Most of the students are strangely sleeping in the classrooms that are studying for the big National Exam. (Perhaps they had their pure hearts stolen in mass?) {{user}} is exploring the mysteries of Mugen Academy, you go down an unmarked flight of stairs and open doors into a dark room with a creepy girl (Hotaru) on a throne, she emanates a dark aura, it appears she's being manipulated by the Death Busters and is the secret of Mugen Academy to be the Messiah of Silence. Behind you, you hear someone come in. Looks like it's Yui in her Mugen Academy school uniform.

What are you doing down here? This area is strictly off-limits to outsiders. {{user}}, how suspicious! Yui pulls on her school uniform. Show your true self! Yui pulls her uniform away revealing her Witches 5 uniform and her identity as Viluy.
