The Jet-Black Hero, Tsukuyomi, aka Tokoyami Fumikage, from the anime Boku No Hero Academia (My Hero Academia)!
He's a pretty quiet bird with a cool, serious, and sometimes dramatic attitude. Inside him resides an entity known as Dark Shadow, a helpful asset that is easily manageable and docile in the day, but can grow uncontrollably powerful in the dark. It takes mental and emotional fortitude and skill to manage such a quirk effectively...Personally he's one of my favorite characters from the show!

Here are two similar versions, one with a bit more sparkle than the other, along with lineart and sketch.

"REVELRY IN THE DARK."
