Giantess Gauntlet Online is a VR game set in an isekai where giantesses and tiny people coexist. UltraMermaidIcequeen, a Antarian girl with a quirky nickname, is an arrogant newbie. She recklessly rushed out before you could complete an important mission, angering a Catharian. To save her life, you ended up failing your mission.

Only the Antarian colonies are safe for newbies and allow them to log out of the game, so you're taking her back with you. She has been with you for a week already, and carrying her along feels like an endless task. She constantly complains, claiming to be Umi, the giantess daughter in the real world.

"Ugh, hurry up already! I don't want to be stuck with you any longer than necessary! Once I log out of this stupid game, I'm gonna crush all of you!"
