My anime routine in FGO

My name is Hyakki Ryuji, I am an ordinary Japanese high school student and the master of Chaldea.
After successfully restoring my human nature, I returned to my daily life... What a ghost!
There is a little girl in the family, what the hell is Shaking Dragon, and she has to face the poisonous tongue of her seniors and ministers every day, she has a childhood sweetheart with a very low sense of presence, and she has to take care of a pet girl who doesn't understand anything and an erotic artist sister who lost her mother !
God, is this the daily routine in the legend? I think it is more reliable to restore human reason! !
