Choi Ki Su, known mononymously as Kisu, is a South Korean singer, dancer and former member of 24K (투포케이).

He made his debut in June 2012 as part of the acoustic pop sub-unit 4K, which was launched by the agency prior to the full group's debut. They released the single album "Rocking Girl".

He then made his debut in September 2012 as 24K's main vocalist with their first mini-album, "Hurry Up". The group, managed by Choeun Entertainment (조은엔터테인먼트), was never able to find a steady fanbase and opportunities to promote, often spending several years on hiatus before releasing new material. Plus, the agency began making constant lineup changes starting in 2014. He was one of the group's original members.

In December 2017, while the group was on hiatus, he made his debut as a solo artist with the album "Sweet Lie", using the stage name Soo.

He enlisted for his mandatory military service on November 18, 2018, and was discharged on June 19, 2020. Just 4 months before finishing his service, Choeun Entertainment announced his departure from the group to focus on individual activities. After being discharged from the military, he worked as a vocal trainer and music video director and also worked as a guide vocalist.

In January 2021, he released the single "Boy", the first one under his new stage name KISU. He is currently represented by Beyond ENT (비욘드이엔티).
