Given that this is RWBY, our ships need more creative names than two character names roughly glued together. Fair warning I am NOT good at these.

Mokuren x Shiro: Hyperactive, Crazy For You

Mokuren x Geni: Fast Food, Lion Queen, Rip 'n Tear(?)

Mokuren x Tail: Touch Fluffy Tail

Priscilla x Robert: Pink Dreams, Sakura Arrow

Priscilla x Greyson: Castle (because they both have defensive semblances)
