The Rotten Fruit on the Rotten Tree, You and Me Beneath the Rotten Tree

"What?"

Rin Tohsaka was clearly stunned when she heard that. "You mean... you want me to give Archer to you?"

"Big Sister, not Archer."

Sakura Matou shook her head, then said with unwavering determination, "He is my savior."

As part of a magus's body, Magic Circuits were theoretically much like breasts or thighs. With her body this small... her Magic Circuits probably hadn't fully developed either.

At that thought, Sakura Matou unconsciously clenched her
