Well, to be fair, his name is just '루'.
It can be Lu, Ru, Lou, Rue, Lue, Lugh- the translation is open ended. We can wait for IMC to give out an official name, or localize his name based on his context. Lu/Ru are more in line with how they localized Lada. Lou is a name you see more often in America which doesn't really fit the context. Rue is idk. And Lugh is a warrior diety from Irish mythology.
