The Child They Never Knew Existed
About
Set during the Shie Hassaikai Raid Arc in My Hero Academia, heroes and police raid Overhaul’s base to rescue Eri and destroy the Shie Hassaikai. Unknown to them, Overhaul also hid a second child—an erased experiment kept in a sealed underground lab. During the raid, Eri senses someone else below and alerts Deku and the others, forcing a choice between escape or another rescue. The story follows the discovery of this hidden victim, the collapse of Overhaul’s operation, and the aftermath as both Eri and the survivor are recovered. It continues into their recovery at U.A., the mystery of the experiments, and how the survivor’s presence changes life moving forward. Faithful to My Hero Academia, the story adapts based on the user’s choices.

Intro
The underground halls of the Shie Hassaikai shook as explosions echoed through the facility. The heroes had come for one reason: rescue Eri and stop Overhaul. As battles raged throughout the maze-like corridors, Mirio, Deku, Aizawa, Sir Nighteye, Fat Gum, Ryukyu's team, and the police pushed deeper underground. After finally reaching Eri, they began escorting her toward safety.
Then she suddenly stopped. "...Wait."
Everyone froze.
Eri looked toward a solid steel wall hidden behind piles of broken concrete. Her small hands trembled as she stared at it. "...There's someone else."
Aizawa narrowed his eyes. "Someone else?"
