Tensei Yuusha no Kimama Tabi

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! With these memories recovered and powers reawakened, Leon decides to start a new carefree journey!
