Elendira the Crimsonnail
1st Manga Appearance:

Elendira the Crimsonnail is the mysterious 13th Gung Ho Gun. The most surprising thing about Elendira is that she isn't a she at all, but a transvestite. Aside from that Elendira carries around a large case that shoots very large nails. He's also envious of Legato, because Legato is obviously more in Knives favor than Elendira is. Elendira also controls an air ship that belongs to Knives.
