Well this brought back memories. Akane remembered, albeit blurry, the time Jomei had threw stones at her like she was some witch. Of course, it was actually just a method to train the two's reflexes and earth release skills respectively. Ah... Anyways, Akane would nod firmly. "That'd be awesome!" The redheaded girl would shout out in response. She'd grown to love training with others, it was always the most fun. "Give me a moment, I'll clear out some space between us, then you just tell me when I should start."

*Immediately getting to work on the technique she was going to learn. She started by weaving the basic ball of rubber, it was the simplest shape she could achieve due to rubber's latent and natural properties. The difficulty of the kekkai genkai came from the shaping it into other forms and objects, as well as tweaking whatever properties it took on or enhancing them. She had expunged the rubber from her hand and aimed it directly at her torso.* 

*It didn't take long, before she knew it she had a cylinder around her torso, encapsulating her arms and shoulders all the way up to her neck. This wasn't what she intended to happen, but for a first time she could think of it as a proof of concept. Now it came time to actually to get hit by an attack, whatever it was she had to be prepared. Which is why she was half expecting to need to use an earth release technique by weaving hands within whatever small amount of free space inside the cylinder to creat Earth Shore Return.* 

"Ready when you are."

Is that... Rubber? What type of style is that?! Witnessing what she witnessed, the sight had bred numerous questions within her mind. It wasn't often you saw someone with rubber release so it's to be expected she had never seen something like this before. Okay, well it didn't matter. They were here to train, if she was training rubber, she was training fire. Not much to it. She readied herself, much like Jomei did. She stared down her opponent, wondering if she would have to face in the founders one day... Before promptly weaving her seals. She had overcome her overthinking a long time ago, she wasn't about to start again. "Fire Release: Great Phoenix Fire!" The girl would shout out as she finished weaving the seals, a breath of flame taking the form of an aviary beast swooping in straight at Jomei.
