@eaglejarl, that was fucking awesome. You did an amazing job with that one.
So guys, I just had another clever idea, this one to help with Hazou's chakra pool problem.
Here's how it works. You make a small waterproof storage seal. Then, right before battle, you fill it full of chakra water and swallow it.
Yes, you did just read that correctly. You swallow a storage seal full of chakra water to release it inside your body for more chakra as needed.
The downside is that the chakra water doesn't keep for long outside of a barrel, thus the need to prep it right before a fight. But that's perfectly suited for a tournament environment.
As for activating the seal, if the seal is inside you then I'm pretty sure that counts as touching it.
Just need a method of waterproofing that isn't toxic and lets the seal remain flexible. Drawing it on something like linen instead of paper might help.
