I think the emperors guardian is the girl in the top of him in the first panel

That was Rucharel (sorry forgot her name) the mother of the twins-

Hmm rurahel? ╮(￣▽￣)╭

No that’s no his guardian. That’s the twins mother who connected her life to his so he couldn’t kill her and blackmailed him to impregnate her. He gave his original guardian To the women he loved the empress who died and his guardian along with her

Yeah ur right(⌒▽⌒)
