If this follows any tropes we know so far -
1. Rude will defeat the wolf (with or without the help of his harem friends)
2. a) Rude (and party) slay the wolf, gaining more recognition (probably unlikely, but this is honestly what I'm hoping for, just to subvert the trope)
2. b) The wolf will be tamed by Rude and will be subservient to him, becoming a valuable member of the party (more likely, and leads to step 3)
3. a) The wolf will become smaller, effectively becoming the "pet" of the party
3. b) The wolf will turn into a human, very likely a loli, and join the harem party
3. c) The wold will stay in large animal form but have human characteristics (talking etc.) maybe after getting purified? Church Saint is here, after all
3. d) Some combination of a) to c)
Did I forget anything so far? lol
