How a Realist Hero Rebuilt the Kingdom 13
When will you start translating Realist Hero 13?
Volume 13 was released in Japan on September 25.
The previous thread on this topic guesses that it would be 2 to 3 months after it releases in Japan, which would make it at least the end of this month, and perhaps next. Note that's a guess from another user, so take it for what you will. I know JNC licenses each volume separately unless they're catching up with something that's already out, and they have a policy of not talking about licenses that haven't been completed yet, so unless they've already secured the license it's unlikely you'll get a better answer.
Also due to Covid, license negotiations and getting all the material together and authorized may take longer than usual.
