"Waaah!! Chi-kun!!" She extends a hand out when she sees the poor boy run to the bathroom. Oh, squid and octopi were definitely ruined for him forever...! "P-Poor baby....maybe I better not cook him any seafood for a while...." Probably not even fish, despite it being safe... for the sake of his poor stomach.
"............" This one.... she turns back towards him. "You." Even after making Chihiro so sick he had to go throw up, he's still boasting about how he won! She can't believe him!! Much as she wants to bite him or lick that horn, he will definitely throw up Marogareh as retaliation! And she's being spared from that, so she can't take risks....
So instead, with a big puff of her cheeks, she crawls closer to Naoki, straddles his lap, and grips his shoulders before she starts shaking him furiously!! "Naokiiiii!!!! You big dummy dummy dumb dumb!!! That was soo mean!!!" Shaking him, shaking him, shaking him! "Making poor Chi-kun throw up cause you wanna be right soo bad! He didn't deserve that!! You better apologize to him and his poor stomach, okay?! Or else I'll... make the taaaastiest takoyaki and calamari...and eat it riiiight in front of you and not let you have a siiiingle bite!!!"
Now she's tugging his cheeks. He may have won in the end, but she still has to get payback for poor Chi-kun!!
