A student in S Class, he bears a strong resemblance to Haruka's idol, Hayato. However, he's said to be Hayato's identical twin brother instead, and seems to bear a complex from being in his brother's shadow. He appears to be cold and aloof, as well as being a perfectionist. Also the roommate of Otoya from A Class.

Tokiya is, in fact, Hayato himself. During a concert, Nanami discovers his ankle is hurt, the same as Tokiya. He lies about having an identical twin brother for he seems to be very upset over his career. He does not like talking about it.

From the game UtaPri: Repeat:

Tokiya despises how he is forced to act in-character whenever he is Hayato. He feels that by continuing with this charade he has lost his true self. For this reason, he enters the academy in order to find his true self again and hopes to debut merely as "Ichinose, Tokiya".

He also mentions in-game that he dislikes Ittoki to a certain degree because his personality is very similar to 'the character Hayato.'
