The Hero Certification Exams were going on as you, Ruby, Weiss, Blake, Yang, Saitama, and Genos all signed up. 

There was a physical exam and a written exam, and well, you all crushed they physical exam! 

For example:

1 Hour Later... 

(Y/N): YES! YES!!! YES!!!! 

Ruby: What is it (Y/N)? 

(Y/N): I SCORED 100! AND I'M IN S CLASS! 

Weiss: Well of course you were going to be in the best. I wouldn't expect anything less from the man who killed some of the most dangerous and villainous beings to ever exist, and amass so many allies throughout 3 years in his life. 

Yang: And conquered and claimed several women as his girls. 

Ruby: Yep, that's- EEEE! I'M A CLASS! 

Weiss: (Sigh) So am I. 

Blake: Me too. 

Yang: Damn it! A. 

(Y/N): Hey, it's better than B. 

Genos: It is still a fine score, indeed. 

Ruby: How about you Genos? 

Genos: I scored 100 and I'm also an S Class Hero in rank. Master? 

Yang: Well Saitama? 

Saitama seemed upset. 

Saitama: I passed with 71 points. I'm a C Class. 

(Y/N): WHAT?! 

Ruby: OUTRAGE! 

Genos: I will lodge a complaint with the testers. 

Saitama: NO! THAT'S EMBARASSING! 

Announcement: Mr. (Y/N), Ms. Ruby, Ms. Weiss, Ms. Blake, Ms. Yang, Mr. Genos, and Mr. Saitama, a seminar for successful applicants is beginning at 4:00 P.M. Please come to Hall 3. 

(Y/N): Well, let's go! 

At Hall 3... 

You guys met another hero of the Hero Association. 

Snek

Snek: Congrats on passing. Though one of you got through on a fluke. Work hard so your good luck doesn't go to waste. 

Saitama was chewing gum during the seminar. 

Snek: Don't get cockY! From now on, you must life as befits heroes! Your faces will be on the Hero Association's Official Website! 

Yang: SERIOUSLY?! AWESOME! 

Snek then got up and did a pose. 

Snek: Aim to become magnificent heroes like me! 

(Y/N): Well, since we're high ranked, that means we're obviously going to d- 

Saitama blew a bubble and it popped over his face! 

Snek got annoyed and- 

Snek: (irritated) You know, Class A Heroes have some influence over the association, but numbskulls can lose points and rank at any time! Don't forget it! 

Soon... 

Snek: Those newbies. I swear, did they actually pass? That man seemed to enthusiastic, some were indifferent, that youngest one was an idiot, and- ARGH! They don't even recognize me! AMATEURS! I swear, all of them are going to die in no time. 

Official: No, (Y/N) and Genos passed the written and physical tests with perfect scores. We haven't seen such a feat in two years. They both made it to S Class, it's outstanding for newcomers like them. And those four, Ruby, Weiss, Blake, and Yang, they have all made it high in both the physical and written tests, adding more to the A-Class which we haven't had much of. As for Saitama, while his written test and essay was dreadful, he scored the full 50 points in physical strength. Overall, he barely scaped by, but in nearly every physical challenge he surpassed all the previous records. Snek, (Y/N), Ruby, Weiss, Blake, Yang, and Genos have all surpassed you. And Saitama will too eventually. 

Snek had a look of horror on his face. 

Meanwhile ... 

You, the girls, and Saitama parted ways with Genos and walked home. 

Ruby: This is so exciting! 

Yang: Say (Y/N), you think you can convince the Association to let us go with you to see the other S Class Heroes? 

(Y/N): Hmph, I'll definitely try on that. I'm actually curious on how they're going to be like. 

Blake: How are the other A Heroes like? Maybe they're just as formidable as- 

Snek: LET'S CONTINUE THE SEMINAR! 

Snek appeared. 

(Y/N): You again? 

Snek: In business, quite a few heroes are worried about getting surpassed in rank! So I will crush you all n- 

In one second, you all knocked out Snek ... 

Weiss: Ugh, if you're going to be a hero, act like it. 

Snek: Ow ... 

A kid with a big chin passed by. 

Kid: Lame!
