I do wholeheartedly believe Shiori Novella is a sick sick freak. I like her streams but I definetely think this chick has like a hidden room in her stray cat filled apartment that she slips into quietly each night and it is just filled with porcelin doll replicas of all the Hololive members and she puppets them around mimicks their voices and shit. And sometimes she'll dm Nerissa pictures of her little doll with a comb or something from an anonymous account and pair it with something like "see how I take care of you, Narissa?" and the the following day Nerissa will hop in video call and go, "Geez, Shiori, look at this," and Shiori will pretend to be all concerned and horrified but there is this calculating almost eager look in her eyes that unsettles Narissa. And then when Shiori is hosting Advent's first big off-collab at her apartment, maybe Nerissa gets lost on the way to the bathroom and finds that little room and see all those dolls and her throat will hitch in horror. And before she can call out to Bijou or the twins to take a look a dark silhouette will appear in the doorway and Shiori looks sort of resigned when she says, "I see you finally found my secret, Nerissa," and Nerissa will try to pretend that she's fine with it but they both know better. And Shiori will say (the look in her eyes again) "We both know this can't get out, right?" and she'll grin very suddenly and Nerissa will laugh along very nervously and leave the room and eat some pineapple pizza and when the off-collab is over she will rush outisde and frantically try to contact a taxi but over the concrete of the street there is footsteps. And tears are running down Nerissa's cheeks but she can't say a word and Shiori, emerging from the shadows, will gently touch her on the shoulder and say, "look, I'll drive you to your hotel, huh?" and Nerissa will try to refuse but they both know it's futile. And halfway through the drive, Shiori will smile and say "I'll miss collabing with you" and then perfectly jump and roll out of the car, wiping off her skirt, while the car swerves into a local Hot Topic, bursting into flames.
