Misaoji

Solo adventurer and hero Leon was a master of all trades: sword-fighting, magic, healing, you name it. When he single-handedly defeated the Demon King, a curse was placed upon the lone hero. Without a party to save him, they both met their tragic ends. Years later, a timid noble boy is attacked by an ogre, triggering memories of his past life as the great hero who shares his name—Leon!
