"Alright, let's set out on an adventure towards that tower!"

"Hold on a second. I want you to explain some things first... and before that, something is coming our way."

"Is that so? It might be an enemy. By the way, you seem skilled in combat."

"Is there no tutorial?"

"Such a thing doesn't exist! The first step in this ruined world is a full-on battle!"

"I guess there's no choice then. Let's warm up and go for it."

And so, the adventure in ISEKAI began suddenly."
