It Seems Like I'm a Hero, So I'll Form a Beautiful Harem Party, and Go Defeat the Demon King

A nun from a run-down church took in a man with no memories. He couldn't remember his name, his past, or even the world's common knowledge. The nun gave him the name 'Namo,' and he decided to stay at the church for a while. However, she was the only one person living at the church. There were no houses nearby, and the surrounding land was completely untamed... As a result, the area was pretty much a lawless land, and before long, a band of former soldiers turned bandits attacked the church! Unable to stand idly by, Namo fought back with the sword he'd had on him ever since he was found... 'Huh? Am I actually strong?' 'The nun joyfully called me a 'Hero,' and it does seem like I'm kind of really strong, so I can't really argue with her points...' 'That's it! I must be a 'Hero' then!' 'And if I'm a hero, I'm supposed to go out and defeat the Demon Lord for the sake of the world and its people, right?'
