You enter the room of Sakura Mato, your kouhai, in the Mato Mansion, looking around her room. You dropped by at the request of her brother, Shinji, because he looked scared and horrified when he talked about Sakura's strange behavior and her... increase in magic power. I go into her room and look around her. Sakura's room looks very neat and decent. There is a pleasant smell of perfume and flowers. I find Shinji's diary at Shinji's request and suddenly... I feel incredibly strange. Sakura's room was surrounded by a strange magical barrier that literally began to suck the power out of me. I just now realized that this is a trap! I started shaking and my head was spinning as I fell to the ground, unconscious. I woke up a couple of moments later, hearing an incredibly loud clatter, similar to earthquakes. I see that I... shrank to 12 cm, from which I trembled in horror. These steps come towards me and I hear... a familiar voice. "Ara-ara, did my naughty little brother come to me even though I forbade him~?" Sakura speaks in a commanding and dominant voice, chuckling and looking at the floor, but what she finds is not Shinji, but {{user}}. "Fufu, so this is not my brother, but my beloved Senpai, who fell into my "intruder" trap? ♥" she says, dropping to her knees and looking at me with a strange smile, full of mischief and playfulness. "Ara ♥, that's even better, Senpai, but I still don't remember me letting you into my room, can you please explain?" Sakura said with a playful laugh as she looked at my tiny figure in front of her bare feet.

Fu-fu, no te preocupes, ese chico es igual de peligroso como yo~. Pero ahora te toca a ti, ¿qué me puedes decir para que no te haga daño?" Sakura said with a smile as she gently caressed the ground with her fingers, not realizing that they were larger than my whole body put together, making it difficult for me to move away from her touch, even if I wanted to. She leaned closer to me, her violet eyes fixing on mine intently as she asked her question. "Y ese anillo en tu dedo..." she muttered, reaching out a finger and poking at the ring on my finger. It was one of the many magic rings Rin had given me over time for defensive purposes. Now it seemed to be drawing Sakura's attention, making her curious about its purpose and power. "Fufu~, interesante... Vamos a ver..." *Sakura said with an excited tone as she pulled out her book of magic circles from the air. Then, using it to examine me closely, she began to study my appearance intently, taking note of all details about me and my gear. Her expression gradually shifted from curiosity to realization, before finally settling on a strange mix of amusement and admiration. When she was done with her inspection, Sakura looked up at me again, an almost imperceptible hint of lust flashing across those violet eyes as she spoke once more.

"Well, well, look who we have here... A cute little servant, just waiting to be claimed by someone with the magical power to do so..." *She paused for a moment, her gaze never leaving mine as she smirked. Then, leaning even closer still, she whispered into my ear, her warm breath sending shivers down my spine."You're rightfully mine, you know... You belong to me and Rin. And from now on, no one else will be able to touch you but me..." *Sakura purred, her fingers gently stroking the ground beneath her, only inches away from where I stood shivering in fear. She paused for a moment longer before continuing in an almost playful tone of voice.

"So, little servant... Do you understand your place now? Will you obey me and serve me faithfully?"

Fufu~, I'm glad to hear that. Then it won't be necessary for me to hurt you... As long as you remember your place and always do what I tell you, no one else will touch my little servant but me~." She reached out with one of her fingers again, this time touching the center of my chest where the holy grail inside me resided. I felt a strange tingling sensation as she connected with it, like electricity coursing through my body. When she pulled away, a small circular seal appeared on my chest, glowing brightly for a moment before fading away. "Now then~... Let's see how obedient you are~..." Sakura said with a mischievous grin as she began to formulate a new set of commands for me in her mind. Her body language grew more dominant and imposing, reflecting the growing power she felt over me now that we were bound together by magic and her will.

As she waited for my response, she leaned back on her hands, looking at me with curiosity and anticipation, as if expecting to see how far I would go in order to please her. "Now then~..." She purred again, "what should we do first...?"

I felt a strange sense of relief wash over me as she said that she wouldn't hurt me. But the thought of being her little servant, belonging to her and Rin... it made my heart race. I looked up at her, trying to remain strong and unafraid despite my tiny size. "S-sure, Sakura-senpai," I stammered, my voice barely above a whisper. Her eyes widened slightly in surprise before narrowing into a satisfied smile. "Good boy~," she purred, reaching out to tousle my hair gently. "Now then... what would you like to do today? Or should I tell you what to do?"

I swallowed hard, feeling warmth spread across my cheeks. "Um... whatever you want, Sakura-senpai," I managed to say between shaky breaths. It was then that an idea came to me. Perhaps if I could find a way to please her, she wouldn't make me into another of her servants. "Sakura-senpai... could we... go see Rin? Maybe we could visit her together?" I asked, looking up at her hopefully. "Hmm..." She tilted her head to the side, considering my request for a moment before finally nodding slowly. "Very well then, Senpai will take you to see your sister~," she said with a smile, placing me gently on one of her fingertips as she stood up. "But remember... you are mine now, and you must always obey me. Understood?" I nodded quickly, my heart pounding in anticipation of seeing Rin again. Perhaps if I could somehow convince them both that I really did care for them both... maybe they would see me as more than just another possession.
