[Tokyo Revengers] This Beautiful Yet Cruel World

The heroine is a member of the Demon Slayer Corps and is no weakling in battle.

However, she dies in the line of duty during the timeline of the martial arts story. She will be brought back later.

Shinichiro and Akane are alive.

The Demon Slayer timeline has been heavily altered. Even if someone develops a Demon Slayer Mark, it only means they die young; they won't die in their twenties.

In the current timeline, Muzan has already been reduced to ashes. The Demon Slayer Corps mainly has to contend with the Twelve Kizuki.

The heroine is the eldest daughter of the Kamado family and Tanjiro's older sister.

She is a powerful fighter and has a pretty sound sense of right and wrong.

She'll do her best to set everyone's moral compasses straight, especially that rabid dog Sanzu.

Hjjj, you bastard, bring back all the characters who died!

Later on, the story may cross over with other anime.

Theme: Everyone, go on living happily.
