*So it did hurt! Now that makes things better. It wouldn't have been as fun knowing that her target didn't suffer from all this pain, given that she put so much effort into making it all as painful as possible. Would've been a real pity if Kagayaki didn't even flinch from it, right?

The sudden decline of her offer to hit her with that Genjutsu a second time made the Kaguya grin.* "A shame... But eh." *She said in the end and prepared to be hit by a strong jutsu now. This was going to be interesting, as she assumed that this jutsu surely must be stronger than the original one. The Rock Gun.

Her eyes watched the kunai pop out of the ground. That's when she assumed a more balanced stance, moving her feet slightly further away from the middle to not fall over that easily from the soon incoming force. Though... Upon hearing his name, Kazuko's face showed perfectly how pissed the girl was now. Whether it was at Kagayaki or Ryusa was unclear, but the mood changed.* "Ryusa, hm?" *She mumbled. Loud enough for the other to hear. And loud enough for her to also hear how much anger and hatred she gave off by just saying his name.

Meanwhile, the clone just stared at the attack, as if the kunai was just a little pebble thrown by a child. Though the moment it got hit, the clone was launched backwards and crumbled into mud and rocks upon impact on the ground.*

Kazuko's reaction to Ryusa's name made the blonde hold back a smirk, "Still angry uh." She'd mutter instinctively, never one to be able to keep her mouth shut when she really needed. Her friend had valid reasons for her feelings of course, so Kagayaki understood.

"It needs to get even bigger." She'd say, throwing another one at the second Rock Clone. She was using the more fragile Kazuko's to get the technique to a point where it would actually be useful and only then test it on the real one, who she knew was about as tough as they get.

The kunai grew considerably, bigger than last time and about eight times as big, almost its max size and reaching almost a total length of two meters before colliding with the clone once again. 

"I'm saving the big ones for you! Think you can take them?" Kagayaki would shout at her friend with a large, playful grin.

"That fucker didn't show himself even once, so obviously I am angry, yeah!" *Kazuko yelled at Kagayaki for that one. This was one of the first outbursts in a relatively long time. Of course she was getting angry from time to time, this was normal behaviour for her. Kagayaki was definitely used to it and didn't seem to be bothered by it all, since in the end, the two still got a long. But this one was different. Well...

When the second clone popped, she did see how much larger the weapon was. Now this was a tiny bit worrying. Or would have been for other people. This girl here was not scared in the slightest, nah. Instead, she was just a bundle of anger and grumpiness, standing her ground as Kagayaki declared that the next ones were the big ones she reserved for the original Kazuko.* "How charming." *A snort.* "Of course I can take that shit!" *Though she didn't grin back, being still somewhere else with her thoughts. With somebody else, to be precise. Whether that was good or not... Anyway, her armour technique was up and ready. She was just waiting for the large weapon to come and get her, eager to see whether she would leave this training session with any injuries or not.*

Kagayaki herself did miss their mentor a bit, he'd taught her a lot and she'd like to see what he thought about her joining the miliary police, as well as simply talk to him again. Her feelings were obviously more platonic than Kazuko's, and the blonde still had a bit of a hard time understanding *Exactly* How her friend felt about the Saganohoshi. She'd found out it was best not to ask though, as she'd suffered slightly the last *Few* Times.

"We'll see!" She responded, before throwing the two kunais at the same time. The two expanded into their maximum size, ten times bigger than their normal one, as they rapidly flew towards Kazuko.

Despite Kagayaki's unimpressive upper body strength, the sudden increase in size would help her increase the shuriken's damage by a fair bit, though hopefully not tearing apart her dear friend. She knew the girl was incredibly resistant, much more than what her armors could ever be.

*Kazuko did indeed see Ryusa as more than just a mentor. He's basically her first friend, or one of the two first friends. Having had no friends before that, she grew much more attached to him than others probably would. Thus, having lost contact to him for such a long time all of a sudden, without any kind of warning or whatever, this whole situation was hard to handle for Kazuko. Given that she already lost her father forever, losing another close person was not going to happen. Not yet at least, and not this way.

The shuriken came closer and Kazuko, being the way she was, didn't just forget about it all and ignored her emotions for now. Nah, she instead took these feelings boiling up inside of her to then 'power up' her armour technique (if it was just that easy). The fact that this was an Earth Release technique made it easier for the Kaguya to tank it, but it did take a good chunk of her Chakra reserves to come out this thing unharmed.

In the end, she kicked the kunai away with a strong kick of her leg as it fell on the ground, having failed to penetrate her arms and chest. It didn't mean that the jutsu was weak, though Kazuko was just too moody right now.* "We done now?" *She asked, keeping her eyes on Kagayaki. She'd leave if the answer was yes, unless her friend wanted to hang out or whatever. To which she'd answer with a direct 'Yes' if food was included. If not, she might be hesitant.*
