3RACHA is a pre-debut unit consisting of Bang Chan (CB97), Seo Changbin (SpearB), and Han Jisung (J.One.) They produce a lot of Stray Kids' tracks together!
Behind their 3RACHA stage names:
CB97: C=Chan/Chris | B=Bang | 97=1997/His birth year
SpearB: Spear=One of the English translations of Chang | B=Bin (So Spearb is another way of saying Changbin)
J.One: J=Jisung | Han=Korean for One (Again another way of saying his name, Han Jisung)
