RWBY x OC: Puppet Huntsman

Years ago Sada Ningyō was hailed as one of the greatest Huntsmen in the world. Capable of killing hundreds of Grimm, and in her career having one of the highest kill count of Grimm in the world. This was made possible with her unconventional Semblance Energy Threads and equipment Combat puppets, also knowledge of poisons. She was hailed as one of the greatest Huntsmen in the world.

However Sada was still a woman, and she retired when she got pregnant. Now she lives in her home country of Sunagakure, watching over her family. Recently that family has gotten bigger with the addition of her second grand child Ren Ningyō. Ren was the youngest son being born three years after his brother Sasori.

The two brothers were raised together and promised each other they would be Huntsmen too. Of course their grandmother Sada was more than happy to help, and taught them everything she could about puppets and poisons. However a few years later when Sasori was 15 Sada managed to get into the same school she got into Beacon Academy.

...Unfortunately though Sasori was returned to the Ningyō Family dead from a Grimm. This sent the family into mourning, changing everything in the family. Ren was especially affected by this, and trained himself harder, pushing his semblance, and creation of puppets as far as possible. Five years later Ren was accepted into Beacon Academy under Sada's recommendation. Ren is going to be a Huntsmen for himself and Sasori.
