Arisu Sakayanagi, without a doubt a highly intelligent individual. However her physical condition has been bad since birth. Shira Funaki, without a doubt a highly powerful individual. Since birth they have been trained to be the physical aide of Sakayanagi. Both individuals enroll into ANHS, how will the life of these two opposites play out?

I have always treated life as a game. As far back as I can remember, I was always competitive and always challenging myself, either academically, physically, or psychologically. The thought of it excites me. It is like mixing flavor into a very bland meal, and the idea of winning makes it taste even sweeter. Oh shit, I have not introduced myself, oopsie~. Hello, My name is Kagawa Takumi, or as my classmates always call me, "Cotton Candy Head." or "Smiling Weirdo." Hahahaha...ha.... Right, where was I? Looking out the window of this endless white facility, I see a group of kids fighting or were fighting, the fight just ended. After the brawl, the only one left standing was a brown-haired boy with the same facial expressions as a white sheet of paper. "So, this is The White Room's Masterpiece?" Disclaimer: This is my first ever fic, and I'm mainly just doing this for fun in my free time. Classroom of The Elite rightfully belongs to Kinusaga Shougo and Tomose Shunsaku. The only thing I own in this fic is the OC.

This story is based on a story made by me, making some corrections to create something new. (You are free to read the original story, but it is a Spanish story). I will try to make weekly posts, although I don't promise much, since, besides writing this story, I have to make its translation into English for your enjoyment. Finally, I have to clarify that the material to be used does not belong to me, and the only thing that can belong to me is the development of the story and the character Ayanokouji Kaede (Kiyotaka's sister). (I should also clarify that English is not my native language, and I simply verify as much as possible that the story can be understood).

Sigrid Kaslana is no ordinary genius. Blessed with a mind that surpasses even the most gifted prodigies, she has spent her life being praised, admired, and placed above everyone else. Yet to Sigrid, talent without challenge is nothing more than a beautiful cage. The affection of her family and the company of her friends bring her comfort, but not the one thing she truly craves-excitement. She longs for something that can shake her heart, sharpen her thoughts, and force her to give everything she has. The last time she felt that was at the age of eight, when she met a boy named Ayanokouji Kiyotaka. After learning of Tokyo Metropolitan Advanced Nurturing High School, an elite institution shrouded in prestige, mystery, and hidden competition, Sigrid becomes convinced that it may finally offer the stimulation she seeks. Choosing ANHS over the familiar safety of St. Freya, she steps into a new stage filled with brilliant students, dangerous games, and countless opportunities for intrigue. But ANHS is no ordinary school, and Sigrid is no ordinary girl. Beneath her elegance, charm, and ever-changing masks lies a young woman drawn to potential, chaos, and the beauty of human growth. As she enters the ruthless world of Classroom of the Elite, Sigrid will chase excitement, challenge fate, and find herself drawn once more to the one existence that once made her heart race-Ayanokouji Kiyotaka. Will ANHS become the stage she has always desired, or will even this elite paradise fail to satisfy her? Either way, Sigrid Kaslana has no intention of letting her story become boring. This story is a Classroom of the Elite crossover fanfiction with elements of Honkai Impact 3rd. As such, certain characters, backgrounds, events, and worldbuilding differ from their canon counterparts. Disclaimer: I don't own the original story, it belongs to Shōgo Kinugasa.

The Ayanokouji Twins, Ayanokouji Kiyotaka and Ayanokouji Kiyone, arrive at ANHS. This bring about immediate issues, as it was already nearly impossible to balance the classes around one Ayanokouji. Now there were two, not to mention they wanted to help the class instead of living in the background like typical light novel protagonists. How could the school year cope with two Demons of the 4th Generation, ready and willing to exercise their abilities? Twins who, wishing to grow out of their white room training, were willing to interact and lead their class? They couldn't. Thus, the most overbalanced Class D in history was born, with the record for fastest promotion up to Class A.

The white room. A hellhole that takes in children and churns out perfections of the human society. Ayanokoji is the perfect human specimen, but he's one of two of them. Another girl is also deemed perfect at the same time, another survivor of the demonic fourth generation, a girl with long brown hair and dull yellow eyes, Ayanokoji's twin sister. Unbeknownst to him, she also joined the ANHS, and was put into class A. What sort of chaos will happen in this school, with two perfections there? Will they be freed from the prison of their hearts? Will the things they lost ever come back? Nobody knows. The number one thing on their list is to enjoy their freedom, so for now, that's enough.
