Saiark

The monsters of the series, which are distinguished by their sunglasses and scarves. They are summoned when a commanders of the Phantom Empire traps an innocent human within a dark mirror, reflecting their happiness into darkness and suffering. When they are defeated, the trapped human is freed and their positive feelings are converted by a fairy into PreCards. Their name is derived from the Japanese word saiaku (最悪, "worst"). While most Saiarks possess scarfs reflecting the member of the Phantom Empire who summoned them, Red possesses his own personal legions of red-colored Saiarks.
