Yashiro Tsurugi's father, Chikaomi is a famous actor and the owner of a Performa that exceeds ordinary humans. Five years before the start of the game, he performed in an opera alongside the idol Ayaha Oribe when he, and most everyone else in the theater, including Ayaha and Yashiro, was swallowed by a black mist and vanished. Only Ayaha's sister Tsubasa was left behind.
Yashiro later reveals that Chikaomi was responsible for his safety and gave his life so that his son could escape. Chikaomi's strong Performa was taken by Gharnef, but Itsuki, using the power of a Lord, manages to take it back and give it to Yashiro.
In Yashiro's final side story, Chikaomi's spirit returns and reveals that he had been rescued by the Mirage Lon'qu. As a spirit, he has resided in the Idolasphere ever since. Before he passes on for good, he and Lon'qu challenge Yashiro to one final lesson with Navarre's aid.
Chikaomi is a renowned actor and considered one of the greatest. Through his strenuous training, he has achieved his greatness and is proud of his efforts. He raised Yashiro with much the same attitude, challenging his son to be the best of the best.
Tsurugi is the Japanese word for sword.
- Chikaomi is the only parent of any of the main cast to appear in the game.
