Ashes of his throne

Just a fun challenge to see if I could make a manga and turned out kinda shit but it is what it is anyways I’ve posted this on a few websites and that’s pretty much all. Synopsis: Some dude with memory loss, village done burned to the ground and can’t stop seeing this silver haired girl. He embarks on a journey to defeat the demon king but has to face a bunch of obstacles blah blah blah and gets a harem.
