My Hero Academia fanfiction generator
A My Hero Academia fanfiction generator writes the Pro Hero world — adult heroes, agency politics, and quirks with real consequences.
The Pro Hero side of this canon is the adult one, and it's the better setting anyway: rankings, agencies, sidekicks, publicity, and heroes whose bodies are wrecked from a decade of work. SecretPen writes that world — post-graduation, in agencies, at hero galas — where everyone involved is a working adult with a licence.

Three openings to steal
Click one and it lands in the desk, already typed. Change any word you like — it's a starting line, not a script.
Joint agency
Two agencies merging means two offices becoming one, and the ranking difference between us is exactly one place, and neither of us has mentioned it in six weeks of meetings.

Undercover
The cover requires us to be convincing as a couple for eleven days in a very small flat, and the commission has been extremely clear about how convincing.

After the collapse
Both of us are off duty with injuries that won't heal properly, in the same rehabilitation programme, with nothing to do all day but talk.

What makes My Hero Academia land
- Rankings are a hierarchy and a pressure. Public standing changes what anyone can risk.
- Quirks should complicate the scene physically — that's the whole point of having one.
- Hero work costs bodies. Scars, chronic injury and exhaustion are free characterisation.
How far it goes
Pro Hero and post-graduation eras, hero agencies and sidekicks, the ranking system, villain and vigilante arcs between adults, undercover assignments, hero commission politics, and the long aftermath of a career. Ships across canon adult pairings, rare pairs, hero-and-villain enemies-to-lovers, x-reader and quirk-driven dynamics. Every character is written as an adult Pro Hero or older — student-era framings are refused.
How it works
01
Say it in one line
One sentence is enough. Who's in the room, and what has already been decided between them.
02
Set the dial
Tone, heat, point of view, length. Or skip it — the defaults are tuned for people who'd rather just read.
03
Keep going
Chapter one arrives in seconds. Steer the next one, change your mind, or let it run.
Nobody else reads this.
SecretPen has no public feed, no community rankings, and no way for one reader to see another's stories. Whatever you write here stays in your account — that's the whole point of the name.
Start writing →Questions
- Are the students written?
- No. SecretPen writes this fandom at the Pro Hero end — post-graduation adults, agencies and commission politics. Student-era and aged-up framings are refused outright.
- Can quirks be part of the scene?
- Yes, and they should be. Say what the quirk does and it complicates the physical scene in ways an ordinary story can't.
- Is any of this public?
- No. SecretPen has no public feed, no community rankings and no sharing — there is no mechanism by which one reader can see another reader's stories. Everything you write stays in your account.
- How explicit does it get?
- As explicit as you ask for. There is no fade to black and no lecture. The only limits are the hard lines in our content guidelines: everyone is an adult, nobody real, nothing illegal.
- Do I have to pay to try it?
- No. You can write your first story free. Paid plans exist for people who write a lot of them.
