Mungo

In a distant future where nature has reclaimed its rights, and humans combine advanced technology, medieval techniques, and magic to survive, Mango, a cool guy, is considered the protector of a peaceful village.
In the past, he was one of the few adventurers daring enough to explore the vast plains in search of resources. Now, the villagers rely heavily on him, but he isn't their leader.
He wielded a mighty sword equipped with a system that could infuse various poisons, and he also had a yoyo with integrated blades, allowing him to grapple onto creatures with ease.
