Empty. There is space and nothing else.

Because of all the whiteness, like a blank paper. It's hard not to associate with heaven.

Then, two girls noticed the existence of one another.

"You must be the one who brought me here!" They said at the same time, pointing to each other.

"..."

Mitsuha Yamano, her iconic flower and butterfly hairpiece. Her classy leather outfit suggests her recent or already aristocratic profile in action.

"..."

Kaoru Nagase, her scary eyes that are good at showing malicious intent accidentally. She quickly notices the pistol on Mitsuha's right hand.

"Oh, I didn't mean harm…" Mitsuha put her gun away to show genuine intent. "I was… lost here, not sure what to expect then I found you."

"Same… are you indigenous to your world? Or are you Japanese…?" Kaoru can't make up her mind as her classy aristocratic outfit and the use of a gun are conflicting with each other.

"I am… Japanese. Not from your world, your Japan of course." Mitsuha is shocked at first but remains calm. "Do you not know me? Mrs Kaoru?"

"Huh, you know me?" Kaoru's eyes are wide open, almost not believing her name is being called out.

"I see." Mitsuha takes a deep breath. "In my world, you are known as the MC in the novel title:

I Shall Survive Using Potions! "

"Where's your proof then?" Kaoru is not convinced. "The fact you know me is too suspicious…"

"Your power is to make any potion. You like to abuse the fact you can make any size for the container and basically goddess level creation… You also have your item box which stores infinite goods and in the latest chapter, you are still single, wanting to find… love."

"..." Kaoru comes closer, so near that Mitsuha could hear her breathing. Yet, the most frightening thing is her unforgiving stare. "How many secrets you know! What the hell!"

"I'm sorry Kaoru! I mean I read your story!"

"My life is just a story to you…" Kaoru calms herself down. "Am I a fictional character in your world…?"

Mitsuha nods, Kaoru after a few glances, slowly accepting the reality.

"Damn… what in the world is this place then?"

"Some subspace I guess. I have no idea, sorry…" Mitsuha's nervousness is showing, clearly looking away when Kaoru is staring.

"Why are you nervous all of a sudden?" Kaoru with her arm crossed.

"I think I want to test something, please don't be mad."

"Why I would be-"

(Gone.)

"..."

(Reappear.)

"I can travel back to my world, still so-"

"Are you insane! Why would you leave me here!" Kaoru almost cried seeing Mitsuha disappear out of the blue. "I don't want to die here!"

"Me too!"

"AHHHHHHHH!" Both Mitsuha and Kaoru scream, they hear a third voice that isn't their. "Who is that!"

"My name is Mile!" A silver-haired girl jumps out of invisibility and hugs Mitsuha's leg desperately. "Please Mitsuha! I don't want to be alone and sorry to not reveal myself just now because I'm scared of this place!"

"You know my name!" Mitsuha almost falls over.

"You really like your brother! You have powers to travel across worlds! Your story plot is to gather enough retirement money! Please Mitsuha, I know your story!" Mile's sobbing as she trying her best to convince Mitsuha.

"Okay… I think this is-"

"You are called electric miku and for some reason, you keep getting outplayed by the genius princess. Maybe it's a bit much but you keep talking to yourself when things are happening around you. And that includes-"

"Stop! I say stop!" Mitsuha covers Mile's mouth. "I believe you okay?! I will bring you back to your world!"

(Average ability girl… I think I know her.) Meanwhile Kaoru can't believe her eyes, the fictional character just appears in front of her and it's just like how she remembers her. Overpowered, funny and innocent MC, the one who had half of the strength of a dragon.

"Teleport!"

(Gone.) This time, three girls left the mysterious subspace for good (?).
