Living with Magical Girls, but I'm a Monster Executive

That was great.

"No time to explain, get on!"

As Cong Yu spoke, he invited Noah into the Jormungandr Train, only to be met with Nagashima Koki's shocked stare—

"Ribbit? Cong Yu had clearly dragged me into the train, so why was he being so nice to this big sister he didn't even know?!"

Didn't that make it look like we were close...

Cong Yu merely glanced at Nagashima Koki without answering, then began controlling the Jormungandr Train as it entered acceleration mode.

Emergency, emergency!

Sprint, sprint! Go!

"Ah... big sister."

Noah was somewhat touched by that form of address. She looked both amused and helpless. "It's been a long time since anyone called me that."

Nagashima Koki: Huh?!

Could it be...

Nagashima Koki was shocked, immediately thinking of someone who often showed up around Doctor's place—as a patient.

Was it the same situation as Rabbit Man?!

Under Nagashima Koki's trembling gaze, Noah sat inside the train and explained simply, "My current gender is... Extinction Formula."

Nagashima Koki: "..."

Nagashima Koki: "???"

Nagashima Koki was a rather knowledgeable child... though she was not really a child anymore.

Still, being called one of the "children" was fine.

Having spent so much time around powerful people, Nagashima Koki had learned many things and had a deep understanding of Extinction Formula.

It could even be said that Nagashima Koki had quite a close connection to Extinction Formula... there were quite a few people around her capable of extinction.

So, after receiving the incorrect information that [the holder of Extinction Formula would have their gender turned into Extinction Formula]...

Nagashima Koki looked at Cong Yu, her expression full of speculation, shock, and 11.4514% alertness.

Cong Yu: "..."

After a brief pause, Cong Yu immediately chopped Nagashima Koki on the head with his hand—

"Duang!"
