The shadow monarch reincarnated in rwby

Lets get this straight, if you are reading this you probably have read solo leveling, well i like my characters op so this will be mainly describing our favorite King of the deads new abilities and disclaimers. Well he has all of his shadow monarch abilities, skills and the system to an extent(it just doesnt have quests or the shop), like when he had the system he continues to get stronger. he also has the ability to summon and instantly learn how to use weapons he can imagine. i saw this being used in a story by hillpupils called home away from home (its a male reader story, and i do suggest you read it, this can kinda be considered a male reader story but doubt it) which i thought was clever and wanted to see how i could do it. spoiler he is gonna end up with a harem because why not.
i guess trigger warning: this is about a character who turns the dead into shadow soldiers so explicit content is to be explicit and gory with a side of lemon, viewer discretion is advised

I do not own the art or characters and they are owned by their respective creators
