...second half of the synopsis is so fucking stupid. I'm so mad. I refused to read this for so long because of it.
A Possesser from another world, a Regressor from the future and a Reincarnator from the past all walk into a mansion...
...owned and operated by the FL, another possesser, only she's from the same time period as her new body. Oh, and her new body and family's real, literal God-given purpose in life is to be the counselor/therapist/best friends/tour guide/life coach/babysitter/live GPS/safety blanket for the above kinds of "special guests".
It's her new family's sacred duty passed down from the Goddess of Time and Civilization for a millenia.
Too bad she's broke as hell and was literally one day away from selling her mansion in the city that has no guards, no servants and she's unable to maintain or afford its upkeep.
Enter the 3 "special guests"!
If this was the blurb instead I would have been aaaaall over this.
Blue-eyed, white haired Crown Prince is the transmigrated Possesser from an Earth that's overrun with monsters. He's got a System and was a "regular" college student. His real identity was being the number 1, very mysterious Hunter of his time.
Cold and distrustful, he only wants to go back to the ruined Earth.
Red-eyed, black haired Heir to the Chairis Dukedom is the Regressor. He was a bloodthirsty, cold, murderous "demon" of the battlefield in his first life after his family fell to ruin.
He's now a puppy dog, scared and sad and pathetic, self-doubts cripple him because of how normal life is right now. He doesn't want to mess up his second chance. He's so used to killing and misery that he can't adjust very well though. Suffering from severe PTSD.
Ash brown hair and eyed Reincarnator is a genius administrator in the Imperial offices. Unassuming and physically forgettable he's also the reincarnation of the blood mage that the Empire's founder fought.
The blood mage wants gory revenge and the Empire's complete annihilation. The administrator just wants a quiet, boring life. The blood mage keeps trying to take control and a lot of the plot line evolves around this guy.
