Tsuki ga Michibiku Isekai Douchuu

Misumi Makoto was just a normal high-school student until the day he was summoned to another world because of an agreement his parents had made with a goddess. Except when he meets the only goddess in the world he's sent to, she insults him by calling him "extremely unattractive" and makes an arbitrary decision to banish him to a deserted wilderness. Makoto searches the desolate land to find other humans, but for some reason only finds creatures that are all nonhuman. Even the two pretty women who decide to follow him on his journey used to be a dragon and a giant spider. Along with two extremely eccentric characters (but really reliable in battles), so begins Makoto's unlucky adventure in the new world! A fantasy about a teenage boy who keeps getting hit by one problem after another!
