Odayaka Kizoku no Kyuuka no Susume.

Lizel opens his eyes in a city that looks familiar, but he is sure it is not his own city. Soon, he realised that he somehow reached another world and had no idea about it. Lizel has a calm nature, and instead of getting panicked, he decided to know more about this city. He then hired a skilled adventurer named Gil to guide and protect him until he found a way back home. He knew that he would have to go back, and for that, he decided to enjoy the vacation in the other world and enjoy his new life as an adventurer.
