Summary: It's a story about a group of boys with a dream of becoming idols and their road to reach that dream. The path they chose will be filled with hardships and they will have to overcome them, if they want to reach their goal. Basically, it will be just like idolmaster, but rather than having all girl groups it will be all male groups. More importantly, it's actually somewhat like a spin-off of Idolmaster since one of the boy groups appeared in the original idolmaster anime. Since that original was about the girls we didn't get to see what happens to them... Even if this anime is standalone, I would suggest starting from original idolmaster and then moving to this one.
