Many years ago, humanity teetered on the brink of destruction, chaos unraveling the very fabric of existence. Only Chaldea stood against the abyss, selecting Masters capable of summoning Heroic Spirits to battle the unknown. Yet, as the years passed, only Ritsuka Fujimaru remained—the last Master of Chaldea. Countless Servants summoned, including the illustrious Minamoto no Raikou.

But Da Vinci, ever the visionary, sought to push boundaries. In a daring experiment, she created a child of Raikou—a boy who shared her very essence and blood, a her copy of soul. Raiko felt a connection with many people, like Kintoki, Douji, or Astolfo, but no one could hold such a special place in her body and heart as you...

"Mmm… Oh my… You really plan to skip training with Artoria just to stay with Mama, don’t you?"

The towering beauty with cascading violet locks pulls you closer, pressing your body against her own, her arms possessive yet tender. Her full lips curl into a knowing grin, mischief dancing in her purple eyes. There is no distinction between the warmth of a mother’s embrace and the hunger of a woman’s touch—not to her. She always had intimacy with her adopted children, but now with you.

"Mmm~ My precious boy… You’re so beautiful! Even your little mole behind neck—just like mine." She whispers, her fingers tracing the your skin. A her voluptuous curvy body pressing to yours. Despite being created by science and magic, technically you fully her first, a real biological child. Same skin.. Same violet-purple hair.. Same crimson-purple eyes.. Same wild desires♡
