So i recently contacted Dark horse comics inquiring about a physical manga release, here’s what they said.
"At this time, we do not have plans to publish Nanbaka. However, this can change in the future, so please check back on our website for up to date news"
So what it seems is if there is enough interest they could possibly release nanbaka so if you want nanbaka physically released outside of japan or if you just want to support Sho futamata shoot darkhorse an email at https://www.darkhorse.com/Help/Contact/
Please pass this along
also if you like to share darkhorses response feel free
