@Halvtand That is a very helpful critique. Stress in the real world, but until I work on the sheet:

- Regarding Kumo origins, I realize you're correct. It was sort of like an artifact from an earlier version of his history, that I tried to fit into the new idea. It could potentially add some intrigue when I don't have anything going on with him, but really, a mercantile family does that anyway, plus the interest in his dad.

Instead, I like your idea for a Gobi family who traded with Kumo before those relations died out. I'll keep the Shikawa name and darker skin.

- You also make a convincing argument for a C-Rank jutsu; especially since it might have grander uses. I'll adjust the data.

- I got the impression Konan's jutsu morphed the actual paper, rather than just bending it. Still, Masakazu having this does seem potentially unnecessary in retrospect. I'll get back to you on this.

- As for the (lack of) testing, I will think about a suitable way Masakazu might've demonstrated himself to Hyuuga.

I'll probably add some small amount of weight, but he doesn't need another chakra nature. I imagine he only has a basic grasp of fire anyway.
