Thanks for the chapter and i feel like having the charak mode for the nine tails only(i forgot how to spell his name) is dumb so if the MC and eventually other people with tail beasts (forgot how to spell that too) share their charak it should be possible
also isnt there a more powerful variant like naruto's like there is the nine tails chakra mode(golden one) then there is the kurama chakra mode which is much more powerful because if your doing this then shouldn't there be one for isobu.
let me know if i am wrong
