Ide Sunosa

Ide Sunosa was the leader of the Ide family during part of the Ki-Rin's Exodus.

Exodus
Sunosa was leading the Otaku when their piece of the Doji's Mirror began to glow with a furious fire in 442, advising the Kami Shinjo was being attacked by the Lying Darkness. The Ide rushed to her aid.

Stronghold of the Darknes
All the Ki-Rin Clan families gathered together after two hundred years, and in a barrened land, similar to those of the Shadowlands they found a stronghold of the Darkness. Shinjo and her followers assaulted it, but exposed their flank and were surrounded. Sunosa and the rest of Shinjo's followers were ordered to flee at once, and to never look back.

Shinjo's lost
The Ki-Rin fled, but Otaku Fujiko hesitated and tried to follow her Lady. Iuchi Suasan did not allow it, she expected Shinjo would honor her promise that she would always return to them. Fujiko gazed back and saw the light that emanated from Shinjo's halo to be devoured by tendrils of Darkness.

Unicorn Clan
Only a single child of Shinjo remained, Shinjo Yonaru. Sunosa and the rest of the family leaders, Fujiko, and Suasan, bent their knee to Yonaru and swore obedience to him. Yonaru decided to drop the Ki-Rin banner because they were no longer Rokugani, but children of a creature that carried both the blood of the Rokugani and the blood of all they had encountered. From that day forward, they would carry the banner of the Unicorn.
