Sheik - The Shinobi Vigilante

Izuku Midoriya in his second and final year of highschool finds the remnants of an ancient clan of warriors called the Sheikah. With no other options in regards to fighting crime he turns to 'vigilantism'.

(Also, Izuku won't be calling Bakugou 'Kacchan'. I'm sorry but his mindset is a little to childish for my taste and calling someone by an endearing name after they bully you for years shows something like a different version of Stockholm Syndrome)
