Divine gate is a Japanese smart-phone game for iOS and Android. The characters appear as a boss in-game. You fight them and are then shown a screen of them.

 

   

                                           

 

 

 

                          

             

 

Gameplay of the game and how the cameos work can be seen below.

 

In this video, the boss is a version of Alice from Alice in Wonderland. Battle: 5:21  Character screen: 5:51

The game is so open to cameos, that characters from a few different animes, such as Toaru kagaku no railgun and Date A Live, have also starred in it.

I find it very interesting how Japanese created a full background story for the Vocaloids.

I even thought Vocaloid was a manga, at some point.

Thats amazing! I wish i could play it....
