Seiya Sena is the husband of Nagisa Sena (a model turned actress and a bit of a spoiled princess that he happily got married to) & the father of Shougo Sena and Izumi Sena. He is a stage actor with a focus in musical theatre. He was scouted by his own mother and debuted as an opera singer. He is the founder of SenaPro, the Sena family's personal agency.

Even though the marriage between them was ostensibly because Nagisa relentlessly pursued Seiya after going to see one of his musicals and falling in love with him at first sight, Seiya, too, fell head over heels with the beauty touted as Japan’s foremost actress the second he laid eyes on her. He truly believes that a happy wife leads to a happy life.
