Kazu (II)

In a world where dungeons have appeared and humans have gained magical powers, the amount of magic one is born with determines their strength. Amachi Kai, a weak conqueror with very little magical power, enters dungeons to earn money for the medical treatment of his sick younger sister, Nagi. But when Nagi’s condition suddenly worsens, Kai is faced with an impossible situation—he urgently needs a massive amount of money for her treatment. Driven into a corner, Kai recklessly joins an investigation into an unknown dungeon with an enormous reward at stake.

A young boy named Mikazuki Kenya was abandoned by his parents, bullied in high school, and left in solitude. At the brink of despair, he encounters a fateful meeting in his only hobby, VR gaming. A meeting with Kaguya and Reina, the heroines from the immensely popular game Knight of Giant. The time spent with the two heroines saved him, and he was head over heels for both of them. However, in the story, one of them is destined to die. To change that fate, he dedicated his life to mastering the game and becoming the strongest in the world. Suddenly, Kenya finds himself entering the world of Knight of Giant?!
