Mirror Rumor

The mirror rumor is a myth amongst many high school students that, on a rainy night, a fogged up mirror will show you your soulmate. However, instead of your soulmate, people watching see the latest victim in the Mirror World. Those that watch see the shadow of the person taunting the victim.

In Shattered Perceptions
The mirror rumor has been tried numerous times by various people. The first noted example was the night Hikaru Masuko went missing. That night, Lysistrata, the manifestation of Hikaru's repressed side appeared, revealing that much of Hikaru's exterior is a facade for what he was hiding. Unbeknownst to many, Zayn Nader also saw this, and tried the mirror rumor again the next day, but was only able to see a glimpse of light.

The second notable time was the night Mura Sanada went missing. His shadow hinted that Mura may have survivors guilt, and revealed a tortured Mura chained to a statue.
