugged at his sleeve.

"Youxing, even if we don't tell him, it's still going to happen!"

"Well, for some reason, a fourth person found out about the 'Book' in our world..."

The "Book" can be known by at most two people. When three people know, the world becomes unstable. When four know, the world collapses. So...

In his first month, Jason Todd, the young man codenamed Red Hood, received Kunikida Doppo, Nakajima Atsushi, and Akutagawa Ryunosuke, plus Akutagawa Gin and Higuchi Ichiyo.

In his second month, he received Edogawa Ranpo, Sakaguchi Ango, and Oda Sakunosuke, along with five children, four boys and one girl.

In his third month... he received a calico tomcat.

Jason was going out of his mind. He'd picked up two world-ending headaches!
