Leg Eater is blind but has a powerful sense of smell. He is a reserved bug who reacts with anger at any threat he may perceive. He is fixated on earning Geo, believing that if he has enough of it, it will make him become a king. Despite his own greed, he is prone to accusing others of the same sin, even wrongfully.
After being paid, Leg Eater opens his Charm shop and sells Fragile Charms that break upon death. He provides a repair service for broken Charms in exchange for a fee. If the Knight wears the Defender's Crest Charm, he appreciates the smell and sells and repairs his Charms at a 20% discount.
Leg Eater notices if the Knight wears one or two Unbreakable Charms bought from Divine of the Grimm Troupe. Enamoured by her pheromones, he seeks her after the Knight presents to him the full set of Unbreakable Charms.
After this, he disappears from his camp and his claws can be found resting in Divine's room. Divine comments that she liked this final "gift" from the Knight, suggesting Leg Eater's gruesome fate.
↑Leg Eater: "Don't try to steal my secrets! I'll steal them right back. If you're cruel to me... you'll be sorry."
↑Leg Eater Dream Nail dialogue: "I'll make more... and they'll give me more Geo. If someone comes by, they have to give me their Geo. If you have enough Geo, you become a king. When I get enough Geo, I'll become a king..."
↑Leg Eater: "You're a greedy, nasty little wretch. You need to share your Geo..."
↑Leg Eater: "You're sweet... to share such a tasty smell with me. Do you want a gift in return? Cheaper... Yes. My beautiful gifts... I'll give them to you. Cheaper."
↑ Leg Eater: "My charm! What did you do to it?! The smell... different. Strange, but nice. Very nice!"
↑ Leg Eater: "Those charms... that smell! So so much! I want to... Yesss! I know where you are now. Above me. Much above me, but I know where to go. I will come! Don't try to hide from me!"
↑Divine: "One final gift! Ahhhhhhhh! I liked it very much. Very, very good. So good!"
