Nice to Meet You, Onii-chan

Upon discovering that the water is his room doesn't seem to be working, Roan decides to go ut and buy breakfast. While on his way back to the inn where they are staying, he over hears some men talking about a Golden Thief Bug in the sewers, which must explain why his water isn't working. Roan heads back to the inn and convinces Yuufa that they are ready to head into the sewers to confront and kill this Golden Theif Bug. After encountering and defeating some minor monsters, they see a small pink poring, which they follow and discover a girl in danger. They rescue her and she introduces herself as Ma-Chan. She is a collector of valuable items. Ma-Chan follows Roan and Yuufa (much to Roan's dismay) amd because of her annoying chatter, Roan yells at her to shut up. She runs off and a few minutes later comes running back, followed by The Golden Thief Bug.
