LatestMasato's party makes their way up the tower. They meet Pocchi on the way up, who tells them that Amante's plan is to clear the dungeon and wish for all mothers to disappear. They have to stop her! Meanwhile, Amante has made it to the top of the 100 floor tower, and defeated the last boss, but she can't get into the wish-granting room. Masato's party arrives and challenges her to a duel. During the middle of the battle, Amante tells Mamako that her presence here is stealing away her son's future! Mamako is caught off guard. But instead, Masato...
Just when Masato thought that a random survey conducted in school was over, he got involved in a secret Government scheme. As he was carried along with the flow, he ended up in a Game world! As if that wasn't enough, shockingly, his mother was there as well! It was a little different from a typical transported to another world setting, but after some bickering, "Mom wants go on an adventure together with Maa-kun. Can mom become Maa-kun's companion?" With that, Masato and Mamako began their adventure as a mother and son pair. They met Porta, a cute traveling merchant, and Wise, a regrettable philosopher. Along with their new party members, Masato and co. start on their journey.

Trivia, insights & behind the scenes
The title spawned the 'Okaa-san Online' meme and became shorthand for overbearing maternal figures in gaming spaces. It oddly predicted the 2020s rise of 'mommy' internet culture.
The light novel author, Dachima Inaka, originally pitched this as a genuine family adventure before editors pushed for more ecchi comedy. The emotional beats that land are allegedly the original vision leaking through.
