I am looking for a Manhwa a read in the past but forgot the name:

It’s a guy Mc he gets kicked out of his family for having a f rank ability but gets picked up by the fist king and trained for years then sent to an academy.

Mc has brown hair tied up in a ponytail with a purple ribbon

Mc has this black dragon robe

His sister is on the student council

Their is this pink haired girl that’s a necromancer

That’s all I can remember
