Yumenberg

Yumenberg is the femslash ship between Celestia Ludenberg and Yumeko Jibami from the Danganronpa and Kakegurui fandom.

Canon
Since Celestia and Yumeko are from different series, they never met in canon.

Both characters gamble, have no problem with lying and have questionable mental stability. They also have dark hair and red eyes.

Fanon
Some fans theorize that Yumeko could have received a different life schedule. This schedule could have said that she would attend Hope’s Peak as Celestia Ludenberg. And knowing that Yumeko would accept her fate she ended up doing so. However, it's not confirmed yet.

Yumenberg sailed as a result of both characters being fairly similar. While the two having the same colored hair and eyes makes them look like sisters.
