*Present Day*
Yoshino Snr and his friends were having a blast, music was playing in the background and their wives/girlfriends were in the kitchen laughing.
Hikari was at his grandmother's house while the triplets were out with their friends.
*doorbell rings*
The housekeeper answered the door and smiled, she let the woman in that rang the doorbell. It was Yoshiyuki, she looked a bit ill and greeted everyone. When she went into the kitchen, she greeted the women too, out all of them, Erina was the only one who greeted her back.
Yuki did not mind this because they were all irrelevant existences. She returned to her room and typed a text message on her phone then pressed send.
Her eyes slowly closed and a few minutes later she felt her phone vibrate under her pillow. She took the phone out lazily and from underneath the pillow, swiped right and read the message.
She placed the phone beside the bed on the table and pulled out a black bag from under the bed. She unzipped the bag and fiddled around and pulled out a gas mask. She locked her bedroom door and put the mask on, then laid down on the bed and closed her eyes.
After 15 minutes passed, she could hear screaming inside the house and but the screaming didn't last long before the house became silent again.
She turned her body over and saw the gas seeping through from under her bedroom door and sighed, getting up from her bed she walked over to the door and opened it.
Her father was laying on the ground in front of the door. Before Yoshino ran to her bedroom to try and get her to come out but it was too late, the gas was too strong.
The house was filled with gas!
She stepped over her father's body and walked to the kitchen, a smile appeared on her face as she saw how they all were laying on the ground.
She then went to Aria's room and picked her up, she tied Aria up and placed her in a room with Okino and Yui who were tied up too.
