Kaigaku's pov:

I walked to my room and sat down on my bed when I heard yelling from outside my door.

"COME ON BROTHER ITS NOT HARD YOU HAVE TO DO IT EVENTUALLY!"

"DAKI YOU HAVE NO IDEA HOW HARD IT IS FOR ME!"

I stormed outside to see gyutaro and daki yelling at each other.

"CAN YOU BOTH SHUT UP!" I yelled.

"O-oh Kaigaku" gyutaro chuckled rubbing the back of his head. I looked at daki who was smirking at us "Daki why are you smiling like that?"I asked "Ohhh nothing~" she chuckled "Okay then... anyways why were you fighting outside my room?" I asked gyutaro stiffened up immediately "U-uh no reason" I raised one eyebrow "oh yeah well there must be some reason" daki opened her mouth to talk when gyutaro said "You know siblings fighting all the time hehe" I chuckled a bit "Yeah I do" daki stared at us again and smirked "Hey kai" I hummed in response "My brother wants to invite you to hang out with him later on today".

Gyuatro seemed like he was about to kill his sister when I shrugged and replied "Sure I'd love to!" he stared at me speechless while daki once again smirked and chuckled "Alright! since he can't talk right now for some reason how about you meet him at this place at 11:30 pm" she handed me a note and I looked at it and nodded. "Okay then see you later gyutaro bye daki" she waved me goodbye as she pulled her brother away.

Gyuatro's pov:

Daki dragged me back to our room and as she closed the door I yelled "DAKI I WAS SUPPOSED TO ASK KAI! WHY IN THE WORLD ARE YOU BEING MY WING GIRL!" she laughed and put her finger against her lip "Oh don't you worry anyways you to get into better clothes" I stared at her "Yeah like anything is going to suit me and my tea cup waist" she laughed and sighed "I'll get you an over sized top to cover that" I rolled my eyes and sighed "Alright then".

A few hours later daki came running back to me yelling "BROTHER I GOT THE CLOTHES!" I sighed and asked "Okay what is it" she put her hand into her bag she had and pulled out an oversized green jumper with bangy blue pants to go with it. "Wow I'm actually impressed, good job sis" she smiled at me and chuckled.

Kaigaku's pov:

'UGH WHAT DO I WEAR!' I thought throwing all my clothes on the floor "WHAT THE FUCK!!!!!!!!" I yelled at the top of my lungs. "Kai? you alright" I heard muzan call "NO!" I screamed he walked in and patted my back "What is it?" I groaned and threw myself on the futon "I don't have anything to wear...." he looked confused "What do you mean your outfit is fine why are you worried?" I explained everything to him and he clicked his fingers and a blue top with black pants appeared in his hands "Will this be okay?" he asked I smiled and hugged him "Thanks dad!"

(Kokushibo and muzan are dating so since kokushibo is like a farther to Kaigaku, he calls muzan dad)

"Your welcome" he said as he walked out of my room.

At 11:20 pm

'Okay! human blood to keep my hydrated check! human meat just in case any of us get hungry.. check! flowers to thank him for inviting me... check!' I sighed as I looked at myself in the mirror.
