The Fateful 4

The Fateful 4, colloquially known as F4, are the missing four episodes from the end of S3K3.

Parakyo Films was unable to finish S3K3, officially releasing only 9 of the planned 13 episodes. Despite this, there have been numerous cases of fans claiming to have found full or partial episodes from the unreleased final 4 episodes, but none of these claims have been verified.

These claims caused much controversy within the S3K community, with many fans disagreeing over the existence of these 4 episodes. The continued controversy and mystery surrounding these episodes led to them being referred to as the "Fateful 4," sometimes shortened to F4.
