Fact (ファクト Fakuto, stylized as FACT) is a Japanese post-hardcore band which formed in 1999 in Chiba Prefecture, Japan. Their music makes use of common hardcore punk and punk rock elements that include fast guitar riffs and a highly melodic style. Clean and screamed singing styles are both used, and gang vocals are present in many choruses. Even though fact is a Japanese band, the lyrics to most of their songs are written in English. The members of Fact have hidden their faces during every video since 2009—wearing traditional Japanese Noh masks during the time they supported their FACT album, but abandoning the imagery in videos the next year in favor of either partially or fully concealing their faces. Their music was used in PVs for Marvel vs. Capcom 3.
