World That’s Fragile, a heavy metal band, was formed since 2012 by 4 friends. It started when Math, the band leader, wanted to play cover of his favorite metal bands. He invited K and Tar as vocalist and drummer, while he himself as bassist and guitarist along with K. Later, the three invited Lim, their kohai from high school, for lead guitar. Lim accepted without question.

Their first performance on stage was at a small bar with less than 10 audiences. None of those lesser than 10 knew them. Many stages followed, WTF started to gain their own, 3-4 fans who gave head-bang on their songs.

3 years passed until WTF was on stage as a Head Lineup band for almost thousand audiences. Now the WTF family reached 50k and it continues to be bigger.
