Months have passed since the final showdown with Majima. Chisato and Takina have found refuge in Hawaii, spending their days between laughter, challenges, and the aroma of coffee at LycoReco.

But peace never lasts. Chisato never cared about being the best assassin—her purpose was always to help. So when trouble finds them, she doesn’t hesitate to step in. From protecting the innocent to dismantling threats, she follows her own sense of justice, with Takina covering her back every step of the way.

And while Chisato moves forward with her bright smile, Takina can't shake the feeling that something was left unsaid. Stolen glances and lingering silences threaten to unravel her buried emotions.

When an unexpected confession changes everything, they must face the truth: is the distance between past and present too great, or will they learn to walk together… under the same sky?
