*As she listened to what the technique was supposed to do, Kazuko raised an eyebrow for a second before just looking rather unimpressed.* "So it's the Rock Gun technique but with a different shape?" *Were her only words. Words coming definitely from her mouth: Direct, with no filter. If they hurt the other person or not didn't matter to her it seems.*

"If you wanna. Stay inside of it long enough to at least tell me what you saw." *She explained before the Genjutsu was cast. And when it happened, the Kaguya watched with curious eyes as the other started to groan and fall on her knee. Huh, so it was working after all. She even squatted down and stood in front of her friend, staring into her eyes while waiting for the Genjutsu to be broken.

When that happened, she stood there in that pose, put her elbow on her knee and rested her head on her hand.* "So? How much did it hurt? You couldn't move, right? What did you see, hear and feel?" *All this stuff was important to her so she could make sure that the illusion itself was perfect, else it'd be too easy to notice and break out of.*

"Well, it's like a more terrifying rock gun where I can combine my shurikenjutsu abilities with it." Kagayaki explained, Kazuko's question was somewhat valid, as the technique was a combination of Rock Gun and Earth Arsenal, it was however much more powerful than rock gun, as she could easily make shuriken curve in ways rock gun never could.

Kagayaki would stay in the genjutsu for a bit, her endurance to pain nothing to scoff at. When she did broke out she kinda sat down. It was a nasty experience. "Well I didn't really see anything, just heard and felt all my bones crack and break. It was pretty painful." She explained, rolling her shoulder slightly.

*Kazuko nodded in the end, seemingly just a tiny bit more impressed than before. Eh, she was just busy with eating and training, so she probably didn't care about anything else during that moment, meaning no offence to her friend.

Regardless of how enduring a person was, getting almost all of their bones broken was not going to be a sensation one could easily shrug off. And usually, it wouldn't matter to a Genjutsu user that much, as long as the target is paralyzed when the jutsu is supposed to do that. But Kazuko was totally living to see her target suffer in their little illusion.* "Hmm... Good. As long as you couldn't move and it hurt you like hell..." *One glance to her friends limbs, then back to her eyes. The Kaguya gave off a long, rather quiet growl. Well, it wasn't a growl really. She just was thinking loudly.* "Seems like it didn't hurt you enough though. Might have to change things."

*Kazuko in the end just shrugged and stood up, taking a few steps back with her arms extended, as if she was demanding to be attacked.* "Come on then. I should be done with my jutsu, unless you wanna get fucked a second time." *A small smirk and after gaining a few meters distance, she stopped and let her arms drop. And for the purpose of giving the other a chance to use her Shurikenjutsu abilities, she summoned two Rock Clones next to her, who then also walked away to spread around. The original Kazuko activated her armour technique.* "Try me."

"It- it hurt quite a bit really." Kagayaki said, struggling a bit to stand up, the sensation still lingering slightly, though it was purely psychological. She would shake her whole body, trying to get rid of it. Genjutsu never failed to impress her, the things one could do with it. Kazuko had made a rather interesting one, given her heritage.

"No, no, no. I'm good." Kagayaki would say with a chuckle and a wave of her hands. At her friends offer she'd grin, "You're on." She'd move her hands quickly, almost a blur. It took her a moment to conclude all of them however, the molding of her chakra still somewhat slow, despite her increased control.

Once she was done, she slammed one of her hands down into the ground. Four kunai hilts shaped up from the earth bellow the two, peeking over the grass. Kazuko might be familiar with the foundation of the technique- Earth Arsenal. "Ryusa taught me half of this." She'd say, knowing their common mentor was a soft topic for the Kaguya but mentioning him anyway.

She grab the four kunais from the ground and she could feel her chakra inside them, wanting to expand. It seemed to be kind of working for now. She threw one of them towards one of the Rock Clones, the projectile curving before suddenly growing. It only grew a few times its size, becoming roughly the same size as a sword before colliding with the clone.
