Retire shita Ningyoushi no MMO Chronicle @comic

The past of one of the top five doll-makers in the world. Due to the evil act of those who envied his talent, "Iroha Sakura" is no longer able to move his right hand to its full capacity. One day, Iroha learns of the existence of a VRMMORPG—a virtual world of dolls called "Battle Doll." It seemed that Iroha had regained his own existence, but his encounter with Sara led to a conflict between him and Zik, who was targeting her persistently, and a duel with no chance of victory ends up taking place. Seeing Iroha backed into a corner, his doll begins to develop its own ego. When the doll maker, whose only purpose was to make dolls, comes face to face with Battle Dolls for the first time, an "elaborate fairy tale" is spun!
