Giga (previously Giga-P), is a producer, composer, and utaite. He is best known for his techno and pops works and his high-energy arrange covers. He mainly uses Len and Rin, though he also uses Miku, GUMI, Luka, IA, and Lily. He has collaborated many times with Orebanana-P, to the extent that together they are known as "Gigabanana".
His notable songs include "Gigantic O.T.N", "Kiddie War", "Resonate", and "BRING IT ON".

Giga-P has earned the title 'Legendary LEN Master' for several of his works, such as "Tululila Talila Tulula", and has also earned the title 'Legendary Kagamine Master' for his cover of "World's End Dancehall".

In March of 2016, Giga, along with Reol and Okiku, have signed to become artists under TOY'S FACTORY. Giga has not made any formal announcements saying he has retired from Vocaloid but he is still active in the music community.

In August of 2017, Giga announced that their unit, REOL, will be disbanding due to creative differences. Their last concerts were held in October.

In May of 2018, it was announced that Giga would be producing Rin and Len's 10th anniversary theme for Magical Mirai 2018, BRING IT ON. He later then produced a song in collaboration with Umetora where he did the arrangement and tuning, which was his first Vocaloid related work in 4 years. Read more on Last.fm.
