Base on the afterword, it is really only adapted till this point. Either they'll get another or not is a gamble, 'cause author's permit is the most crucial thing, even if mag publisher have a plan for next adaptation, if the author doesn't give their permit for whatever reason, then it is a no-go, also list of tittles waiting to get adapted and printing cost is still pretty high it seems (I suspect this is also one of many reason chapter getting chopped into smaller part)
All accessories in this story are EXTREMELY OP. You don't even need much power at all anymore. Just equip some high ranking stuff, become insanely powerful with the power to destroy a city, and you're good!
