Kyokou Eiyuu GinGaia

This is a story about someday becoming a dad. Hideo Kanbara lived an ordinary life with his wife and kids. But one day, he got thrown into a post-apocalyptic world and came face-to-face with a giant monster. As Hideo ran for his life, a mysterious robot appeared right in front of him... Sounds like your typical hero story, right? But there's no hero's journey here, there's no place for dreams or hope in this story...
