- Description from novelbuddy

Hanazawa Hanako was a young otaku girl, technically a hikikomori, a degenerate, and a netizen. She died though. (LOL)So naturally she got yeeted to a fantasy world to save it from the demon king.When asked what buff she want: “Just give me the whole Internet then.”

A Consort seeks prosperity.A Shepherd cloaked in yellow wages war.A Prosthesis-wielder cries out for retribution.Shadows tremble in the depths, encompassed worlds obscuring the many dangerous secrets of history. Might they be unraveled, all ways of life would be threatened. But to climb higher requires risks, to seek the light requires a Gambit of Lifetimes.Only when one determines themselves capable of risking it all, can all prosper.

After transcending to a new world, Ye Xuan miraculously obtained the Swallowing System.
