He healed her loneliness

The first kill!

The next day Yuki and Kazuo had to head back to school where the first few students die way before she kills her best friend Ayaka, before going in she stopped in front of the doors.

"Yuki? What's wrong?" Kazuo asked her.

"Nothing, you must go to class and be ready for what's about to happen." Yuki said looking at him.

"Ok I guess this is how it's suppose to be." Kazuo said understanding a little then he left.

After he left and she followed a bit later in class she spied on the other girls before class started and then she asked to go use the bathroom then that's when she put that note in the girls locker,  she simply repeated the same thing she did before and just went on with the day after doing so. Later during lunch she did exactly what she did the first time, doing everything the same but instead changing it up a bit.

After school she took the girl back to her home in her basement and Kazuo was with her.

"So is this what you do to some people?" Kazuo asked her.

"Yes I bring them here and...well you know the rest." Yuki said smiling at him.

"Right...so what are you gonna do to her?" Kazuo asked her.

"We're gonna have to kill her as soon as she wakes up but this time I didn't use the tranquilizer I just knocked her out myself." Yuki said explaining.

"We don't have to do this Yuki..." Kazuo said looking at the girl feeling bad.

Yuki pushed Kazuo up against the wall holding a knife to his throat, she looked at him angrily.

"I'll kill you too so I can have you quietly by my side." Yuki said looking at him.

"Yuki if you kill me you'll still be alone, you'll still be lonely without any by your side." Kazuo said looking back at her.

She stared at him for a little bit then backed away giggling as he liked confused.

"Yuki what's so funny?" Kazuo asked confused.

"Your really funny Kazuo!" Yuki said giggling.

"Thank you? Yuki...are you gonna kill her?" He asked confused.

"Kill her? Why would I do that Kazuo? She's our guest!" Yuki told him and gave him a smile.

Later they went up to go have dinner and while they ate they were both silent for a really long time.

"Now then I shall go." Yuki said getting up from the table.

"Where you going?" Kazuo asked her.

"It's time for that girl to die!" Yuki said smiling at him.

She went back to the basement with Kazuo following her and once they got down there she stabbed the girl like if it were nothing because to her it was normal since she has to keep Kazuo safe all to herself.

"Yuki....how do you feel about this?" Kazuo asked her.

"I feel great! Doing this is great because I'm protecting you from anyone who tries to take you away from me." Yuki said explaining how she feels.

"Yuki.." Kazuo said looking at her.

"Well then we shall get ready for bed, we have school tomorrow." Yuki said turning away to head back upstairs but instead Kazuo stops her.

"Yuki wait!" Kazuo said getting her attention.

"What is it Kazuo? Something wrong?" She asked him.

"I've always thought you were creepy..and weird but every time I looked at you I see that your actually hurting from what everyone says about you like calling you names, I was afraid to talk to you or get near you because I didn't know what you would do to me." Kazuo said explaining as he looked down making a fist with his left hand.

"Kazuo..." Yuki said surprised of what she's hearing.

"Now that you've told me everything about how those students died...and why you do this, I'm not afraid anymore I want to protect you just as much as your doing for me." Kazuo said while she turned around to look at him.
Kazuo got down on one knee and took her right hand kissing it.

"Yuki Shiromiya from this day forth I Kazuo Yamada will protect you and will always be by your side, I want us to have a happy ending together." Kazuo said looking up at her.

"K-Kazuo....I-I...I love you so much!" Yuki said crying happily as she got down and hugged him tightly.

"Together let's kill them, my friends and your best friend let's do it together Yuki." Kazuo said holding her.

"Yes Kazuo together let's kill them!" Yuki said looking at him.

He carried her upstairs to her bedroom and later they got ready for bed, they got into her bed already going to sleep but she stayed awake thinking about the things Kazuo had said to her.

( Kazuo....he makes me feel really special, he's my reason for still being here because I love him so much. I feel like I can do anything with him by my side and together we'll have a happy ending, or if I die I want to die happy knowing that Kazuo Yamada accepted me. )

She smiled to herself and looked at him then she fell asleep after turning the light off.
