50 parts Complete Queen Beryl, the notorious villain from Sailor Moon, wakes up in a strange new timeline and finds herself as the mother of Usagi and Shingo, married to Kenji Tsukino, and is even called "Beryl Tsukino"! Completely confused, Beryl has to pretend to be a good mom while she tries to figure out what the heck is going on.
She discovers that she doesn't know anything about being a mom, nor does she know much about normal human things, leading to many comedic moments as she tries to acclimate to her new life. Meanwhile, she's being closely watched by Luna the black cat who just won't let her guard down.
As Beryl tries to understand her new life, she also contemplates whether to be her old self - cold, rude, and uncaring - or try to be better. She even begins to feel a strange warmth in her chest as she observes families spending time together.
With Luna biting at her feet and Kenji constantly checking on her, Beryl desperately tries to get back to her original universe. But for now, she's stuck trying to play by the rules until she figures out how to get home.
