IORI KANZAKI made his Vocaloid-P debut in January 2014.

In August 2017, he released “Life Hates Me (Inochi ni Kirawareteiru).” Since then, he has released many popular songs.

Since 2018, he has been writing lyrics and arranging all of virtual singer KAF’s original songs in parallel with his own music. In April 2019, he released his first album, Blank page (Hakushi). He reworked his viral hits such as “Life Hates Me,” “That summer is saturated (Ano Natsu ga Houwa Suru),” “I want to be your God (Kimino Kamisamani Naritai),” and other previously released songs by changing the tone and mix, and added a new song, “I Don’t Know What Music is (Ongaku Nante Wakaranai).” He also added “Evolutionary Play (Shinka Geki),“ sung by himself, and added a remix by another new-generation Vocaloid-P, who IORI KANZAKI was eager to work with, titled “I Don’t Know What Music is (Guiano Remix).” The 14-song album is the culmination of IORI KANZAKI’s work to date and can also be considered the first chapter of his career.

In February 2020, his first full-length novel Beast (Kemono), was published along with his EP, Life is a Comedy (Jinsei wa Comedy). In November, Beast was revised, rewritten, and sold in bookstores nationwide as That summer is saturated (Ano Natsu ga Houwa Suru). The book sold out in many bookstores immediately, and within a week of its publication, it was reprinted. It has now sold over 110,000 copies.

In June 2021, IORI KANZAKI formally started his music career with his own vocals. In July, he held his first solo live show. The live performance, livestreamed for free on YouTube Live, attracted more than 16,000 live viewers. A total of 150,000 people witnessed the live performance.

In August, he published his second album, Clumsy man (Bukiyouna Otoko). Almost every song is performed as though with a band, and includes “Life Hates Me” and “That summer is saturated feat. KAF,” which features virtual singer KAF from KAMITSUBAKI STUDIO, and songs which he attempted to play piano while singing. 15 songs are in the album, including new songs.

On November 11th, his new novel Dear You (Shinai naru Anatae) was published by Kawade Shobo Shinsha throughout Japan. It dominated the literature book rankings at various bookstores and was ranked number one across the board.

From August 2022, That summer is saturated is being serialized by manga artist Satoshi Takechi in Monthly Comic Dengeki Daioh.
