Taiki Himekawa

Taiki Himekawa, né Uehara is a character in the Oshi no Ko manga series. He is an award-winning stage actor affiliated with the Lalalie Theatrical Company. It is later revealed that he also Aquamarine and Ruby Hoshino's older half-brother, conceived when his mother cheated on his legal father with their father.

Appearance
During his first appearance, Taiki looked so similar to Gorou Amamiya that Aquamarine Hoshino became unsettled. Otherwise, he had disheveled black hair, stubble, and square-rimmed glasses. Preceding the Tokyo Blade theater play, he shaved his stubble and tamed his hair.

History
Not much is known about Taiki except that he was born to Hikaru Kamiki (when he was 11 years old) and Airi Himekawa, who was married to Seijuurou Uehara at the time.

Etymology

 * The name Taiki means "big, great" (大) (tai) and "brightness, radiance, shine, sparkle, gleam, twinkle" (輝) (ki).
 * Taiki's surname Himekawa means "princess, young lady of noble birth" (姫) (hime) and "river, stream" (川) (kawa).
 * His original surname Uehara means "above, top, upper" (上) (ue) and "field, plain" (原) (hara).

Trivia

 * Taiki does not own eye contacts and chooses to deliberately go without them. When portraying characters without glasses, he will simply not wear them. This is because, according to his belief, actors are able to portray characters only using their movements. And even without glasses he would be able to make to their general movements.
