Há seis meses, Hikaru desapareceu por uma semana. Agora, desconfiado de que algo esteja errado, Yoshiki, seu melhor amigo, o confronta e descobre a verdade atormentadora.

A powerful witch can cast spells without speaking; in reality she is just shy and distant from people. But now she is assigned to guard a prince.

Two years ago, the death of Naoto Watari's parents left him as the sole caretaker for his younger sister Suzushiro "Suzu" Watari and forced him to move in with their aunt. So devoted is he to Suzu that he refuses to join clubs or even hang out with anyone, earning him snide comments and the title of "siscon" at his new school. But as long as Suzu is safe and happy, Naoto doesn't care what everyone else says. However, his sneering classmates may turn out to be the least of his worries. The sudden transfer of a girl named Satsuki Tachibana brings back traumatic memories from his past-a past she had a hand in making so unpleasant. Nasty secrets, unknown to Naoto, begin to surface with her arrival, threatening his new life.

Cursed as a child to never have an heir, Prince Oscar seeks the continent's most powerful witch, Tinasha, hoping she'll break his curse. To meet her, he'll have to climb her formidable tower, which grants a wish to whoever reaches the top.
