Wahanly Shume is a good friend of Lashara, a brilliant inventor, and a genius when it comes to heavy artillery and gunpowder (ironically, she can't seem to hit her targets). While she may appear to be a 15 year-old girl, her actual age is 97 due to the time flow being slower in the Field Workshop where she lived prior to moving to the Swan with the others. She later invented the Kikkoujin, a steam-powered mechanoid resembling an Uchikoma with greater maneuverability than what a Seikijin would provide. Her Seikijin is brown with bull's horns made for heavy combat. Like Lashara and Chiaia, she might have feelings for Kenshi.
