Gaiden 700.1 Book of Thunder=Kiba and Akamaru Chapter released.
So, these are official it seems.
700.2 is the one with Kakashi and his revealed face. I'll post that in another thread.
This one is weird. We see everything from Akamaru's POV. And he's swearing lol and Kiba meets his unknown love interest.
