Biography

Tenka Shiroboshi is an instructor at the Shiroboshi School and daughter of the rogue master Omega Shiroboshi, joining Persona as its fourth member specifically to defeat her mother. Initially brash and dismissive of Robin and Multi, she softens as she comes to value their teamwork and grows especially close to Multi through their shared family conflicts. She wields the family heirlooms Steel Samurai and Saber Samurai, later Calibur Samurai, and briefly poses as the masked Blader S in a triple battle before returning to teach at her school.

Appearance and personality

What They Look Like, and How They Behave

Tenka, an average-height girl, wears her black-and-violet hair in a ponytail, with violet eyes and a white star marked on her forehead. Her hakama carries three white stars outlined in purple with a green 'X' at the top, and like her mother she has triangular teeth; over the hakama she sometimes adds a white hoodie printed with a purple star. As her alter ego Blader S in the Triple Battle, she dons a dark red mask with a black, gear-patterned lens, a pink 'S' at its center and a red bean cream sushi ornament on top. As a young child she wore a white shirt with black trim and magenta shorts, and during her training at the Shiroboshi School she dressed in a white hakama set with a white-and-green hair tie.

Tenka's first impression is a rude and dismissive one, dismissing Robin as too weak for the pros and mocking Multi's ability both as a Blader and Beycrafter. Jaxon is the only one she initially respects, and only because she means to use him against her mother, Omega; a 'Meet the Bladers' video sums her up as brash, calculating and bluntly honest. Her time with Persona shifts her outlook, teaching her that friendship is what holds a team together, and she comes to recognize how much Robin and Multi each contribute. Whatever the opponent's level, she always gives a battle everything she has, a standard rooted in her training at the Shiroboshi School, where holding back is treated as disrespectful to herself as much as to whoever she's facing.

Schooled Samurai swordplay beats Meiko and Eight Cross, and her resolve deepens with Persona, though her mother still sweeps her in the match that matters.

Claims We Could Not Check
