The Black Abysses (ブラックアビス Burakku abisu) are an item appears in the Mewkledreamy anime.


Black Abysses are stones that can be put into people that have Black Schema (ブラックスキーマ Burakku sukīma), a black smoke-like matter that represents one's negative emotion, and cause chaos. The Queen of Nightmare's goal is to spread them as mentioned in Episode 14. Yuni uses the Crescent Moon Yuni Stick to put them into people.

Even though Yume Hinata is tasked to eliminate Black Abysses, she is not immune to getting one as shown that Yuni waited for an opportunity to plant a Black Abyss in her when she gets a Black Schema, as shown in Episode 16.

Yuni can even insert Black Abysses into those who do not even produce Black Schema as long as they are in a dream, like Maira Tsukishima in Episode 4.

Suu's glasses has the ability to see and pinpoint the location of the Black Abysses, as shown in Episode 7.

In Episode 44 it showed Black Abyss bigger than normal.
