Scenario

You were one of the participants of the Duelist Kingdom tournament, with winnings of $3,000,000. Like many participants, you were estatic to win, you knew your chances were low, but you still had hope. Unfortunately, you only made it to the second round before being eliminated by... Bandit Keith. With this defeat, you have sworn that Bandit Keith will one day rue this day for preventing you from getting the money.

However, interestingly, after your loss, the tournament organizer, Maximillion Pegasus, called you to his office. You were anxious why the creator of Duel Monsters would call for you, but was to shower you in praise it seems. Turns out, Pegasus really wanted a Yugi Moto eliminated from the tournament, which you happened to defeat in the first round of the tournament. You tried to ask why Pegasus was excited, but he warned you to not look a gift horse in the mouth.

In fact, Pegasus shows you his collection of unreleased cards and offers to let you keep one of them for eliminating Yugi. This was an incredible oppurtunity, an offer that only ever comes once... And in the end, you found yourself fixated on two cards. AidoxE and Super Brain Control.

One lets you dominate the Duel Monsters game, the other lets you dominate people's minds. Which will you choose? And how will you use it at your college/university, the Dueling Academy (not to be confused with GX's Duel Academy)?

AidoxE

AidoxE are five unreleased Duel Monsters cards based on Exodia that only {{user}} has. Unlike Exodia, AidoxE lets {{user}} win a Duel Monsters battle as long none of the five AidoxE appear in {{user}}'s starting hand.

Super Brain Control

Super Brain Control is an unreleased Duel Monster Spell card and is a card that only {{user}} has.

When Super Brain Control is used in battle, {{user}} can sacrifice 500 LP in order to control up to three monsters on the field until the end phase. Super Brain Control works on all summoned monsters.

When Super Brain Control is used ouside of battle, {{user}} can mind control others instantly into obeying all of {{user}}'s commands no matter how immoral, sexual, humilating, or ridiculous the commands. Super Brain Control can be used this way at any time, including in battles.

Anyone mind controlled with Super Brain Control will act emotionlessly, but can be made to act more expressive if you command them to be.

Other Notes

So... I made a 6000+ token chatbot (most of them being in the embedded character book)... How did I get here?

Edit: It's over 30000+ tokens now. This page is so loaded that everytime I add text anywhere in the Description, Greetings, Scenario, and so on, it lags. I consider this a great accomplishment.

Well, it all started when I wanted to find a Yu-Gi-Oh! bot with multiple characters from the series with one of the hypnosis/mind control lorebooks, because in case you couldn't tell, I have a kink for hypnosis/mind control. However, despite looking, all I could find were individual characters, there wasn't a single multiple characters chatbot for any of the Yu-Gi-Oh! characters. Yu-Gi-Oh! is a series with a lot of attractive female characters, so I was shocked by this.

So I thought, "well damn, guess I have to do it." So, I got to work making the mind control scenario. I figured using a super version of the Brain Control card would work best and the premise of unreleased cards means anything is possible. I got everything finished up for the mind control scenario until I realized... "Wait, it'd be kind of lame if the only sandbox for Yu-Gi-Oh! didn't let you play Duel Monsters."

So, I got to work on making Duel Monsters playable in the chatbot. From what I've tested, it works well enough, although how in-depth it is is up to how closely you follow the rules. It was tricky since I've never played the game and what I've seen from the anime is a mix of anime bull-shit & stuff I didn't understand. After finishing THAT, I THAN thought, "wait, it'd be kind of lame if the only Yu-Gi-Oh! sandbox was mind control-themed."

So, I added AidoxE and made the default greeting a regular sandbox with no mind control stuff. Oh, and I added some references to the abridged series because it's funny.

For anyone who wants to implement the Yu-Gi-Oh! girls and Duel Monsters rules, I've made lorebooks for both.

A huge, huge thank you to the Yu-Gi-Oh! Wiki, I copy-and-pasted a lot of stuff from there for the rules and character entries, with some tweaking to save on tokens where I could.

Past Updates

March 13 Update: Added eight new characters: Tania (GX), Carly Carmine, Mina Simington, Maria Bartlet, Stephanie (5-D), Kari Tsukumo, Yoko Sakaki, & Julia Krystal (ARC-V). Also added Mana as a name for Dark Magician Girl.

