[@BladeSS4] That be a bad idea son. These characters were on another level. Kusaru oozed chakra because she simply had too much of it - naturally, not through tailed beasts, but because she was just '2 stronk super OP'. Plot tool character that served as the main antagonist. 

Yamato was a character that somehow survived two roleplays and thus was also adequately powered up. 

He'd tear everyone a new one. I'd prefer to keep things somewhat on par with the whole 'new characters' thing, rofl.
