I'm just a humble person on Wattpad that writes terrible one shots. I will also attempt to write any story or one shot if someone requests it. 
Fandoms:
Attack On Titan
Off
Undertale
One Piece
Voltron: Legendary Defender
My Hero Academia
Mob Psycho 100
Hetalia? (requested only)
Homestuck? (Requested only)
No Game No Life (ill try)
Mystic Messenger (??? I couldn't make it past like day four, unfortunately, but I'll do heavy research on it for a request.)

I may have forgotten one or two, so just send me a message and I'll let you know if I am familiar with the fandom! Just remember that it may take a while for your request, since my mind isn't filled with ideas. Ideal requests would be ones that gave more details (situation, fluff or others, etc). 

One more thing. No mature content. I'd prefer not to resort to that side of my brain, so I will politely ask you to find another who is willing to fulfill your request. 

     I'm also willing to edit a story if any of you authors out there don't feel up to it! Just private message me!

Thank you and have a great day!
