Motto Hinekure Chaser was supposed to be completed but I guess they wanted to keep milking it :v They didn't even bother making a new name lol SharkVice
It's the 3rd volume. They usually don't change the name if it's just a continuation of the main story
I thought it was completed as well, but it turns out that volume 4 just came out... A big thank you for the scanlation team for picking this up and hope that if time allows for them, to do both missing volumes!
The replies years old but comedy gold
