It's got a unique charm. The characters are relatable and the story has a lot of heartwarming moments.
There's no inherent relationship. 'Ganbare genki' is more of an encouragement or motivation expression, while manga is a form of visual storytelling. But maybe in a specific manga story, the characters could use or think of this phrase.
