Kagayaki felt herself be dragged, "But I though-" She was interrupted by Kazuko's declaration that she was gonna beat Kagayaki and the blonde laughed, "Of course you're gonna beat me I'm all skin and bones." She joked before coming to a stop with Kazuko staring straight into her eyes.

She smiled gently, even if Kazuko told her not to see it as a nice gesture she was going to. Even if she was still forcing her to spend money on something she found rather unnecessary, she couldn't bring herself to refuse the other's offer, so she went along, "Aye, aye, whatever you say." 

She gave the Akimichi a small nod with a smile as he greeted them, her eyes wandering around to try and spot Hachirou, her Akimichi friend - sadly it didn't seem he was around. She chuckled at Kazuko saying they were gonna fight, frowning her eyes, "I can handle more than the Beginner's race, bring us the step above from that one!" She declared, as competitive as ever. She'd pay Kazuko back, eventually.

*Kazuko snorted.* "I know. I'll maybe go easy on you." *On second thought, she shrugged.* "Maybe not." *A cheeky grin. A total opposite to what Kagayaki gave her, which was that gentle smile once more.* "Meh, stop that." *The free hand came closer to her face and she gave the other a few gentle-ish slaps.

After they had sat down and ordered, the words of the other girl made Kazuko stare at her. Wait, what? This little shit is challenging her now? The Kaguya leaned in closer, keeping up the stare. It was intense... Would she start eating her alive now?!* "So that's how it is, huh?" *She got a punch on her arm, and a smirk on top of that from the bone lady.* "Brave, but stupid." *At least she admitted that Kagayaki had guts for that!

As the Akimichi nodded and went to the kitchen, the two had to wait a bit until they'd get their food. So Kazuko just let her head rest on the table, letting out a long and annoyed sigh.* "That's the worst part." *She complained with that grumpy tone of hers.*

"Eh, at least I'm brave." She commented, shrugging and rubbing her arm from the punch as the other slouched on the table. She smiled and reached out, giving the other a joking pat on the head. "There, there..." She said, knowing an out-burst was coming her way.

Kagayaki had a short fuse for certain behaviors she had to admit, but interacting with Kazuko was surprisingly freeing. She expected the other person to be rude and aggressive, but to later be kind in her own way - so when the insults and aggressiveness came, Kagayaki would be less angry and more curious and expectant to see how Kazuko would act next. It was fun.

*She wasn't whining more, but her facial expression did show how annoyed and 'sad' she was about that waiting part. Only when she suddenly received some pats did her eyes look up at the hand that touched her. And the weird thing was: She didn't react at all for the first few seconds. No movement, no resisting. Just kinda... Accepting it? Could it be that she like-

Aaand there she went growling, raising her head to genuinely try and bite Kagayaki's hand. For real!* "Asshole, what were you-" *Nevermind that, food is ready! Just like that it seemed to stop her anger, since the Akimichi came with all sorts of meat on two separate plates. One for the angry Kaguya, the other for the smiley Ressha. It honestly looked like they were served two little mountains of food. Kazuko's face? No anger whatsoever, but rather excitement. Big eyes. Almost shining, it looks like.* "Here you two go! Are you ready?" *His hand went up.* "Set..." *Kazuko looked over to her opponent with a wide smirk, poking her cheek with her finger - specifically its nail.* "Don't throw up, idiot!" *And then...* "Go!" *And what they could see was Kazuko starting to eating for her life. But it really looked unhealthy, or just strange; did she even chew the food?! One piece after another, it was as if she didn't eat for a looong time. As if her jaw was unhinged and all the food fell down that tunnel.*
