After the incident about the deep sea king, Saitama become Class-B, Nancy was very happy of that news.

But one day, they were invited to Bang's Dojo.

His top disciple Charanko was blushing at the sight of Nancy who was acting bold and boyish.

*Bang's Dojo*

Genos: "So old man, what do you want from us?"

Bang: *brushes his mustache* "well you might be interested in my martial arts?"

Saitama: "I don't need like that to be honest"

Charanko: "hey stop being disrespectful to Bang Sensei, he is the most respectful and feared martial artist!"

Bang: "enough Charanko! Those people are stronger than me!"

Charanko: "b-but..."

Nancy: "yeah, listen to your master"

Charanko: "don't talk to me!" *Looks away while blushes*

Saitama: "hey your face is overheating, what's up? The weather was fine"

Charanko: "n-nothing! That's none of your business baldy!"

Genos: "is this your best disciple?"

Bang: "yeah, he is...my other disciples are leaving me behind.."

Genos: "but why?"

Nancy: *listens and curious*

Bang: "I have a top disciple before who went rampage in my dojo, I kicked him out after that, in result all of my disciples start to leave after getting beaten up by him"

Nancy: "hoh? Is he strong?"

Bang: "well, he is..."

Saitama: "if you are only inviting us for being one of your disciple, well we might just leave for now--"

Someone just barges, a guy in suit who is part of hero association headquarters, gasping air from walking up in the hill since Bang's Dojo is in the top of the hill.

HA Assistant: "M-Mister bang! Emergency meeting! All Class S are called for the meeting--"

Genos and Nancy: "???"

HA Assistant: "oh, I'm glad 2 more class S is with you, it saves my time.."

Genos: "Sensei, since we are called, do you want to come with us?"

Nancy: "yeah he is right, if anyone disrespect you there, I'll beat them" *smiles boldly"

Saitama: "stop that little sis, and I'll come since my sister and Genos is also coming"

*Inside the Hero Association HQ halllway*

A samurai guy greet Bang and others.

???: "Oh mister Bang" *grins with a toothpick in his teeth*

Bang: "mister Atomic Samurai! Nice to meet you"

Atomic Samurai: "so this guy is Genos and that woman is Nancy, and this guy is..." *Looks at Saitama*

Bang: *introduces Saitama* "this young lad is Saitama, a B class that will soon rise to the ranks of Class S"

Saitama: *offers shakehand* "hello old man, I'm Saita--"

Atomic Samurai: *sweep Saitama's handshake* "I only respect the strong, and beside I'll greet you if you are one of us, and I am not old, I am still in my 35s--"

Nancy: *death glare with a sinister smile* "hey old man, I suggest you not to insult my brother unless you wanna get beaten up by me"

Atomic Samurai: "hoh? Is that a threat?" *Smirk*

Bang: "miss Nancy, please calm down"

Genos: "calm down miss Nancy, unless you wanna trigger your rampage on what sensei said..."

Saitama: *facepalming and embarrassed of his sis* "please stop acting like that..."

Nancy: "well, if you insult and disrespect my brother, well I might say that, YOU WILL BE MY ENEMY AS WELL" *sinister smile*

Saitama: "calm down sis, are you gonna embarrass me here, you got demoted recently unless you wanna become a class A?"

Atomic Samurai: "well he has a point since you have a bad attitud--"

Nancy: "WHAT WAS THAT?" *sinister look while leaking squashing pressure*

Atomic Samurai: "..."

Bang: "atomic Samurai, just don't provoke her, she is a short tempered girl"

The angry Nancy drags the poker look Saitama.

But before they can enter inside the main meeting room, someone stops them.

???: "why there's a class B inside this building? Are you kidding me!? You are not included in the meeting get lost"

Nancy: *looks at her* "hey little brat! Stop mocking my brother unless you wanna get beaten up"

???: "you must be the newbie class-S who isn't aware of my title?" *Smirks and acts sassy*

Nancy: "and who the fuck are you?" *Grabs Saitama's wrist tightly while talking to her*

Saitama: "come on just calm down sis, just leave that sassy kid alone, don't you trigger rampage here..."

???: "s-sassy kid!? I'm gonna tell you I'm 28 years old! My name's Tatsumaki! A rank 2--"

Nancy: "so what if you are a rank 2, you won't beat any of us anyway" *smirks*

Tatsumaki: "heh~? I think I need you to put to your own place" *Glows green aura*

The entire building shakes from Tatsumaki's power.

Nancy's expression turn darker as she notice the murderous intent.

She would leaked her Half Released aura that would make the entire building tremble again, Tatsumaki flinches from Nancy's power but she doesn't surrender acting so high infront of Nancy just to show she is more powerful than Nancy.

Nancy: "you are boasting your title being the rank 2 class-S..."

Tatsumaki: "because you are a rank 18 shit who got demoted for abusing a kid! Pathetic~"

Nancy: "well that may be the case but I am formerly rank 1 class-S in my country before I retire, so I suggest you to stop acting so high unless you get beaten--"

Saitama covers her mouth and drags her instead.

Nancy: "mmmmgghfhkssj???" *Embarrassed because got lifted by her big bro*

Saitama: "as a big bro, I'm gonna discipline you..." *Carries Nancy to avoid trouble*

Tatsumaki: "humph! I'll remember your face you annoying woman"
