Lmao I don't think he'll be saving too many girls from the mutated monsters though. A lot of em will get eaten or tentacle'd. I'm looking forward to the next chapter
And remember Momo was the one who almost got them killed/raped when she opened the window of the car in one of the earlier chapters. Tbh the most useful thing she could do for them is be bait
I think the sister might not be feeling well because she got blasted full of zombie cum at some point, just like Chiyo. I think we'll get some answers to one of the mysteries of this manga in the next chapter.
