A/N: This is a sequel to my other fic "Let Me In, I'm Quirkless."

Katsuki made Izuku spill the beans on what's bother him.
"So a Yakuza leader is abusing a kid?" Katsuki said.
Izuku nodded and said, "You can't tell anyone!"
Katsuki gently placed his hands on Izuku's shoulders, looked him straight into his eyes, and promised not to tell anyone.
"I told Kai not too-" Katuski muttered.
"Kai? You know him?!" Izuku questioned.
Izuku was taken back when Katsuki growled at him and told him to forget about it. He had a bad feeling about this.

It was the morning of the Shie Hassaikai Raid.
Izuku and Mirio arrived a little bit early at the rendezvous point to meet with their Boss, who was going over the strategy plan with them.
"That's Plan C, if anything goes wrong we will-"
"Um...Who's that?" Mirio asked, pointing at the security feed on the tablet Sir Nighteye was holding.
Izuku gasped when he saw Katsuki in his hero uniform.
"Isn't that...your classmate?" Mirai asked Izuku as he remembered the Sports Festival.
"Wait, what?!" Aizawa shouted.
He grabbed the tablet out of Sir Nighteye's hand and was furious.
"How did he know the location of the Shie Hassaikai?" Aizawa questioned.
"Midoryia?" Sasaki snapped.
"Um…" Izuku stuttered.
The two older men gave Izuku the stink eye and caused the greenette to buckle under pressure.
"It's not my fault! I swear! He made me-"
Both Izuku and Aizawa were interrupted when their phone vibrated.
.
.
.
Katsuki:
I will be in and out in 10-15 minutes.
Their phone vibrated again when they received another message from the blonde.
Katsuki:
Call a couple of ambulances. The Yakuza will need them.
.
.
.
Both Izuku's and Aizawa's eyes widen when they realized Katsuki was about to get himself killed.
"We have to go in now to rescue him!" Mirai shouted.
"But everyone is not here, Sir." Mirio said.
Mirai shook his head and sighed. He never saw anything like this in his foresight.

"Boss! Boss! He's here!" Mimic cried.
Kai eyes widen when he realized who "He" was.
"Oh no. How did he get past our defenses?!" Kai questioned.
"I have never seen anything like it before. He was a one-man army."
Chill ran down Kai's back. He knew he was no match for an angry Bakugou.
"Get Eri! We got to go-"
"Going somewhere?" Katsuki interrupted.
Both Kai and Mimic gasped. Mimic quickly hid behind Kai and hoped by looking small and vulnerable, Katsuki would spare him this time.
"What do you want from us?" Kai sobbed.
He still had nightmares of the last time Katsuki broke into the Yakuza complex. They had to move locations because of him. He was able to heal everyone's injuries but not their mental scars.
"The girl." Katsuki hissed.
"You can have her!" Kai pleaded.
Chisaki knew the girl wasn't worth it anymore.
A smile formed on Katsuki's face.
"Oh no. He's showing his teeth! " Kai thought.
He was going to have nightmares for the weeks.
.

"What the hell happened here?!" Sir Nighteye said.
The Complex was full of injured Yakuza members. Most of them were unconscious with burn marks on them. It was a good thing they already have some ambulances on standby.
"What is wrong with your students?" Rock Lock asked Eraserhead.
Eraserhead shrugged because he kind of saw this coming. The blonde displayed explosive behavior. He was always a ticking time bomb.
He was just impressed Bakugou didn't kill anyone.
"Oi. Deku." Katsuki said.
The Heroes jumped back as the blonde teen appeared out of nowhere behind them.
Katsuki was carrying Eri on his back.
"Did...Did you single-handedly defeat the Yakuza with just your quirk?" Sir Nighteye asked.
The Heroes team split up and scouted the complex only to find more injured Yakuza members.
With a grin on his face, Katsuki said, "Yeah."
.
.
.
After the Hero Commission found out, they decided to give Katsuki his full hero license and pardon any trouble he would get into for that fiasco he just pulled.
However, Aizawa (and later Mitsuki yelled) at Katsuki for not following protocol. Katsuki swore he probably got eardrum damage from their yelling but it was worth it since he saved both Eri and got the entire Yakuza arrested.

A/N: I'm having the time of life adding ambiguous backstories and endings to my stories.
By the way, what do you guys think happened the first time Katsuki met the Yakuza?
