"Breaking News: Three Pro Heroes Have Gone Missing! Last night, Pro heroes All Might, Endeavor and Aizawa went missing. All three heroes were last seen during the middle of their patrols, but neither one of the three returned. Other heroes and local police have looked over each heroes patrol route, but no evidence of the disappearances were found. As of now, patrols have been doubled to keep an eye out for anything related to the missing heroes." 

~3 Months Later~

"They're finally awake."

"The Doctor must have made sure everything took properly."

"Three heroes at once? That's something new."

Hushed voices whispered to each other as the three males were placed into their cells. Two of them were placed in one cell together while the other one was placed in a cell by himself. The other occupant of the cell was currently out. The voices whispered for a few more minutes before they went silent, all shocked when one of the new subjects started to sit up.

"F-Fuck...my head..."

His vision was blurry as he tried to register where he was. He ran a hand through his hair as his vision cleared...and then gasped as he finally saw his surroundings.

"What the...Where the hell am I!?"

The hushed voices returned, sounding nervous and slightly scared. "Shh...you can't be loud here. You'll get in trouble."

"Who's there?" The hero stood up, going to the bars of the cell he was in. He tried to use his quirk, but the second he tried an electric shock coursed through him, making him yell out in pain and fall to the floor.

"D-Damn it...!"

"K-Keep it down. My head is spinning." Came a gruff voice beside the flame hero.

"Huh?" Endeavor looked behind him and was shocked to see who had spoken. "Eraser? You're here too?"

The Erasure hero was sprawled out on a cot in the corner. To say he looked even more tired than usual was a bit of an understatement. Aizawa sat up, swaying a little bit as he slowly adjusted to being awake.

"Any idea where we are?"

"Not a damn clue. So far from what I can see, we're somewhere isolated...most likely...and locked in what appears to be jail cells. And...we're not alone."

Aizawa looked at the Flame hero and then looked out at the darkness surrounding them. He didn't see anything at first, but as he let his eyes peer into the shadows, he soon saw what was around. More cells like the one he was in...and more prisoners too. Though, something seemed a little off about the ones he could make out. 

"Hm..." With a breath, he got to his feet and stumbled to the bars for a better view. He saw that a long row of cells stretched as far as he could see, disappearing into the shadows. He then focused on the cells in front of him. It took him a bit before a gasp left him. 

"Endeavor. There's...children. The other cells...are full of children."

"What?" Endeavor looked at Aizawa like he was crazy and looked at the cells himself. His eyes widened in disbelief as he saw that what his companion said was true. In the cell across from him, he could make out the forms of at least three children. They seemed to range in ages between eight and twelve. As he looked down the cells, it was then that he could hear the sounds that filled the air. Whimpers and cries. All filled with sadness...and fear. 

"What the...What the hell is this place!?"
