April Fool's ficlets

I intend to publish a collection of omakes/drabbles/oneshots and the like on April 1st, AKA April Fool's day. I'll welcome prompts of all sorts, including crossovers, AUs, etc., and dust off some of the things people have told me they would like to see but couldn't fit in the main continuity.

So, send me all your ideas! Be they vanilla, e.g. coffeeshop, fantastic as vampires, weird as in some sort of time travel body switch ridiculousness, tell me, the more detailed the better. (Nothing explicit though, I can't write that sort of thing). Omakes that will be written include

- Shakespearean language lessons from Basil so the Varia can understand what Bel is actually saying and be able to talk to their little psychopath without needing a Basil-translator (prefaced by scenes of aforementioned translating happening with an increasingly displeased Basil).

-One exception being the firearms stuff he clearly has trouble with, and I can honestly see this Basil attending initially once, disappearing mid-class for the sake of his ears, and never returning.
Like, other times he might be arguing that yes he was there, no he didn't skip, they just weren't paying enough attention, but that class he actually is skipping and once any teachers get used to not being bale to keep track of him and start automatically marking him present he's golden until Finals. XD

-Ninth finding the Avengers on his desk someday.

-semi-canonical peeks into the future

-regarding Angry but competent Xanxus bringing up terrible memories of Ricardo's reign, Bloody Mist Basil goes: Is he going to start genociding his own people? Is he going to close borders and make every generation of kids fight each other to death? Is he going to destroy us? No? Then he's a perfectly decent don, as far as I'm concerned.

-If anyone wants to collaborate on some sort of whacky gambit pileup in which we have a more standard SI panicking because this isn't how it's supposed to go, I'd love to!

Crossovers too, and this is the list of fandoms I am capable of crossing into:

Anime/Manga:

Assassination Classroom

Black Butler (terribly)

Naruto

Rurouni Kenshin (the anime only)

Spirited Away (somehow?)

Books:

Harry Potter

PJO

Artemis Fowl (not quite that well)

the Tolkienverse (I'm still leveling up my nerdery)

Good Omens (Probably... I'm pretty sure that Adam and Basil meeting would just result in weirdness)

Dresden Files

Hunger Games

Movies:

MCU

Comics

Batman (Maybe? Does reading fanfic count as anything?)
