"Is it now? How peculiar."

Though he supposed for them he had merely shown off his abilities and then avoided her own. She had yet to truly be initiated into the Senju's style of combat, but that was perfectly fine at the moment. There was nothing she had trained that really required him to utilize his usual intensity, especially now than she was basically practicing chakra based calligraphy. 

"You truly are not deep enough into this craft to where you should be thinking about things such as theory, are you creating your own never before seen seal? If not, you are merely learning to copy the language of seals. Memorize the proper pattern and move on."

Unless one was starting to become Minori, Ryoshi, or Toro, there was no need to overcomplicate things to such an extent. Copy what is required and move on, that was what he did currently anyways. Though that was because he did not need such an extent style of seals with his ninjutsu.

"Oh don't worry, I'm not trying to do anything as advanced as create new seals." *Using her free hand she removed a Kunai from her pouch, holding it up towards the Senju.* "I'm trying to seal this, that's all. I admit I may have read some more advance material than was necessary for what I want to do but to be honest I'm trying to impress someone."

*She looked at the scroll, placing the brush to its surface. It took an immense amount of focus for her to not shake her hands. Making one mark she removed the brush again.* "No, that's not it. No look to be honest I'm just worried that I will mess this up. Compared to ninjutsu this is so complicated." *Trying to ignore any doubt she had, the brush once again began to move on the surface of the scroll. After a few moments, she had finished her attempt at a seal.* 

"Well then, is there any obvious issues with this?"

"Not really, you are practicing calligraphy and then flowing chakra through it. That is the basics of what you are doing, after that your goal is to make your seals as small as possible."

An example would be the kunai he now withdrew, the kunai which would have the exact seal she was trying to create inscribed on the four faces of it. Yet, this was only the most basic of seals one worked with. Well, it was also a velocity seal that could be triggered by coming out of another seal, but the original part was still fairly similar.

"It's nothing too complicated, copy, like letters."
