A café in Tokyo is a front for a covert agency staffed by teenage operatives, and the show works because it spends far more time on the café than the premise requires.
What the story actually is
Japan's public safety is maintained by DA, an organisation that recruits orphaned girls, trains them as agents called Lycoris, and deploys them under civilian cover. Chisato Nishikigi is the most capable operative in the programme and refuses to kill, using rubber rounds and relying on reflexes that border on precognitive.
Takina Inoue is transferred to Chisato's café posting as punishment for insubordination. The series is their partnership, the café's regulars, and gradually the question of what DA actually is and what was done to Chisato to make her what she is.
The slice-of-life is not filler
A large share of screen time goes to café operations, customer requests, shopping trips and cohabitation. Viewers expecting a tight action thriller sometimes read this as padding. It is not: the domestic material is what makes the late-season stakes land, because you have spent ten episodes in the place being threatened.
The Chisato and Takina dynamic is the centre and is written with a lot of care. Their partnership develops through competence rather than through declaration, and the show is confident enough to let episodes pass without plot advancement.
Production and action design
A-1 Pictures gives the action a distinctive character built around Chisato's non-lethal constraint, which forces choreography that is about evasion and disarmament rather than elimination. It is a real design decision rather than a stated rule, and the fights look different from the genre standard because of it.
The café itself is one of the better-realised anime settings of its year, with consistent geography and a warm palette that contrasts sharply with the mission sequences. The soundtrack leans on jazz and the show has a strong sense of place.
Who should watch it
Watch it if you want an action series with genuine downtime, a well-written central partnership, or an original story that is not adapting anything. It was one of the most-discussed shows of its season for good reason.
Skip it if the worldbuilding's plausibility matters to you. The premise does not survive close inspection and the show is not interested in defending it. The characters are the draw.
