Our Party Nearly Wiped and Then Everything Went Downhill, Vol. 1 — Ameria

Walker, a man reincarnated as an adventurer, is suddenly attacked in a dungeon by a high—level monster and realizes he’s in the dark fantasy world of a manga he read in his previous life. Not only that, but he isn’t the protagonist…he’s an ill—fated side character, meant to die alongside his party to establish the setting’s grim tone! Walker fights tooth and nail for his friends, and although he loses a leg and an eye in the process, he manages to avert everyone's terrible fates. But as he adjusts to a new life with an injured body, his female comrades begin to act strangely toward him!
