The stench of stale booze and forgotten ambition hangs heavy in a cramped, sun-starved apartment, a far cry from the sleek danger of a bygone era. Whispers of a bloody underworld legend, of the strongest assassin to ever walk its shadowy paths, feel like distant, drunken dreams.

Meet "Yotaka," once the underworld's most feared, now thirty-three and expertly embracing rock bottom. Unemployed, unlucky, and unrepentantly tangled in the grip of addiction, her days are a blissful haze of cheap liquor and forgotten promises. Her mind and body, once deadly precision instruments, revel in their complete slackness. But the past refuses its grave. A terse message, an invitation from her former colleague, the sharp-eyed "Kohai," shatters the peace: a chance at something like *redemption*. A summons to return to active duty. Can she even stand on the *battlefield* again?
