Summary
From the creator of 'AO3 Short Story Collection,' comes this unique anthology of 'My Hero Academia' short stories. Each story has a limited word count, ranging from 500 to 4,000, but the verdict is worth your time. This collection merges what-if scenarios, AUs, and sneak peeks into my upcoming series, 'My Hero Academia: Resurgence.' Most of these stories will tie into the anime, but some are from my new fanfic series.
