If you told Aizawa five years ago that he was going to willingly lead a zombie to the bunker, he would've laughed at you before promptly shooting you in the foot. If you told him it would be a zombie holding an alive four-year-old, he would've shot you twice. But that was his life now, apparently.

Izuku was settled in Kacchan's arms, his own tiny ones wrapped around the blond's neck. His legs wrapped around the zombie's waist in kind. Kacchan had one arm under his butt, the other arm wrapped around the middle of his back, the hand buried in his green hair.

The zombie walked a few feet behind Aizawa; he was even more tense than before. Aizawa noticed that Izuku was humming quietly-loud enough for the zombie to hear anyway. Those high-pitched, gentle sounds seem to be the only thing that was stopping the zombie from attacking, so Aizawa let it be.

He swallowed harshly at the sight of the entrance to the bunker peeked over the horizon. He let out a sigh as forty men were standing around the area, all guns pointing at the zombie. Aizawa let out a growl-couldn't they see that there was also a child with them?!

"Put your weapons down! We have a kid here!"

Nemuri (aka Midnight) and Hizashi lowered their weapons immediately at the knowledge of a child, but the others weren't so accommodating.

"Aizawa, that is a zombie that you're bringing in!"

"He's not even tied!"

"I bet that kid is going to turn into one of them any second!"

A soft whimper caused Aizawa to turn around and let out a curse. Izuku was trembling in fear, curling himself into a little ball. Aizawa heard the boy whisper.

"I-I change my mind Kacchan. I'll still love you even if you're a zombie. Please, I scared…"

Kacchan moaned and stepped backwards, moving one foot and then the other, facing Aizawa steadily. Aizawa turned back toward the crowd. "I said put your weapons down!"

"Stand down men!" Everyone straightened in attention at the Number One Hero's voice. Izuku froze for a few seconds. Slowly but surely, he looked up, his green eyes wide in amazement as he saw All Might standing right in front of him. His signature smile was plastered on his face as he stared at the boy.

"Hello Young man! Never fear, I am here!"

Izuku promptly squealed.

…

All Might, Aizawa, Nighteye, Nezu, and Hizashi all surrounded the kid as he sat before them; he was eating some of the All Might fruit snacks (All Might looking away in embarrassment) while leaning against Kacchan, who refused to separate from him.

Nezu smiled and walked forward, clasping his hands together. "Hello, young Midoriya. My name is Nezu and I'm the third-in-command of this bunker. The Number One Hero and Nighteye are the leaders in this facility. Can you tell me how old you are?"

"I'll be four in a few weeks. I saw the quirk doctor though because I told my mommy I was feeling a little weird."

Nezu nodded solemnly. "Okay, I understand. Where is your mommy?" Midoriya looked down, reaching his hand out toward Kacchan, gripping onto his shirt. Kacchan let out a comforting growl while he glared hard at the group.

"M-Mommy saw a stranger near me and tried to get him help. He was telling her to leave and take me somewhere safe, but then he sniffed her and he bit her. M-mommy was telling me to run and not look back. I heard a loud noise and a thud. I-I went back and…"

He buried his face in Kacchan's side. The zombie moaned and placed a pale hand in his hair. Izuku shuddered for a few minutes before he took a deep breath. "I was scared so I waited for her to get up. She never did but I saw Kacchan. He just wandered through the door. He looked a little mad, but he sniffed me. It felt tickly, so I laughed. After that, he just made a noise, grabbed my hand, and took me to my new home."

All Might swallowed, looking at Kacchan. "And that home was UA?"

Izuku nodded before grinning. "I'm going to be a hero when I grow up, just like you All Might! Kacchan will be with me too! We're going to be teammates someday!" All Might forced a smile at the child.

"I bet you will, young man!"

Nighteye cleared his throat, glanced at Kacchan for a minute, then looked down at the child. "May I ask what your quirk is, boy?" Izuku shrunk into himself, looking down at the ground.

"…Do I have to tell you?"

Nezu clasped his hands behind his back, calm smile still in effect. "We need to know everything about you, Mr. Midoriya. You are the rare anomaly with how the zombies are protective of you. For us to figure out how we can save…Kacchan and everyone else, we need all the information you can give us."

Izuku shook, gripping onto Kacchan. It was a long minute until the boy finally said.

"I'm quirkless."
