There has been something hidden for a long time that neither the vampire family never knew. Especially for Karlheinz before Yui moved in the Sakamaki mansion. What Yui forgot, is herself being a puppet princess. A rare ability for puppeteers to be able to control marionettes or dolls with some kind of magical finger ribbons that summons magical strings. In addition, they put a little bit of they're soul in them. Though, this heroine maybe naive, but she has been living her life to endure all the pain she could get from the vampire's. One night, she was hiding herself in her room not wanting to see the sadistic vampire brothers. She couldn't use the silver knife to kill them. But she can't do that. She loves them as if they were her human family. That night she was in her room, she knocked one of her suitcase and found something. Her dolls, and her ten magical finger knots that controls them. Would Yui be the same weak person? or will she be able to protect herself with puppet magic? Find Out!

"Oi! Get your hands off Nee-San, your bastards!" "Ah, Yuu-Chan, calm down please. There is no need for a confrontation." A small smile forms on the blondes face as she lowers her head in greeting. "It's a pleasure to meet you all." Lyra Komori is a kindhearted girl who acts as a motherly figure for her adorable-and-sweet-and-lovable-and-cute, little sister. When she and Yui are sent off to live with a family friend, what could possibly happen? Little did they know, both girls find themselves living in a mansion with six vampires who crave their blood. Maybe. Lyra's wheelchair might actually make the experience a little more awkward... Featuring a badass and protective Yui, a kind and motherly OC in a wheelchair, some science-related career choices that should technically be illegal, reincarnation, and the poor Sakamaki family who suffers through the shenanigans because, for sadists, they are arguably scared shitless.
