 If you liked
Dimension W

 ...then you might like
Deca-Dence
|
You will encounter the exact relationship between the Man and the Girl. Especially the apathetic middle-aged man Kaburagi and Kyouma.
Battle and action rely on physical ability and the use of mechanical tools.
The Sci-Fi concept of the two is nearly similar (I think).
And you will recognize something about their World mystery (as the story progresses)
Both are set in the future timeline.
Extremely similar shows. There is a relationship with an older man who has a background shrouded in mystery but also experience and wisdom with a young female main character who is learning to cooperate with the man. They both take place in future settings and both have good character development. I really think if you like Dimension W then Deca-Dence is a must-watch and vice-versa. Once you've seen one and then watch the other you will instantly see the similarity.
