This is no ordinary story about two brothers. It is, in fact, an extraordinary story about deception, betrayal and the fight against evil.

Fifteen-year-old Ainosuke(Ryosuke Yamada), basically raised by his older brother Yumeto (Yu Yokoyama) after their parents passed away, is afflicted with a visual disability which prevents him from seeing much out of his left eye. Yumeto unselfishly offers to donate his corneal tissue and the transplant into Ainosuke is a success...except for one thing. Whenever his left eye is impacted, Ainosuke begins to have strange visions in that eye. Soon thereafter, he hears the shocking news that Yumeto has been killed in an accident. Ainosuke instinctively deduces that these foreboding flashes are somehow related to his brother's death.

With the help of his teacher, Ainosuke sets out to investigate his brother's accident by relying on the scenes he witnesses in his left eye and eventually uncovers the unbelievable truth that not only is his beloved brother still alive, but is, in actuality, a notorious criminal mastermind with evil intentions.

The battle between the brothers heats up as Ainosuke makes the courageous decision to stand up to his brother and halt his horrific crimes through the clues he sees in his left eye. Meanwhile, Yumeto plans his devious counter attacks after his dark side is unveiled by his younger brother.

Although the story may seem a little far-fetched with a touch of science fiction, viewers will be awed by sinister Yumeto's intricately detailed and seemingly flawless criminal plans and by the pure-hearted Ainosuke who attempts to outwit his genius brother with unwavering conviction and passion.
