Saitama In Another Dimension?

Rainy Day

Saitama is seen jogging through the pouring rain with his usual expression.

Saitama: "I wonder where the monster is..."

He eventually stopped running when he saw an open convenience store with the clerk still in there waiting for customers. Saitama, a bit curious, entered the store and looked around.

The clerk was a young man who looked like they just hit their 20s. Their face could very well rival the looks of the most popular hero, Amai Mask. His eyes shined a light crimson-red as he locked eyes with Saitama's bland eyes.

Clerk: "Hello sir, how can I assist you today?"

Saitama: "I don't have money on me... but I'm wondering why you're still working. You know there's a monster around right?"

Clerk: "I could say the same to you. Isn't it a bit dangerous to come into a convenience store while a monster is attacking?"

Saitama: "Well, I just got accepted as an A-rank hero. So I'm here to kill that monster"

Clerk: "A-rank? Too bad, only an S-rank could hope to defeat me"

Saitama blinked.

Saitama: "Eh?"

Clerk: "Surprised? I am a monster who is here to kill all humans in this city"

The 'Clerk' walked from round the counter and faced Saitama.

'Clerk': "Hmm... Despite exposing myself as a monster, you have not reacted at all"

He frowned.

'Clerk': "How boring"

Saitama blinked when almost 30 tentacles burst from the man's back.

'Clerk': "Just die will you?"

As he said that, Saitama was in confusion.

Saitama: 'Why are the monsters so human-like now?'

The tentacles were all launched toward the hero only for him to dodge all of them and slap the monster out of the building. The amount of power from the slap damn near demolished the store as the monster was launched upward into the air.

Saitama: "Hopefully I don't have to pay for that"

Saitama carefully lifted a shelf back up into a standing position and dashed out of the store.

Meanwhile, the monster conveniently crashed into the evacuation shelter. The monster stood up in pain and observed the multitudes of civilians inside.

'Clerk': "I seem to have lost my way-"

He stopped when he saw their horrified looks. He looked to the side to see his tentacles on full display.

'Clerk': "Oh well...."

With no warning, he shot them forward, intent on skewering all of them. Fortunately, a gunshot rang out and the monster's head exploded into gore.

The civilians gasped and looked to see the well-known S-Class hero holding a smoking shotgun. Ignoring their awed expressions, the S-Class lit a cigarette with a sigh.

This hero was Zombiewoman. She is well known for her rumored immortality. Being able to survive and heal from wounds that would otherwise kill your average human. Her weapons of choice were fairly normal. Firearms and sometimes a knife or axe.

Zombiewoman: "Surely that wasn't the dragon-level threat"

??: "You'd be correct to think so"

A large fish-like creature loomed over them with a sickly smile. The civilians in the shelter were in shock. How did they not notice it until now!?
