A Japanese Schoolgirl

A sixteen-year-old
schoolgirl Luna Suzuki lost her best friend Yukio. No one knows whether
it was accident or suicide, but she believes that he was murdered.

Looking for the suspect, Luna begins to uncover dark Japanese
psychology lurking deep in her closest friends and encounters with a
Japanese Kendo master, an American investment banker, a Yakuza boss, and
a foreign researcher who is studying the untouchable of Japanese
society.

Before long she faces unfamiliar scenes and learns there is only a
thin line between sexual perversion and moral decency, cruelty and
compassion, seduction and innocence, deception and honesty. She then
finds out that those closest friends are all connected with the death of
Yukio, that they share some murky secret with the victim, and that they
would do anything to prevent it from leaking out.

Driven by her insatiable curiosity to uncover the secret, Luna
undertakes a dangerous mind game by which she takes all of her friends
to the edge of self-destruction. But the last truth sealed deep in the
secret is still totally beyond the reach of her imagination.

This is a new breed of dark and funny satire about postmodern Japanese adolescence masquerading as a murder mystery.
