Kars Descends into Demon Slayer

It's a very good book, why isn't it popular? (By the way, is Katz being too calm?)

There is no ultimate biological card value and no robbing mask. Mix in a Dior. Wu Kai cannot evolve into the ultimate creature, but it can evolve. Why not let Wuhan and Kaz fight for the mask? There is no ultimate biological card, and he only traveled to Demon Slayer for non-lethal reasons. Start investigating. The lost mask and ruby. Wu Mei also discovered by accident that the mask could allow him to further evolve. Also relying on his clever little mind. I found a groove on the mask, which should be used to install something. Also started investigating. The mask can allow Muzan to evolve, but it cannot turn him into the ultimate creature.

It's all what I want to see. Anyway, it's a cool word. Katz has always been invincible.

The author's writing style is awesome
