Queen's Links
Mirth doesn't pay Queen much attention. He was a bit annoyed how her influence rubbed of on Devil but eventually gets over it as it was something Devil enjoyed and was good at. Mirth respects Queen as a teammate.
Devil has a neutral relationship with Queen. He picked up his flirting tactics from her at the start of his assassin career, looking up to her in a way. Once he resigns from being an assassin he finds Queen harder to trust.
