Non-exhaustive list of WIPs I have written some portion of:
Post-DSoD thing where Noa returns with Kaiba, who reluctantly takes him in; Noa has to learn to live as a fleshperson again, and it is not easy or fun (maybe just Kaibro-centric gen, but was leaning toward including established KJ; did not get far enough)
So many scattered parts that were meant to someday constitute a continuation of University AU
Sock wars (;____; what I have written is still so good... I HAVE to finish it someday)
Clandestine supernatural critter AU where knowledgeable werewolf Jounouchi rescues a newly turned and utterly clueless vampire Kaiba; Jounouchi feels grudgingly obligated to help Kaiba navigate this new world he didn't ask to be a part of (I liked what little I wrote of this one SO much that I was like... I don't even know if I want this to be fanfic... I might want to steal some of these turns of phrases for my original projects dlkfjdslkfs)
Otogi, Bakura, and Shizuka hanging out and speculating on whether or not Honda is interested in men... might have been more gen but I cannot remember how I wanted to end (background)
Flower viewing meetup between Kaiba, Jounouchi, and Otogi, who have recently started going out (petship)
Otogi is jokingly trying to get Kaiba on board for developing a Dungeon Dice Monsters app, but Mokuba is like "hey write up a business proposal" (I don't remember if this was potentially going to be petship but it was definitely an already-established... mastership?? that's the name?? god)
Followup to Empty Tombs and Vacant Spaces where Bakura and Malik have a communication breakdown, and Malik takes off; Isis and Rishid visit looking for Malik, who also took off from home without telling them anything (angst)
Followup to Secrets with Teeth (battle)
Haga and Ryuuzaki attempt to get revenge on Yuugi and co by picking out the "weak link" in their friend group and trying to poach them, but the closest thing they can find is Bakura... and the fact that he's so cute keeps distracting them; Bakura, for his part, goes along with it and humors them because he finds it endearing (Ryuuzaki/Haga/Bakura, which doesn't have a name, to my knowledge... puts my face in my hands... I'm not doing this again)
Bakura and Shizuka run into each other while trying to escape their fangirls and fanboys, respectively, realize they have some things in common, and start playing tabletop RPGs together (someday... someday you WILL all understand my Bakura+Shizuka friendship agenda... you will all receive my vision...)
Bakura writing letters to Yami Bakura, who is now gone, trying to contend with their lack of a relationship (under the basis that Yami Bakura rarely or even never communicated with Bakura during their time sharing a body)
