" five, what did you do? " " um, i changed the timeline? " " five! " in which the hargreeves go back a bit farther than intended, and it seems that five had screwed up somewhere because grace is human and reginald is a good father. [ the umbrella academy post season 1 ] [ part one of the time travellers series ]

"You will both be undertaking long term stealth missions elsewhere, but you won't be operating together for the most part. Dazai-kun, you've heard of UA high school right?" "Of course I have, it's like the most popular hero school in Japan or something. And now you're going to tell me I have to live my dreams and become a hero." Dazai jokes. The older man makes no sound, and Dazai turns to look at him. "Wait. You're serious?" Mori sighs, "Dazai-kun, you will be infiltrating UA high school and posing as a student there. You've already got experience in stealth training, but it will be a shame to let such a valuable executive go.." ------------- Dazai and Chuuya are sent on missions to infiltrate opposite sides of two parties that Mori has deemed a threat to the mafia, and to simply gather information from both sides. Is there more to this assignment than what they were informed of?

Utterly confused, the four of them realize that not only are they in an entirely different world, they have also regressed back to when they were all sixteen. I mean really, what's the big deal in that? Except not knowing how to return, struggling to cope up with an unknown dimension and some very confusing feelings that is.

WARNING: contains spoilers for those who don't read the Demon Slayer Manga Right after the battle of Upper Moon 1, and right in the middle of a battle with Kibutsuji Muzan, a bright light comes out of nowhere and they all black out. Right after the villains attack at the USJ, these strange people come out of nowhere Now the demon hunters and heroes band together to battle against the Upper Demon Moons and the League of Villains (In this, Muichiro, Shinobu, Genya, Rengoku and Oyokata have been brought back to life! How will everyone react to their resurrection? Swear warning!!!) This is my first fanfic so I'm sorry about any spelling errors!! (Characters of My Hero Academia and Demon Slayer do not belong to me)

An Umbrella Academy and Marvel Cinematic Unviserse Crossover What if the Avengers met the Umbrella Academy, specifically Five Hargreeves? Who would clash and who would become best friends? Read on to find out. This is an AU Please Note: I do NOT own any of these characters, they belong to Marvel and Dark Horse Comics. Except characters that I create. Warning: There will be a few curse words, but they will be partially replaced with asterisks.

When Five did his calculation he had no idea what he was doing. Or: how the Hargreeves Siblings meet the Avengers (Probably going to add in relationships such as Loki and Klause but if anyone has any suggestions let me know)

A Marvel x Bungou Stray Dogs crossover Inspired by little-coffin's story Idiosyncrasy Go check it out! It's the best Bsd crossover I've seen! The Avengers have to take down an enemy coming from overseas, the Port Mafia. What will happen when they capture a boy wrapped in tight bandages whom they know nothing about? Read to find out!

Saiki enters the prestigious UA High school for heroes. Will his life be as disastrous as it was in his previous world or will it be as peaceful as he normally wanted? (complete)

(Not gonna tag this one at all because it's majorly made for people that were interested by my community post) Just your average Double Black UA infiltration, right? Wrong! Somehow Technoblade ended up in this confusing crossover as well. How will two young mafiosos and an ancient warrior who's blown up a nation twice fare when trying to blend in with a bunch of morally white fifteen year olds, welp find out. Will Soukoku be able to figure out who the weird pink guy really is? He claims to be from Yokohama, but they've never seen him in their beloved city, how suspicious. Will Technoblade make it through the year without accidentally murdering someone? Who knows, if only the two kids from the Port Mafia would stop investigating him. (This might sound extremely light-hearted and goofy, but I've never written something actually light-hearted in my life, hence the mature tag. I'm not too sure where I'll take this story, but expect a lot of Techno murdering people, mostly on "accident" and Soukoku doing mafia business while traumatising their classmates. Not too sure if the gore I tend to write is graphic so be mindful of that when reading.) (Also please don't come after me for my grammar and or pacing, I don't natively speak English and I haven't written in pretty much a year, my writing will most likely get smoother and better as the story progresses so please give me some time :'D)
