Reading this after watching the first 4 episodes of the anime is wild. Haven't read past the 1st chapter yet but these are my thoughts. The anime did a better job at showing the summoning event, and giving a better/more believable justification for the goddess disposing of him. That being said...
Where can I find that? When I go to Viz via the link on the IAS page it just shows me Vol. 4 and the pre-order for Vol. 5? Same thing if I go to Viz and search for it.
