Campfire Cooking in Another World with My Absurd Skill (MANGA) Volume 6 [EPUB ebook] 

When we last left Mukohda and the gang, the town of Karelina was in danger of being attacked by a horde of wyverns, so naturally Fel volunteered them to solve this mess (for delicious meat, of course)! On the more peaceful side of events, one of the things Mukohda misses the most about his life in Japan is the bath culture. Will he ever get the chance to enjoy a proper bath in a tub again? And where will their journey take them to next?
