Kim Seok Man, known professionally as WillyK, is a South Korean musician and member of CRACK SHOT (크랙샷) and CRAXILVER (크랙실버). He graduated from Seoul National University affiliated High School and later obtained a bachelor's degree in Applied Music and Saxophone from Yeoju University.

In 2013, he formed CRACK SHOT with his college friends and won several competitions before all members (except Vincent) enlisted in the military, putting the band on hiatus.

The band officially debuted in October 2015 with the digital single album, "Midnight Crime" with him as the leader and guitarist. They decided to enter the show "Super Band 2" in 2021, ending up as the winners. The 4 original members were joined by Oh Eun Chul during the competition and used the name CRAXILVER. After the show, they were supposed to permanently change the band name but so far have not done so. They perform as CRACK SHOT when Oh can not join them and as CRAXILVER when he does.
