The second protagonist of the story. Logy is a serious and "down-to-earth" person, but is also kind. He has a burn scar on one of his arms, and he seems to avoid talking about his past. Like Escha, he is a government official, and is assigned to work with her. Instead of a cauldron, Logy uses specialized tools to assemble new weapons and armor and to disassemble items in order to discover their properties.
