She, the prime minister’s daughter, was timid and cowardly. Because her engagement fell through, and her reputation was ruined, she was pressured to spill her own blood in the palace hall! Once again opening her eyes, the cowardice had vanished, replaced by coldness, causing others to be intimidated at first glance. Yet no one realized, she was not her.

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

A chance to change, to challenge destiny, making dreams a reality, and live a legend! A regular man gains a system that allows him to turn into a fish!
