The Unwanted Undead Adventurer (Manga): Volume 1

Its been ten years since Rentt Faina, a luckless Bronze-class adventurer, set his eyes on becoming Mithril-class. Unfortunately, he finds himself helpless when confronted by a legendary dragon in the Water Moon Dungeon...and is summarily eaten. But Rentt has miraculously reawakened...as a skeleton?! Making his way back to civilization is going to be a challenge when he can barely walk, let alone hold a sword. And the good people of Maalt wont take kindly to a monster in their midst. Can some magic techniques and a chance encounter provide Rentts salvation?
