Various Unlockables
     When  you first start the game, you'll only be able to select the
Arcade  Mode.  Beating  it,  however, unlocks a few extra features and
modes.  You'll be able to unlock a third playable character, a gallery
with various cutscenes and art, level select, and a few mini-games.

Unlockable:                             How to Unlock:

Hikari Kujou/Shiny Luminous             Beat Arcade Mode

Gallery                                 Beat Arcade Mode

Level Select                            Beat Arcade Mode

Mini-Game Mode                          Beat Arcade Mode


Extra unlockable art and cutscenes
     Though  you'll  obtain much of the game's art gallery in a single
playthrough, you'll still be missing a few scenes and art. You'll have
to play through the game again with the third bonus character in order
to get them all.
