nacht

A sexy ass frog.

Nacht mare is the literal translation of 'nightmare'.

It's a dream so horrible and surreal it could only be made worse if it had been in German.
It was explained in the movie 'Rachel Getting Married' by Anne Hathaway's charater Kym.

Nacht Faust is the elder son of the noble family of the house of Faust on black clover

He has a twin brother called "Morgen"
His name means night and his brother day

Consider it important bc nacht's magic attribute is shadow magic and morgen's light

Nacht is viewed as bad mannered and only thinks for himself, he befriends yami sukehiro a guy with a similar magic attribute and later on his brother also
On the age of 19 nacht became a devil hoster to 4 devils and one time his parents showed him a bracelet where he could summon a high ranking devil, lucifugus, he accepted but he wasn't able to make a deal with him as lucifugus was killing everyone, Morgen stepped in and saved nacht but this coated his life after that nacht never forgave himself and he made his appearance similar to his brother he thinks that whenever someone loses somewhere/something it's his own fault (caused by the trauma of his brothers death) he believes you always have to be honest despite what you say is the painful truth and in the databook is mentioned that he likes rightful people

I don't think I want to say something more about him he's perfect on every way
