For decades, mysterious dungeons have been popping up all over the world. The resources found within these dungeons have completely reshaped human society, turning life upside down. In this world, Tsukasa Kisaragi, a high school student and active dungeon explorer, harbors a lingering regret. Back when he first got his explorer license, his social anxiety held him back from forming any party or making friends. But whether it was a blessing or a curse, Tsukasa was born with an extraordinary talent for dungeon exploration. He was so good at it that even solo, he could conquer any dungeon without breaking a sweat. He got used to going it alone, and before he realized it, he had become one of the few EX-rank explorers in all of Japan—so rare they could be counted on one hand. Despite his incredible skills, Tsukasa kept his true identity hidden, living a low-key life. But one day, he stumbled upon something that would change everything: dungeon streaming. And from that moment, his world would never be the same.
"…So, it's time for a strategy meeting."
: He's getting used to streaming, huh?
: This is only his third time.
: What do you mean "so"?
: This guy is always so abrupt.
: Do whatever you want.
Today, instead of a dungeon stream, I'm streaming from home as a new challenge. Since my plan to hire only dungeon streamers fell through, I thought I might as well consider hiring virtual streamers too. So, I'm thinking of trying out some game streaming in the future.
"Remember how I mentioned wanting to start a company to manage dungeon streamers?"
: Did you?
: I don't remember.
: Did he say that?
: No clue.
: I think he mentioned it before diving into the deep floors.
: Ah, yeah… maybe?
"You guys are so nonchalant."
: You're one to talk.
: You're the last person who should say that.
: Kisaragi-kun, really?
: The master of unplanned actions is speaking?
