Bungou Stray Dogs ABO: Double Black, the Plan to Lock Alpha Kurozai Up with Omega Chuuya

Osamu Dazai x Chuuya Nakahara. Double Black content, with Dazai paired with everyone.

Includes Her Highness Luo Tianyi, Hatsune Miku, magical girl Homura Akemi, and others.

The outline is below.

A wave of so-called transmigrators, afflicted with a strange condition, breaks out in Yokohama. They all have special abilities, magic, cultivation, and Systems; some are even gods. One god wants to destroy the world, while others want to conquer the universe.

Chuuya Nakahara has been married to Osamu Dazai for less than a month, and already transmigrators have appeared who want to steal his man. Ah, he's going to get every last one of them.

Osamu Dazai is a scheming, wicked Alpha top x short-tempered, tsundere Chuuya Nakahara, an Omega.

Theme: Double Black. They're often tangled up in a push and pull between each other.
