Return to Tsukuyomi Island

Zero-Two lost her parents in the chaos of war and once lived in a care facility, later adopted by her master. To live again with his sister, he returned home after leaving the island four years later. The island combines natural scenery with urban facilities, but beneath the surface of campus life, conflicts among ability users exist.

A weapon in girlish form

Sakura, who saved Zero Two, is a strategic sabotage magic weapon numbered NO.13, acting in the form of a young girl. Zero-Two gains the ability to summon people he met within twenty-four hours and restore matter to the state he had seen for twenty-four hours. How to use these non-direct attacks became an important issue for him to protect his daily life.

Zero Two is the last awakened 'Summoner' No.13, while Sakura is the humanoid strategic destruction magic weapon he summoned. Sakura can think and fight independently, turning sunlight into magic. Zero-Two's recovery ability can recall people seen within twenty-four hours or restore substances to their state within twenty-four hours for support and repair.

Characters and subsequent versions

Huangshu Longyichi, also a war orphan, is an old friend of 02 and strongly desires to end the war, but his approach differs from 02. After the original, extended versions such as EXA and EXS were released; Their voices, additional plots, and age groups have all changed, so the specific version names should be retained.

Sayuki fires sound-recognizing magic bullets with her black-and-white dual guns, Momiji uses a long-range magic cannon, and uses the Seven Deadly Sins abilities and in-battle conversation strategies.

Family members and old acquaintances
