The development team hoped to include Phoenix Wright and Franziska von Karma from the Ace Attorney series, but, while the latter's use of a whip made her easy to incorporate, the team struggled to find appropriate attacks for Phoenix. Though they envisioned an attack that used his catch-phrase "Igiari!" ("Objection!" in English), with the letters themselves used to attack the opponent, they found that localization would have changed the four-character phrase (in kanji) to a ten-letter word, which would have unbalanced the game.
