Mahou Shoujo Lyrical Nanoha A's Portable: The Battle of Aces

These remnants take form of twisted, dark copies of real people called "dark fragments" (闇の欠片 yami no kakera). In addition to Nanoha, Fate, and Hayate's own dark copies, they soon have to face the three much more powerful and dangerous clones of themselves known as "Material", as well. Every playable character must face and defeat the clones of their own friends to advance their storylines. All of the playable characters except the Materials have their own different story route in the game. Every route has the same basic structure: the player must first pass a training session, then defeat the dark clones of two of their best friends, defeat one Material boss, defeat the clones of two more freinds, then lastly defeat a Material boss version of themselves.
