Uta no☆Prince-sama♪ Maji Love 2000%

Both deal with being in show business and working under a company that trains potential stars. Rivalry becomes more predominant from both show to prove who can come up on top. Has it's own comedic moments and a hint of romance amongst idols which is forbidden in the industry. It'll sure to entertain especially to a female audience! 

The same shoujo who has a lotta male admirers, the only difference were, one has the members of the harem competing for the shoujo's affection while the other doesn't.  

Kiniro no Corda and Uta no Prince-sama both involve with music, one girl with many guys in a group & go on a competition. Basely the exactly the same thing except Kiniro no Cora has a story with interments instead of singing like Uta no Prince-sama.  

both have to do with music, except that AKB0048 is all about just girls singing and fighting while Uta no Prince-sama Maji Love 2000% is abou guys singing songs a girl wrote. 

Reverse Harem with lots of bishounen guys. They can all sing and dance!! Same voice actors from STARISH, Quartet NIGHT, and HEAVENS are in Brothers Conflict.  

The character design and animation reminds me so much of Hetalia series. Similar personality too.  

Both animes are reverse harem, they give of a nice comedy feeling, and a little bit of romace. OHC focus's on a host club while UNPS focus's on their music. But if you like one or another you'll enjoy this.
