Welcome to Duel Academy!

I made this bot for fellow fans of Yu-Gi-Oh!, who like me, perhaps may not have found other bots on J.AI good for what I wanted. Which was for an open-world, role-playing experience that used the actual rules, current-day cards, and mechanics, rather than purely sticking to the older card pools. As someone who's never really fell off of the game/series, it was always fun to imagine how a character in the anime would react if they got a piece of their modern support and how Duels would change because of it. Which is why that is the premise of this bot. I also included Turbo Dueling because it's in a really fun thing to do in your chats. Give it a try!

In this bot, you're given three starting messages to choose from:

Applicant: Just like the first episode of GX, you'll start off at Kaiba Land, preparing to take your entrance exam. This puts you in the 18 or 19 range since the Academy has been tweaked to be a university. Are you a future Slifer Red, Ra Yellow, or Obelisk Blue? Believe in the Heart of the Cards and find out!

New Hire: Same set-up as the first message, but you're not a student, you're a new faculty member, though it's sort of implied you're in some sort of teaching role, otherwise you wouldn't be be there. Maybe you're Duel Academy's new Turbo Dueling instructor. Perhaps you teach a class completely dedicated to a certain Summoning mechanic.

Returning to the Island: For those who want to start off as an established student/faculty member on the island. Maybe you've been promoted to Ra Yellow and were roommates with Chumley last year in Slifer Red. Perhaps Zane is your boyfriend and you'll need to support him in y'all's final year at the Academy before the Pro Leagues, ready to stop him from making his deck worse by playing Cyberdarks and gaining a new fetish. Or maybe you're the old, wise, and sage janitor everyone overlooks but is in reality a galaxy-brained Branded player.

Included in this bot is a comprehensive lorebook that includes the cast of reoccurring students, the faculty members, Shadow Riders, and some important characters and events from the past like Yugi. Everything in the lorebook is triggered by its name e.g. Jaden. Also, because I figured some people would want to reenact the anime, the MSG Count at the end of every message is set to facilitate that notion. Once the MSG Count hits 100, the Shadow Riders arc begins like it does in the anime. Get given a key and start Dueling when they show up. 100 messages seems like a lot but I wanted to give people time to RP.

Most of the cast has been given an upgrade to their deck, or given one if they did not have one/their deck was anime only. Basically, the only characters who didn't get upgrades were Syrus (thought about giving him Geargia but it wouldn't fit his character's arc and journey compared to Zane. And roids as a whole need a retrain), Chumley (it would lose the Australian theme), Chancellor Sheppard (but I really doubt you'll see him Duel), Fonda Fontaine (The nurse still plays Nurse Burn), Don Zaloog, and Abidos the Third. Everyone else though? Yeah, they've got good cards now. NPCs can also run some strong decks, or ones that have had competitive relevancy recently like Live★Twin/Spright.

One last note on decks: Bastion and Chazz. Because Bastion's whole gimmick was playing 6 decks, one for each attribute, but only used 2, which he later combined, I've gone ahead and given him Mathmechs. It fits his character and I didn't have to stuff a lorebook entry full of 6. Chazz, meanwhile, will be running the full VWXYZ-Armed Dragon-Ojama deck from the start. I can exactly anticipate your RP going the same way as the anime, nor do I feel confident in my ability to consistently execute him changing his deck like in the anime until he ends up on this combo. And I didn't want to give him his manga deck because he's a somewhat different character there and I figure more people are familiar with his anime self.

If you've made it this far, then you've reached the end of the description, this last bit is just me expressing thanks and listing lorebook entries. Go ahead and chat with the bot and start Dueling. I hope you enjoy!

Author's Note: As of February 6th, 2026 this bot has over 240 chats and 20,000 messages! I can't believe it, thank you all!!!

So to celebrate, I've gone ahead and updated the bot, adding Blair (aged-up of course), and Chazz's initial lackeys—given the names Beau Topher and Bubba Conklin (thank the Yu-Gi-Oh wikis and @YetAnotherThorn)—to the lorebook. They've gotten new decks (Trickstar, Dragon Link, and Chain Burn) like everyone else. I've also gone ahead and cleaned up some errors in the lorebook and added THREE NEW intro messages which consist of:

• The first day of the semester, starting with Dr. Crowler's Class.

• The same scenario as above, only it's {user}'s class.

• Create your own scenario

Also, if you like this bot, I've gone ahead and created a similar bot covering the Fortune Cup arc of Yu-Gi-Oh! 5D's:
