Tenka Shiroboshi (白星テンカ, Shiroboshi Tenka) is a member of Persona, the protagonist team of the anime/manga series, Beyblade X. She fights alongside her Samurai Beyblades and is introduced in the second season as the fourth and newest member of Persona, vowing to defeat her mother, Omega Shiroboshi. Following the title match with Zodiac, Tenka would leave the team to continue being an instructor at the Shiroboshi School.
Appearance
Tenka is a girl of average height, with black and violet hair that she has tied in a ponytail, has violet eyes, and a mark of a white star on her forehead. She wears a hakama attire with three white stars outline with purple, on the top marked with a green "X" on it. Like her mother, Tenka possesses triangular teeth. On occasions, she would wear a white hoodie with a purple star over her hakama attire.
In the Triple Battle, adopting the alter ego of Blader S, her mask is a dark red with a black lens with a gear-shaped pattern on the lens, and a pink "S" at the center of the lens, and a red bean cream sushi is decorated on top of the mask.
When she was a young child, her attire consited of a white shirt with black rims and magenta shorts. During her training in the Shiroboshi School, she wore a white hakama attire with a white and green hair tie.
Personality
When Tenka made her first appearance, she came off as a rude and disrespectful, calling Robin too weak to be a pro, and insulting Multi’s skills both as a blader and Beycrafter. The only one Tenka seemed to respect was Jaxon, but only because she wanted to use him to defeat her mother, Omega. In her "Meet the Bladers" video she was said to be brash, calculating and brutally honest.
Tenka’s time with Persona changed her opinion about them, realizing that friendship helps keep the team together. Tenka also realized the important role that both Robin and Multi play that makes Persona strong.
Like most bladers, Tenka always gives any battle her best effort regardless if her opponent is a newbie or a pro. This mostly likely stems from Tenka’s training at the Shiroboshi School, believing that not giving it her all is not only disrespectful to herself, but also her opponents.

Relationships
Omega Shiroboshi
Omega is Tenka's mother. In the past, Tenka had a good relationship with her mother, learning the Shiroboshi School techniques from her, and even dreaming to inherit Saber Samurai as the next instructor of the school. On the day Omega left the Shiroboshi School and was subsequently banished, Tenka felt heartbroken and gained the strength to defeat both Lantz and Million to inherit Saber Samurai. During one night, Omega secretly offer Tenka to join her to defeat all Pro Bladers in the X, to which Tenka declines in sadness, feeling betrayed towards her mother. Ever since, she was instructed to defeat Omega and refers to her by her given name.
Jaxon Cross
Jaxon is the one whom Tenka seeks out at first, wanting him to join her in a team to defeat her mother, Omega Shiroboshi by promising him to let him battle agains the strongest Blader. Jaxon didn't teach her anything as he does not even know his own strength. He gladly battles with Tenka day and night. As such, she is willing to give up the tie-breaker match against her mother, Omega, leaving the match for Jaxon. In the end, she thanks Jaxon for letting her realise that Beyblade is fun.
Robin Kazami
Originally, Tenka had no interest in Robin, as she perceived him as a Blader who is weak. She often berates him for letting other people's words get to his head. However, over time, Tenka admires Robin's selfless attitude towards his team, stating he holds the team together. Before leaving Persona, she even promises to make sure the students at the Shiroboshi School would also be like him.
Multi Nana-iro
Like Multi, Tenka originally had no interest in her. As Tenka defeated some of Multi's creations, she laid down harsh words towards Multi's skills as a Beycrafter. This leads to Multi going on a self-discovery journey to become a better Beycrafter. Multi would also thank Tenka for motivating her and getting her out of her slump. Following the match against Gordias, Tenka and Multi are on friendly terms, working together to create Persona's Custom Line Beyblades by accessing BEYSA's blueprints for Impact Drake. Tenka also finds a connection to Multi, as they both want to defeat their strong family members. In the end, she respects Multi as a Blader and a Beycrafter, feeling grateful of Multi for creating SamuraiCalibur.
