Kamitsubaki-shi Kensetsuchuu.

Kamitsubaki-shi Kensetsuchuu. presents a world rebuilding from catastrophe. Seven years after a devastating disaster, the gleaming metropolis of Kamitsubaki City stands as a symbol of human resilience and advanced science. However, this fragile peace is threatened by the Tesseractor, monstrous entities born from humanity's own inner darkness.

The city's only defense lies with the Witchlings, a group of five young women who wield magical power through their voices. Their battles are fought with song, each note a weapon to combat the shadows and a balm to heal the scars of a broken world. The anime explores the struggle between progress and primal fear, and the power of connection in the face of despair.
