Welcome to Gaia! ::

Grass was never created here so they technically have no styles, and sound is....well very peculiar. In the sense that technically speaking, the sound kage is walking around currently doing just fine. I would assume the RPC as acting kage probably has most if not all of their styles on hand. It would however, take you ascertaining just who the shinobi is, as well as convincing them to allow you to learn their styles. The sound village in this guild operated on a whole other level of the term "shinobi," so at times finding this information would be difficult.

As for personal styles, those are meant to be kept to the owner and no one else. Should they wish to teach them to another they can, otherwise the style remains an RPC specific style. However, I will say that I am working on releasing a lot of those personal styles as arcs in the future. Figure if the style exists and it's good but no one is using it, throwing it into the shinobi world with the intent of basically any RPC coming across it wouldn't be that bad.

As for how training works, this is something I'm currently working on to fix. Normally speaking, you would have to learn each stage of a style at its rank with training requirements. While most styles list training requirements per stage, some seem to have faltered in this regard. I would say your best bet would be to name the specific style and perhaps PM myself so I could come up with at least the genin-chuunin training methods. Provided your RPC is a genin, that should be enough until I have actually fixed the village styles and what-not.

We've been trying for years to cut down on the number of custom weapons with effects for all elements, so probably not. If you're talking about Asuma's trench knives, the wind effect, as I understood it, was more a jutsu than any trait of the knives. Even if it wasn't in canon, we'd prefer if you did something like that instead.

Yeah sorry about that Hado. When we opened and subsequently for the two years after, you have no idea how many elemental weapon apps I had. If you look in there, at one point I got frustrated and outright told people that I'd start denying them. The reason was because everyone wanted a weapon that covered all their bases, which meant it basically had a jutsu for all their elements. In the end, you're basically just making jutsu and channeling them through your weapon. I wanna see unique weapons, not just jutsu based ones.

Hell, my first weapon is a katana comprised of 1,000 senbon intricately kept in place by chakra, that can be broken apart to use the senbon via chakra strings. No jutsu techniques, just interesting.
