A giant tentacle monster appeared as water drenched the streets of Z City!

???: Unless you all want to die, listen up!

Messenger Humans! Surrender the earth to the Sea Dwellers! And you will serve as food for-

Yang: Hey Octo Head!

Messenger: What? What is your business? State your name, human.

Yang: Blonde Bombshell, Yang Xiao-Long, A Class Hero, student of the Turtle School, master of several martial arts skills, and the gal who is going to kick your ass!

Messenger: Well Yang Xiao-Long, you should know you have walked into a battle you cannot-

Yang: KAIOKEN TIMES 20!

Messenger: KAIO-WHA-

Yang: TEMPEST KICK!!!

She crushed his head instantly with that attack!

Citizens: It's the Blonde Bombshell!

They started rooting for her!

Yang: Hell yeah! Thank you. Thank you.

Meanwhile...

More of the ocean dwellers continued their attacks as a giant squid monster appeared.

Squid Monster: Stupid humans! The Ocean Dwellers own this planet now! You-

His tentacles were chopped by a guy with a spear!

???: I'm the A Class Rank 11 Hero, Stinger! Nice to meet you!

Stinger: Good thing you guys showed up. I was getting bored. Now who wants a hole in their torso?!

Back with Team (Y/N)...

Genos: Master, your rank has risen to Class C Rank 2.

Saitama: HOW MUCH?!

(Y/N): That means you won't have to do weekly good deeds.

Weiss: There's also the chance you could remain at Class C, but knowing you, that's not your style.

Blake: Hey, I'm getting a call. Yes? City J? No one else is available? Okay. Yeah, we'll be there.

Yang comes in.

Yang: Hey guys, these freaky fish people are attacking and-

Blake: We're aware.

Saitama: Are they strong?

Yang: Don't know. I took out the first guy I saw and he didn't even get to do anything.

(Y/N): Well, here we go again.

With Stinger...

Stinger took down monster after monster, even though he was getting beaten up.

Stinger: Did I do it?

He looked around.

Stinger: YES! I DID IT! I AM AW- AGH!

He was taken out by another one!

Deep Sea King (Leader of the Ocean Dwellers!)

Deep Sea King: You're unpleasant, so die.

Soon...

The Class C Heroes were driving to J City until they saw Saitama and Genos running, and you and the girls flying over there!

C Hero: STEP ON IT!

Back at J City...

The Deep Sea King started to pursue his prey!

And he didn't even realize that someone was watching him from the top of a building!

Hero: So, Stinger was taken out. But, there's only one left. Should I-

Suddenly, Deep Sea King appeared behind him!

The Hero then kicked him in the face, hurting him!

Deep Sea King: That actually hurt.

Lightning Max: When did he get behind me? I- I AM KNOWN AS LIGHTNING MAX! LET'S FIGHT!

Deep Sea King: Fight? Good idea.

He punched Lighting Max in the stomach, sending him flying into several buildings!

Lightning Max: I have to get out of-

Deep Sea King: How about you die?

Lighting Max: LIGHTNING FLYING BACKWARD ROUNDHOUSE KICK!

Deep Sea King just punched him again!

Lightning Max was having blurry vision, and soon he was caught by another hero!

Puri Puri Prisoner (S Class Hero! Put himself in prison, because he likes to go after handsome men!)

Puri Puri Prisoner: I'm the S Class Hero Puri Puri Prisoner! I broke out of prison to see you!

???: A hero doing time? I'm surprised you broke out of prison to fight a monster. And thanks to you-

Sonic appeared.

Sonic: I escaped too.

He was doing time, because of his attack just to get you to fight him. Now he was labeled a villain.

Puri Puri Prisoner: You're Prisoner 4188. I was doing time for 10000 years for getting grabby with men.

Sonic: You deserve to be locked up.

Puri Puri Prisoner: Stand back Sonic Honey, I must avenge the two men who struck my fancy!
