Sequel of Himitsu.
A prequel to Himitsu
that follows Maki Tsuyoshi and his best friend Suzuki Katsushiro during
their college days. The year is 2045, when MRI technology was still in
its nascent stages.
A decade ago Maki's parents were killed in a
fire, and since then he's been living with his legal guardian Sawamura
Satoshi, who suffered severe burns while rescuing him. Though he's
convinced that his parents were murdered, Maki has no clues to help him
find the culprits other than the hazy memory of a certain symbol.
Upon
discovering that this symbol is associated with a powerful secret
society called Premium that's based in Tokyo University, Maki enters the
same college, hoping his top credentials will get him an invitation to
Premium. He isn't chosen, but the more socially adept Suzuki is. Maki
approaches Suzuki in hopes that he'll lend him his aid, and the two
embark on a hunt for the truth.
