One fine day, when all of the Nogizaka members had news that every member have to move to the huge space to have their dorm room and went to the 2nd gen and 3rd gen go at the Nogizaka mansion and someone had greet them which is Master Yuri known as Shadow.
Master Yuri: welcome to Nogizaka Mansion my name is Shadow Yuri known as Master Yuri and I am the owner of this Nogizaka Mansion nice to meet you *gentlemen bow*
Suzuki: the 4th gen and 5th gen haven't arrived yet
Master Yuri: they will arrive in two days but feel free to walk around the mansion except for the bound area
Umezawa: sure we will feel free to walk around the mansion thanks
Master Yuri: excuse me I want to do something right before your dinner is ready to serve
Before Master Yuri had to leave the 2nd gen and 3rd gen member in the huge living room at the Nogizaka mansion while he bring some motorbike keys in his pocket and bring someone special to meet the Nogizaka member at the Nogizaka mansion went each of them happy that we had to move to this beautiful place like the richest mansion.
Yoda: there something is wrong with him
Kubo: what are you saying Yoda?
Nakamura: Yoda is trying to say is Shadow Yuri is a demon who disguises himself as human
Before Master Yuri arrived at the demon world and he can sense that Yoda Yuki know my true identity as a demon form but I can lie to them the same with the 4th gen and 5th gen member too.
Asphalt: Master Yuri...you worry about your human sister Nagi?
Master Yuri: yes what she hates me as a demon brother
Asphalt: you can tell her the true demon form as her brother
Once Master Yuri had arrived back at the Nogizaka mansion along with Asphalt by his side as his demon Butler and they know that he was a demon they didn't hate him or kill him but why did he want to know how to get us to move at the nogizaka mansion.
Nakamura: we know you are a demon and you protect your sister right?
Master Yuri: yes I am but she arrives in two days
Sato: did your sister know that you are a demon identity
Shadow Yuri shakes his head while everyone is still worried about Inoue Nagi and the rest of the Nogizaka members who had moved here in two day time to meet other.
Master Yuri: everyone needs to sleep by 11 pm tomorrow we can talk later
Asphalt: yes of course Master Yuri *bow*
Umezawa: are you feeling okay, Shadow?
Master Yuri went upstairs with Asphalt and the others are looking at him upset to have a word with Inoue Nagi by tomorrow went she moved here with the 4th gen member the same 5th gen member along with them.
Asphalt: Master Yuri you want some blood to drink your meal
Master Yuri: I'm not hungry and I don't want to drink anyone's blood but expect for my sister
Asphalt: you can't be serious about your sister's blood are you, Master Yuri?
Back inside the 2nd and 3rd gen dorm room together with everyone worried for Nagi that she finds out that her brother is a demon form for so long that he tries to protect her from getting hurt by other demonic people to hurt her in real life.
Yamashita: what is a demon eat for dinner or a meal?
Nakamura: demon drink blood on their neck but I'm not sure if they drink blood right now
Yoda: wait...did you that Shadow drink blood like human blood what are you saying is?
Nakamura Reno nods her head toward everyone who is here in the nogizaka mansion dorm room they were sleeping at the time 11 pm inside the room but once everyone is sleeping inside the dorm room and Nakamura can't sleep because she need some drink some water right before she can sleep straight way to the room.
Nakamura: who is there?
Master Yuri: oh just you Nakamura-san?
Nakamura: have you drunk your butler's blood
Suddenly, Master Yuri had fallen to the ground with his demon fangs coming out of his mouth while he panicked through his breathing and later a few hours later the member woke in the freaky early morning around 5 am in the living room by looking at Master Yuri who is breathing so heavy at his chest.
Yoda: what happens with Shadow?
Nakamura: Yuri didn't drink anyone's blood and he is rejected by Asphalt blood to drink
Ito: you have to drink someone's blood to have little energy left
Meanwhile, there have the 4th gen and 5th gen member who are here to move the nogizaka mansion in with everyone who is before them but they need to hide Master Yuri from them to find the truth about him so suspicious.
Asphalt: they are here in front of the door
Nakamura: can you walk Yuri?
Master Yuri: yes I can walk slowly
When Nakamura Reno was helped by Master Yuri to get into the hidden room just near the fireplace and suddenly they went inside and Asphalt was greeted on behalf of Master Yuri absent to greet them.
Asphalt: welcome to nogizaka mansion please come in and make yourself at home don't worry others had come right before you
Kaki: eh...why are there have the 2nd and 3rd gen members were here before us
Sugawara: I'm sorry where is Master Yuri to greet us did something wrong with him
In the meantime, inside the small hidden room and Master Yuri had become worse of all breathing that he need some blood to have a bit of energy to greet the 4th and 5th gen members in the living room with another member.
Nakamura: Yuri...please drink my blood
Master Yuri: I reject it to drink your blood Reno
Nakamura: wait...you can't go out there and they will find out that you are no longer a human Yuri!!
Out of the blue, the 4th and 5th gen members can see that we have Master Yuri who was hidden in the room with Nakamura Reno who was afraid to see him in a demon form in front of the few other members who had reached here at the nogizaka mansion.
Nagi: nii-chan...you are alive but why did you become a demon?
Asphalt: Master Yuri you need to drink something right before you went to deep sleep forever
Kaki: Yuri senpai please drink my blood I don't want you to faint half dead
Without any sound coming from Master Yuri and he use speed toward Kaki Haruka's neck she lifts her hair and let him suck her blood right in front of the nogizaka member who is still in shock with Inoue Nagi's demon brother who had been missing over the past years before they got some news about look like him as Master Yuri.
Master Yuri: that's enough for me to drink your blood, Kaki
Kaki: it's okay but now you can go back to sleep
Master Yuri: sure...*collapse*
Inoue Nagi had rushed toward her demon brother and she even look the same as her old brother in junior high in the perfect outfit that he was wearing the school boys uniform as the Hinatazaka Academy all-girl school.
