Soukou Seiki Ysphere: Ingyaku no Sennou Kaizou 1

When the ruthless anti-human organization rises, Tia and Rina vow to protect humanity—but their unconventional strategy of overwhelming enemies with relentless pleasure leaves them both exhausted and intoxicated by the raw passion they unleash. As lust blurs into something deeper, the heroines struggle between duty and desire, their bond forged in battle now tested by the heat of shared ecstasy—and the fragile line between victory and surrender.
