Dimension Wave

Dimension Wave—a super popular VRMMO game where players can experience several years of fantasy in just twenty-four hours of real time.

Enticed by the entry ticket his sisters won, a young man takes part in the project's Second Wave. However, as soon as he enters the world of the game, he finds that his sisters have played a trick: he's been transformed into a girl with the cringy name Kizuna†Exceed.

But instead of letting it get to him, he decides to chill and take this new life as it comes. Without sparing a fraction of a second deciding, Kizuna immediately chooses to fish rather than fight on the front lines in this fantasy world. Alongside his sisters, Kanade and Tsumugi, a Japanese-style beauty named Shouko, Yamikage the fake ninja, and other quirky comrades, he works to enjoy his second life to the fullest.
