20 years old.

Is one third of LME's popular talento trio, 'Bridge Rock', who are the hosts of a new variety show; which features the character Bo (aka Kyoko).

Though all of Bridge Rock share the same surname, they are not related.

Their name is taken from Ishi (rock) and Bashi (bridge), flipped round.

Hikaru seems to like Kyoko and has asked her out several times, only to be unintentionally knocked back by an oblivious Kyoko.
