Summary
Lucithia Malfoy is sent to her first year of Hogwarts, despite protests to either continue her schooling at Mahoutokoro or to attend Durmstrang. Her mother doesn't want her daughter to stray too far for her first 'proper' year of wizard schooling.
Little does she know the chaos that will ensue, now that she must work with some really annoying Gryffindor kid who keeps breaking into their common rooms, why does everyone fall for it? And why are the passwords so easy to guess? Pureblood cannot be a secure password for Slytherins...right?

Summary
Catapedamania, 'obsession with jumping from high places', yet again another fic with a random word as the title.
Kazemi, like many others, has lived another life. And now, she's stuck in a pre-fall Uzushio, waiting for the other shoe to drop. Seals are weird, but she took computer science and maths, so she can figure this out probably. At least she has a million different colors of ink.[Updates Resume August 2025]

Summary
A pair of twins are born and both regain their memories of their past lives. While one was a martial arts dude and engineer or something, the other was a ballerina and model. Both have read Tokyo Revengers, and neither is happy to realize that's where they ended up, because for the love of all that is good and pure they do not want to get involved in gangs. But also, they have atrocious luck (The Male Twin POV, female is elsewhere in the abyss or maybe in my works depending on how motivated I am to write.)

Summary
Oh whoopee I died again.
I've gone by many names; Thais, Kimberly, Ben, Jerry... comes with the territory of living over and over again. I swear, I could've gotten into the isle of B half a dozen times by now but instead I'm just back here on Earth again.
At least I've never been a demigod. Being able to see through the mist is bad enough, I'd rather not get hunted. At least I've got my trusty old staff for protection.

Summary
"HEY! Old man, you're going to catch a cold."
A kid with a cute frog umbrella glares without malice at the soaking Kakashi sat in front of the memorial stone.
"Go home."
"No way, I dont need a senior citizen's death on my conscience. Cookie? Cookies make me happy."
"What-No I dont-"
"Eat the cookie," the child insisted, forcing his umbrella into Kakashi's hand.And thus began the saga of Baymax... I mean Nagi, Kakashi's personal healthcare consultant.

Summary
[Hiatus until Aug 2025]
Wendy Nakabe (nee Davis) is living her best life in the my hero academia universe. She'd dropped the series back in season 5 and barely kept track of occasional big things that happened in the show but had overall lost interest. Then she was born into a world of quirks, went to university, and fell in love without ever hearing the name 'All Might'.
She'd assumed she was decades away from canon.
She'd miscalculated.And she'd kind of kidnapped a kid.

Holy motherforking shirtballs I'm in here by OnyxAlchemyst
Fandoms: Hazbin Hotel (Cartoon), Helluva Boss (Web Series), The Good Place (TV)
29 Jul 2024

Summary
Imagine VivziePop's hell but they're forced to abide by the rules of the good place (i.e. no swearing, etc) because some random reincarnate-turned-seraphim from our world thought it'd be funny to censor everything. She ends up befriending Alastor through shared entertainment via Charlie's struggles, eats souls of sinners that annoy her from time to time. Generally enjoys smiting and the such. Wishes she wasn't in this world. Kind of adopts Sir Pentious because I think he needs some love. Biblically accurate angels, because they are interesting. This is basically the 'clean-er' version of Hazbin, if you shot the plot and dragged it out back to die and replaced it with something with the same start and a very different end. The plot is dead, I killed it.
TLDR; SI-OC angel decides to help Charlie for her own amusement, much to everyone's horror.

Summary
Wilhelmina (thank you very much for that one mum) was a somewhat disillusioned member of the 12th legion fulminata and is more than ready to say sono pazzi questi Romani and run when the plot strikes again. Unfortunately the fact that she only regained her memories of Blood of Olympus a day before the war began meant she had very few options.
So she chose the stupid one.She never said she wasn’t one of the crazy Romans as well.
