With many edits, but there is no doubt that Fette Fraktur was used as the basis for the letters.

Older Logo use this font (post in attach)
and this new logo is a custom of the older

font Name Please

sorry; i don't know actually
But for the lowercase, the base is Fette Fraktur

The First logo of Black Clover

Was made with Uppercases B et C
of the font Darkstone (Thanks to JerseyGirl for his help)
with a small cutomization

Good work imagi. Very informative presentation.
I should have been clearer in my original post that Fette Fraktur was the basis for the lower case and that the upper case was from something else.

Thank You donshottype;
In the New logo i very like the B but the C is not a good work for me

Thanks!

J'ai beaucoup aimé, je vous conseille de regarder Black Clover en VOSTFR !
