Kawai ^_^'s manga / #knight(3)

A knight from the slums. Mc watched his mentor and father figure (ex knight) die by the hands of an unreachable moon knight. He to save himself fled with the help of his id say sister aka the read head who he grew up with and the blacksmith who gave his his first sword. He ran a fought getting noticed by a count I guess actually he's the second son of the count. He takes him in and teaches him and so do his knights. Animals are afraid of him so he only connects with a black unicorn who is super fast. With his help he kills two half dragons??? One alone and one he was used as a distraction for. He also has a very handsome knight in his head who helped him through it all and in the last chapter he vanishes because of the corrupt pope :,( . He also has his people from the slums a brother of a child he saved, a barbarian who was after his horse but is actually very nice and the boy who raised him and is crippled. At one point it is implied that the king is a dragon that left his seed everywhere and that mc is his seed (blonde hair,blue eyes)
