"You guys are shining. However......You're not an enemy of ours, for sure." - Tatsumi Rui


Tatsumi has bright blueish-green eyes and light blonde hair. His bangs are swept across the left from the middle-right. The right side of his bangs is shorter than the left.

In his school uniform, he wears a light grey hoodie over his shirt in place of the standard vest and his blazer is worn unbuttoned.

In his training attire, he wears a white zip hoodie with black trims on the pockets and a black line that starts at his shoulders and goes all the way down the sleeves. His hoodie is zipped half way and he wears a bluish-green shirt inside. He wears a pair of white pants which stop below his knee and a pair of white dancing shoes.


As the leader of Team Hiragi, Tatsumi is well respected by his peers. He is depicted as humble and kind, but still confident. He gets along with members from both Team Hiragi and Team Otori.

However, Tatsumi has also shown to have a more serious side. While he acknowledges Team Otori's potential as formidable rivals, he also reaffirms that they neither a threat nor enemies. Furthermore, he is very perceptive - he was the only one to understand that there was a reason why the members of Team Otori were chosen.


As a child, Tatsumi used to be shy and frail. Sawatari used to take care of him whenever he was sick. They attended the same middle school together (along with Nayuki and Tsukigami) and were nicknamed "Princess" and "Knight".


Nayuki Toru

The two knew each other from middle school and are able to exchange greetings to each other.

Tsukigami Kaito

The two knew each other from middle school. Tatsumi acknowledges that Tsukigami has talent as seen after the incident with Ugawa when Tatsumi apologises for the actions of his teammates.

Hoshitani Yuta

Hoshitani and Tatsumi sign for rivalry.

Hoshitani first met Tatsumi at the information session for the Newcomers' debut performance. However, the two didn't get the opportunity to exchange words. It isn't until the summer training camp at the Hiragi family villa that they have a proper conversation.

Although they are both leaders of a Star Team, they contrast vastly in terms of skills and attitudes. Tatsumi finds that because Hoshitani doesn't know many famous works, playwrights, or directors, he is pure and interesting. However, he lacks as a leader and will eventually reach his limit, especially since he can't turn to the high schooler he admires for advice. In response, Hoshitani declares that despite his shortcomings, he doesn't know a way to give up his dream. Tatsumi became even more impressed, calling Hoshitani and his team's performance wonderful and admitting that he can't deny that something about them shines. Their talk is cut short when Tatsumi is called away by Ugawa. Before he can leave the room, however, Hoshitani expresses his hope that their teams could act together again. This leads to Tatsumi reminding him that the day's earlier events were coincidental and that tomorrow, they would return to fighting for the top spot. Even so, the two end on good terms, as Tatsumi looks forward to Team Otori becoming formidable rivals.

Sawatari Eigo

Sawatari discussing with Tatsumi.

Because their families are close friends, Tatsumi and Sawatari have known each other since birth. They are childhood friends, classmates, roommates, and teammates. Sawatari used to take care of Tatsumi whenever he was sick (something that has continued years later). Sawatari believes Tatsumi is worthy of being a king. The two frequently exchange remarks with one another.

Ugawa Akira

Ugawa completely respects Tatsumi and calls him Tatsumin. He takes Tatsumi's scoldings seriously as seen when he stopped taunting Team Otori after receiving a look from him.

Although Tatsumi acknowledges that Ugawa sometimes says too much, he will still stand by him, saying he's not a bad person.
