Yuki
"Yay! Now there are more people ...." Yuki was smiling happily, before her smile turned sinister, "who I can poison" she added with a malicious tone. She really did mean who she could poison, of course it was the neurotoxic type, the paralysing one. Most of her pranks were more dull without the poison. Some were ridiculous, such as paralysing them and hanging them off a tall building. That one was ... something she won't do for a while though.
Seeing Flint approach the stairs, Yuki went to pick him up again, only to be stopped by the length of his arm. "Come on! There's no need to be embarrassed, it's quicker!" she complained to him. Pushing through, without using her powers, she couldn't reach. She then thought to try tickle his fancy a little. Looking up at Flint with puppy dog eyes, "Onegai~! Flint Onii-sama!" She tried looking cute and using a little sister attack. Waiting for the response from him. If he would accept or let his guard down even fro a split moment, Yuki would pick Flint up and then start to jump down to the ground. Otherwise, follow him down the stairs, pouting.
Seikou
Hearing Akane ask if they could go, Seikou turned to her and nodded. Walking towards the door and out of the building. With his one eye, he looked up, in the direction where Flint and Yuki were supposed to be. But he could no longer see them. Looking around, they hadn't reached them yet. Is she going to drop down in front of us again? he thought, being prepared for any dust and dirt coming up to protect his one "good" eye.
