What can you do after the Story Mode in Yu-Gi-Oh Reverse of Arcadia?

Answer 1

After you finish the initial storyline, there are mini "side quests" that can be initiated by talking to or examining the appropriate person/object:

• Facility Chief - Examine the notice near Peko (Structure Duels) in New Domino City. You can now duel the Facility Chief who stands in front of the entrance to the Facility.
• Bolt's Challenge - Defeat Bolt Tanner in a Duel (next to Blister). Then, go to Jack Atlas' Duel Arena's waiting area and examine the heater in the upper-right hand corner to receive a card.
• Natsumi's Missing Daughter - Find Hana in the maze inside the first Duel Gang's hideout.
• Dark Signers Aura - Talk to Crow and head to the Old Enerdy area and talk to the purple mist to Duel all five Dark Signers. You must Duel each one consecutively. Life Points are not reset in between Duels (If you have more than 10,000 Life Points at the end of a Duel, you will start with 10,000 during the next Duel).You will receive a card as a reward if you beat all five. This side quest is needed to trigger "Torunka the Stylist".
• Signers Aura - Talk to MC and head into Jack Atlas' Duel Arena and talk to the purple mist to Duel all five Signers. You must Duel each one consecutively. Life Points are not reset in between Duels (If you have more than 10,000 Life Points at the end of a Duel, you will start with 10,000 during the next Duel).You will receive a card as a reward if you beat all five. This side quest is needed to trigger "Torunka the Stylist".
• Enforcers Aura - Talk to Kalin and head upstairs to the top floor balcony and talk to the purple mist to Duel all four Enforcers. You must Duel each one consecutively. Life Points are not reset in between Duels (If you have more than 10,000 Life Points at the end of a Duel, you will start with 10,000 during the next Duel). You will receive a card as a reward if you beat all four. This side quest is needed to trigger "Torunka the Stylist".
• Rossi's Wing SP - Talk to Rossi and search for Wing SP on Daedalus Bridge (incomplete one). He will then give you Colossal Fighter as a reward.
• Unlock Fun Key - Defeat Kyoto in a Duel and he will give you the Fun Key which is used for the Sector Security Headquarter's treasure maze.
• Corse's Tag Duel - Talk to Corse who will ask you to find a way for him to Duel Akiza. Then, change your Tag Partner to Akiza and talk to Corse again. This will initiate a Tag Duel between you and Akiza against Corse and Figaro. You will then receive a card as a reward after the Duel.
• Okita and Liquid's Dilemna - Talk to Okita or Liquid in the Arcadia Movement Headquarters. They will ask you to find them a home. Go to New Domino City and talk to Blister. He will allow them to stay in the extra room (originally inhabited by Akiza). Go back and talk to either Okita or Liquid and they will move into that room. They will give you Hyper Psychic Blaster and Hyper Psychic Blaster/Assault Mode as a reward.
• Ghost's Duel Runner - Talk to Trudge and engage in a race. If you catch Ghost, you will receive his Duel Runner.
• Torunka the Stylist - After you defeat each of the Auras, you can talk to Torunka. He will then proceed to reward you. He will also state that if you further beat him in a Duel, he can change you facial appearances. Keep in mind that you must beat him in additional Duels if you wish to change again.
• Chihiro's Star Chips - Collect Star Chips throughout the game to trade them to Chihiro for various rewards that are otherwise unobtainable within the game's parameters.
• Dexter's Card Dreams - Talk to Dexter (in the Underground Duel Arena). He will ask to see a specific card. If you have somehow obtained that card (via booster packs, password, Action Replay, etc.), you will automatically "show" him, and he will give you another card as a reward. Note that you can do this a limited number of times before he stops asking to see cards.
