The QED Club has become the go-to place of students and teachers in Clark High whenever they have mind-boggling mysteries and perplexing puzzles they want solved. For months, club president Loki Mendez has been managing it alone, but circumstances will force him to open its doors to new members:

A female transferee from Manila who’s trying to cut off her past and start anew.

A theater actress with excellent memory who’s willing to step out of the spotlight just to join the club.

A male transferee with superb deduction prowess and formidable hand-to-hand combat skills.

They are not heroes, but whenever the school is in trouble, the QED Club will always be there to save the day.
