Welcome to Shibasaki Vocational Academy...
"...One of the most prestigious and difficult-to-enter preparatory schools in Japan. The academy teaches only the top, 'Ultimate' students, but not only that — Shibasaki Vocational is a school for exclusively 'Twin-Talented' students, or those with two ultimate talents at once!
The new school year is about to start, and excitement is in the air…
…excitement for killing, as only through the murder of another student and the covering of the heinous act will a student earn their ‘graduation party’! After suddenly finding themselves trapped in a massive shopping mall, the fifteen bright young stars must face their peers with suspicion as unanswered questions hang in the air: Who will make it out under these horrific stipulations? Who will be used as a stepstool for someone else’s own selfish ends? And most importantly, who’s pulling all the strings…?”
