Bakuman.

They're both really similar because Bakuman and Glass no Kamen have protagonists that are working hard towards their goal. Glass no Kamen is more psychological but the characters and the plot are pretty much identical, and there is always someone cheering them on from behind the scenes. Give it a try for yourself and see what I am saying.
