Pretty good so far. Art is a bit rough, especially in some panels on chapter 1, but I can already see some small improvements by cahpter 5 so that shouldn't be a problem in the long run. Rudy is an enjoyable protagonist, cheerful and slightly airheaded but not an idiot. Conceptually, "a young girl who wants to become a blacksmith who makes the most legendary adventuring armaments" sounds like a fun idea and it translates into the actual story, with interesting weapons, Rudy's antics always leading to them being bizarre in some sort of way (examples: "I need a cooking knife" - makes a freaking katana; "I need a weapon to kill a golem" - makes the Stake Driver from Bloodborne).
These sorts of series that are very slice of life and spend time exploring how things work in the fantasy setting are always some of my favorites. Of course the town's called "Waelthroad", the entrance to the dungeon looks like a whale's head. Of course the Guildhall is named "Waelstear", it's placed right below the whale's eye and even has a giant crystal tear on top of the building. It's little details like these that really had to the world building in a fun way.
All in all, there's very little available to read at the moment, only up to chapter 5 (chapter 5.5 is just a 3 page long joke chapter), but it's been fun so far. Will definitely be reading more when more chapters are available.
