Would the Chinoike still be alive at this point. If so I think it would be helpful for kirigakure to invite them to join their village as they would gain a dojutsu clan and it would give the mc an extremely loyal clan.
I must confess that I never researched Kisame's clan. Even though he is in my top 3 favorite characters in Naruto, I was surprised to learn that it is a kind of lineage to be half "merman" and so on, by the way, very good chapter, keep it up brother!
