Okay, I didn't expect they just needed to walk out of that particular patch of forest to reach the sea. The earlier chapters gave an impression it's a longer trip. Technically any random humans could have ended the undead ogre just by fleeing in the direction of the sea. The ogre corpse would have chased after them, easily ending up within sight of the sea, and self-terminated.
Considering the sheer vast amount of absolute garbage being produced by Japan on a daily basis, I still find it weird that "mid content" can't survive for at least 50 chapters.Well that what you get for being mid in a hyper competitive world...Sad
