'''(Heivia/Ground’s Nir)

“The bottleneck here is this weird skin you called Cultivated Muscles,” said Heivia while wearing that handsome skin. “There are two versions: the handsome boy from Index and the pig-faced giant from Boo Boo. If it was just the latter, we could say it was prepared in advance and then the culprit messed with the Gate to come to my world, but the handsome skin gets in the way of that. There’s no explaining it.”

“Hold on. Are you saying…?”

The handsome skin nodded at red armored and miniskirted Beatrice.

“Yes. It started with someone from this Boo Boo World. …But they failed. They connected the Gate and came to my world, but I’m guessing they didn’t stand a chance there.”

Thinking about it, it was obvious.

Things might be different with each world’s special abilities added in, but in pure physical fights, Heivia’s world was the most dangerous. They had masses of nuke-resistant armor with main cannons powerful enough to blow each other away in a single shot. Those Objects were scattered all over the world. It had such a strong stench of death hanging over it that it almost seemed darkly humorous. He could picture the look on the would-be invader’s face when they first ran across one of those. If you could not overcome each individual death without making it into some kind of beautiful story, you could never get by in that world.

“And when one side fled back home, it was time for the other side to go on the offensive,” said Heivia. “I don’t know if they couldn’t close the Gate they had opened or if it was analyzed over a short period of time. Whatever the case, someone from my world attacked Ground’s Nir. Now, what would the ‘original cause’ do? They already knew far too well that they could not beat this opponent in a fight…so they avoided a fight. They fled to somewhere other than Ground’s Nir or my world.”

“You mean…somewhere we haven’t seen yet?”

“Yes. It was probably the world that Quenser was dragged to: Academy City.” Heivia slowly took a breath. “That means they’ve moved back and forth between two worlds with Ground’s Nir in the center. And the Cultivated Muscles are based on the cells they acquired doing that. Simply put, they were souvenirs of their world invasions.”
