Otomo Tanaka

Otomo Tanaka was the younger son of the Emperor Hantei XV and Otomo Kaoichihime.

Hantei XVI's Rule
After his father retired, his older brother became the new Emperor, as Hantei XVI. His rule quickly became a reign of terror as he brutally tortured and killed anyone he suspected of disloyalty. He even murdered four of his brothers. The only political figures willing to resist the Hantei's increasingly crazed rule were his mother, the dowager Empress Otomo Kaoichihime.

Removing the Emperor
Eventually, Tanaka and the dowager Empress concluded their only choice was to try to remove the Emperor by force, and worked to persuade the Imperial Guard that HanteI XVI had become a threat to the future of Rokugan. When the Hantei discovered his mother's disloyalty he ordered the Crab Clan Champion Hida Tsuneo to murder her in open court. This final outrage was too much, and the Imperial Guard joined Otomo Tanaka in slaughtering both Hantei XVI and Hida Tsuneo.

Retirement
Tanaka, having participated in the coup, felt himself unworthy to hold the throne, and the post of Emperor passed to the Steel Chrysanthemum's young son, Hantei XVII.
