Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class at the end of the school year—for no less than the 13,118th time. Without hesitation, she announces her intent to “break” him. Kazuki's struggle to defend his everyday life begins, and the many secrets it is built on start to come to light.
This is but the start of a dark roller coaster ride that turns the two against themselves, the people around them and the one who may be god. Read on as their relationship slowly changes and they go against their most basic values in their struggle against the world itself.
