Otaku Shiko was the daughter of the Unicorn Clan Thunder Otaku and took up the position of Shinjo's right hand when her mother entered the Shadowlands in 42. Shiko then joined Shinjo when the Ki-Rin's Exodus began in 45, and eventually founded the Otaku family. She lived a long life, due to her proximity to the Kami, but died in 238 after splitting away from Shinjo in an attempt to find a way back to Rokugan. Shiko later returned through Oblivion's Gate in the 12th century, took the name of Utaku Shiko, and caused some contention as to who should rightfully lead the Utaku family.
