Yashiro Nanakase/Story

=The King of Fighters series=

Past
The true origins of the Orochi fighter known as Yashiro are shrouded in mystery. At one point, he formed a music band with Chris and Shermie called "CYS" (based on the first letter of the name of each member), with him playing the guitar. They were preparing to perform when the club they were scheduled at canceled them in favor of a jazz band featuring Iori Yagami. Upset at their loss and angered by "the man with red hair", Yashiro and his band steal the invitations from the American Sports Team (Heavy-D!, Lucky Glauber, and Brian Battler) and enter the KOF '97 tournament in order to get their revenge against Iori.

The King of Fighters '97
During the tournament's duration, the Orochi blood within Yashiro awakens as he and his friends remember their duties as three of the Four Heavenly Kings of Orochi and work to resurrect their lord by gathering the fighters' own energy. Near the end of the tournament, both Yashiro and Shermie commit suicide in order to transfer their remaining energy into Chris and because of this, Orochi is able to return to the world while using Chris' body as the host, but Orochi itself is re-sealed again by the Three Sacred Treasures: Kyo, Iori, and Chizuru.

The King of Fighters XIV
Verse's defeat at the end of The King of Fighters XIV had released numerous souls and has caused many who have perished throughout the series to be brought back to life. Yashiro is confirmed to have been revived, along with his comrades Shermie and Chris. This further evident in Shermie's ending in SNK Heroines Tag Team Frenzy, and his revival is eventually showcased in his proper return in the fifteenth KOF tournament.

The King of Fighters XV
Yashiro is more than eager to settle his score with Iori, but after having done so, he is now aware that Iori is not only his rival in the music scene; he is also an obstacle to Orochi's revival.
