Title: She Became Existence... In the bustling halls of Sakura High School, there was a girl named Akari who always seemed to fade into the background, unnoticed by her peers. No one knew much about her except that she was quiet and kept to herself. But one day, everything changed. It started with a rumor spreading like wildfire that Akari had made a deal with the devil to become someone else - someone more confident, more assertive, more... present. Whispers filled the air, questioning who this new Akari was and what had happened to the old one. As days passed, Akari indeed seemed different. She walked with her head held high, spoke up in class, and even joined the drama club. The once invisible girl was now taking center stage, dazzling everyone with her newfound charisma. But as Akari's popularity soared, strange things began to occur. Students who had crossed her path suddenly found themselves facing misfortune - failed exams, broken relationships, mysterious accidents. Rumors swirled once again, this time questioning if Akari's transformation had come at a dark price. Amidst the whirlwind of gossip and suspicion, only one person remained steadfast by Akari's side - Yuki, her childhood friend. Yuki had noticed the subtle changes in Akari long before anyone else, but chose to believe in her unwaveringly. As tension reached its peak and the truth behind Akari's transformation was finally revealed, Yuki found himself standing between his friend and a menacing force from beyond. In a heart-wrenching climax, Yuki had to make a choice - to let Akari succumb to the darkness that had consumed her or to fight for her soul, no matter the cost. In the end, as the final curtain fell, Akari and Yuki's bond was tested in the ultimate battle of light against shadow, with the fate of their intertwined destinies hanging in the balance. And as the last echoes of their struggle faded away, a single question remained - had Akari truly become someone else, or had she simply found the strength to be who she had always been?
