Headcanon #8: Kaito has 3 older brothers, 2 elder sisters, and one little sister. This is how he knows the different ways siblings interact, chaotic.

"You all need to spend more time together!" Their Dad yelled and slammed the door.

"You mean you want to go on a date with Mom but we're in the way." The eldest child and sister, Kiyomi, rolled her mint green eyes and pushed her blonde hair back.

"Kiyomi!" The second eldest, Haru, yelped, mint green eyes flickering back and forth with worry and amusement as his shaggy blond hair fell in his eyes.

Yumi, the fifth child, snickered as her brown hair tickled her cheeks, blue eyes flashing.

"Of course that's we he means, idiot." Ryo, the third child, rolled his blue eyes and pushed a hand through his blond hair.

Kiyomi glared at him as he smirked back at her.

"Both if you knock it off." Hiro, the fourth child, snapped as he glared reproachfully at the door, mint green eyes glinting as brown hair fell on his face.

"You guys never want to hang out with me!" Aina, the youngest whined loudly and stamped her foot.

"Because you're a baby." Yumi said in disgust at the middle schooler.

"Am not!"

"Are too."

"Not!"

"Too!"

"Shut up! I hate you!" Aina wailed.

"Kaito, get her to stop crying!" Haru pleaded.

"Hey Aina, guess what?" Kaito sighed.

"What?"

"There's a dragon guarding the beloved Princess Ice Cream from our clutches!"

"I'm not a kid!"

"But you want ice cream don't you?"

"Yes but-"

"Then act like a freaking kid."

Headcanon #9: Tamaki had dragged the Hitachiin twins to Ouran High School during their third year of middle school to meet Kaito who he was certain would join the club, they immediately took to him.

"Um hi?" Kaito waved nervously under the gaze of amber eyes..

"Which one are you saying hi to?" They asked in unison.

"Both of you?"

"But which is which?"

"Well I'm not going to know on our first meet." Kaito rolled his eyes. "I don't even know your names."

"I'm Hikaru." One said.

"I'm Kaoru."

"Then I'm Kaito, it's nice to meet you." He said with a little smile.

"What are you doing?" They asked.

"I'm setting up traps." He said simply, tying a clear rope to the marble pole.

"Why?"

"Shhh, just watch." He smirked and hid behind a pillar.

Yasuchika was running down the hall, "I HATE YOU TSUKINO! I SWEAR WHEN I GET MY HANDS ON YOU-" and that's when he tripped on the wire, which caused him to bump on a table spilling water he slid on, which caused him to sail into the girls restroom.

A series of screams and "pervert!" echoed before a red faced Yasuchika ran out with a nosebleed.

Kaito smirked and sat back.

Glancing up only to startle at the looks on their previously blank faces.

"That was amazing." Hikaru whispered in awe.

"Senpai! Teach us your ways!" Kaoru added.

"Guys, I can't just teach you-" their faces fell and his smirk widened, "-until you promise to use them on Kyoya and Tamaki."

"Yes senpai!"
