Phantom

Rummaging through some boxes, Phantom finds something she's been looking for, proudly presenting to the protagonist a game cartridge labeled "MIDNIGHT PHANTOM RUNNER." A simulator program she commissioned to train budding phantom thieves. Phantom herself beams as she notes the unique nature of this simulator, having instructed the creator to fashion a high-difficulty course for the Thieves of Justice. Phantom intends to have Yukiko, Teddie, and Aigis undergo this simulator to train so they can help catch the rogue phantom thieves causing a disturbance in the Ark. She also pulls out a manual and suggests the protagonist also use the trainer, so he can help teach the others. Though it appears Phantom personally drafted this manual, if the sheer number of typos on the cover is any indication.
