Under the Dog

Hana enters an Enoshima high school under orders from Flowers, a covert organization that uses young operatives as expendable weapons. Her mission centers on student Shunichi Nanase, but she is not the only one seeking him.

The arrival of another visitor and an armed assault turn the school into a battlefield. With the operation collapsing, Flowers deploys Anthea, while Hana struggles to carry out her assignment under a system that punishes failure far beyond the individual agent.
