The protagonist's grandfather decides to bring Specter inside in order to study him. The grandfather then attempts to recreate this beings powers. The protagonist then gains the ability to transform into a being known as Brightboy or Brightgirl (depending on the gender chosen.)

The newly powered up protagonist then decides to help Specter battle the Gyala Gang.
