Meanwhile in the manga pitchroom:
"So yo have another isekai manga? (sigh) Okay, let hear it."
(excited) "Okay, this is great!. He's going to be another high school kid, but instead of getting a cheat for swords or magic, he's going to have a magic bag that swallows things or summons things."
(dryly)"... Like Doraemon's bag?"
(nervous chuckle) "Uh... yeah?"
"I... LOVE IT. Let's get this into circulation as fast as we can! We'll make a fortune!"