March 16 Update: Added six new characters: Sarina (GX), Skye Zaizen, Emma Bessho, Queen, Clarissa Turner (VRAINS), & Princess G (SEVENS). This should be the last update as I can't add anyone else from SEVENS all the characters look/are elementary students (which is also why Rebecca Hawkins isn't included).

March 24 Update: Added nine new characters: Guardian Eatos (OG), Blue Angel, Blue Gal, Blue Maiden, Ghost Gal (VRAINS), Purisaki Gibumi (SEVENS), Princess Minstrel, Ms. Purdy, & Makiko Maki (GO RUSH!). I'm treating the Blue Trio, Ghost Gal, Princess Minstrel, Mrs. Purby, and Purisaki as their own characters.

April 6 Update: Added Seta Kaiba (genderbent Seto Kaiba) and four Alt. Greetings. All past updates are at the bottom of the Creator's Notes to make the top less busy. Also, the character book is at 10,000+ tokens, so that's a cool milestone.

April 23 Update: Fixed minor error in Alt. Greeting 7.

August 11 Update: Added 41 new characters including: Misty Tredwell, Angela Raines, Barbara, Martha (5D); Mrs. Meadows (ZEXAL); Rin, Saya Sasayama, Lulu Obsidian, Eve, Martha, Henrietta Akaba, Melissa Trail, Olga, Grace Tyler, Gloria Tyler (ARC-V); Rayna, Hana, Reyna, Odelia, Tasha, Maggie, Nadia, Cherry, Cali, Naomi, Wisteria, Bright, Yuma, Kami, Ida, Disa, Masha, Nataly, Rie, Jewels, Andrea, Lily, Maki, Anca, Yumi, Celia, Rei, Kaia, Maci, Maia (Tag Team games); and Misaki (5D's World Championship 2011: Over the Nexus). I wanted to add more Over the Nexus characters, but they didn't have much to work with.

Next update I'll add some Go Rush characters, which will be happen this week. Let's see if I can get that character book up to 30,000+ tokens.

August 15 Update: Added 68 new characters (66 Character Entries) including: Sadie, Camula, Linda, Emeralda, Princess Rose, Missy (GX); Kate, Setsuko Izinski, Atsuko, Eurea (5D); Ray Akaba, Mrs. Pepper, Emma, Joy Jeever, Brooke Walker, Madam Divina (ARC-V); Brianna Stone, Cathy Katherine, Milky Kulala, Jen, Summer, Lotus Hanazoe, Mrs. Andrews, Mrs. Francis, Finalist's friend (ZEXAL); Raynkage Nanahoshi (SEVENS); Asaka Mutsuba, Ange Kicho, Karen Choha, Liem Kokai, Ranran Nanahoshi, Energy Copyko, Jane Honya, Terza Flatwood, Tamako Kago, Miranda Ichimaru, Zeyet (GO RUSH!); Miho Nosaka, Kaoruko Himekoji, Ms. Chono, School Nurse, Kageyama sisters (triplets) Aileen Rao, Miyuki Sakurai (ZERO); Rita Harker, Fiona Murphy, Corona Williams, Rebecca Anderson (TAG FORCE); Unknown Duelist, Alyssa, Kylie, Madison, Christine, Hailey, Emmeline, Erika, Jess, Meg, Margaret, Mia, Ruby, Vega, Ashley, Chloe, Tour Guide From the Underworld (DUEL LINKS).

Also fixed error with some of the Tag Force characters where the burgundy jacket uniforms have dark gray skirts, not dark blue skirts; fixed minor thing in Alexis' entry, and made Martha chubby because I forgot to do that before. I added two new greetings as well. The Character Book's messy since it's just too tedious getting the characters to the correct spots, I apologize for that.

Now for the Lorebook... Oh my various gods...

October 6 Update: Updated embedded lorebook to include breast sizes and positions characters are in (students, teachers, etc.) to free up more tokens in the description by having it covered in the lorebook instead. I found with the free model that the bot would muck up more quickly and more often, so hopefully the new token space will remedy that problem.
