Sayoko Tsukikage

Given to two Skull Monsters and placed under the protection of Amulet Bohma, she ultimately was forced to wander as a baby for nearly the entirety of the next 20,000 years until the Bohma revival drew close enough that her foster parents took human form and decided to raise her as Sayoko Tsukikage (月影小夜子Tsukikage Sayoko), a normal human girl who would believe herself to be human until the day her power would finally awaken, upon her "18th birthday". She ultimately grew up in an area near Musashino Academy, where she would go to high school unknowingly alongside several who had encountered the enemy of the Bohma, the fairies, in their childhood and would ultimately become tied to becoming the Turboranger fighting against the Bohma threat.

Sayoko's 18 years prior to the awakening of her Bohma power were rather normal, with several encounters with the future Turboranger, including a meeting with a young Shunsuke Hino at the beach while a little girl and as a fan of Riki Honoo's baseball team. She believed herself as human and gained the emotions and empathy that a human girl would hold. However she also had a great deal of angst and lonliness, due to being looked down upon and bullied for her quiet nature and her unknown origin. It only became furthered as the day of her birthday arrived and Sayoko's power began to manifest, causing others to treat her as a freak. While Riki tried to help her overcome this, her Skull Monster parents tried to attack him due to his association with the fairies and force Sayoko into embracing her destiny as a Wandering Bohma and to show loyalty to the Bohma tribes. This is furthered with Hikaru Nagareboshi, likewise a Wandering Bohma known as Yamimaru who had actually seen Sayoko in a strange dream just before several greater Bohma generals started to fall as prophetized. When her "parents" and her guardian Amulet Bohma are killed by the Turboranger, Sayoko decides to see to her destiny, taking up Nagareboshi's offer and binding them by a "red thread of fate" that fully awakens her power as Kirika.
