Rika Fuji, a user of Ice Breathing. She joined the Corps to slay demons. But with a cold heart, she had a frozen spirit. Nobody could break through her icy walls. And then she met Kyojuro Rengoku. She resented him and his flames. She wouldn't let him melt her icy heart. Rika would make it through the Corps and become an Ice Hashira. She would surpass this Rengoku. Sometimes life doesn't turn out how you want. Warning; this gets a bit spicy! This is mostly based on the events of Demon Slayer, but I have added my twist to it for fun. Thanks for reading.

There was nothing he could say to her. Because his friend was right, just like she usually was. They were young but the chances of them ever growing old were lower than just low. Maybe this would be the last time they'd see the sakura petals fall. Perhaps it was the last time he would see her alive. They were just 19 years old. Someone could say they were young, too young to die. "I guess we're not that young anymore, are we?" Inside, it felt like they were old. Nearly too old to be alive.

"Memories of our lives, of our works and our deeds will continue in others." Whether she was the light of their lives or not, they weren't sure. But they had to admit, she was absolutely stunning to make them feel such an intense amount of emotions despite being so young. Memories, [name] had tried to remember that dangling light she always sees when she was asleep or in a daze. But she couldn't remember the earlier events of her life. She had lost her memories, but deep inside there was this slight burning rage within her. Yet the smile remains on her face despite how dead her eyes looked.

Scars. Many had formed on the child's body as she listened to her family get ripped to shreds. The mountain whispered in the cold night, it told her to run and not to stop. It was the voice of her mother, even her older brother, and it echoed in her mind despite the growing pain of falling and getting thrown down multiple times. Demons. It was unbelievable. Well until she saw it with her own eyes. How? Why? Attacked. Her family was attacked by a demon. They told her to run. So she did. She ran and ran and ran. She was injured, but ran. So many questions filled her head, but she ran like her family told her too. Suddenly, a man saved her from another attack. It was fast and wielded fire with his blade. Who was he? A Demon Slayer. Why had he come? To save people from the beast, but she was the only one to save if he could save her from such injuries. She was younger than his son, but thought they'd get along well... so he killed the demon and quickly took the girl to one of his fellow peers, someone who could actually help. When she woke up... she saw a boy, a few years older than her. He seemed bright and caring, something new for the girl. What happens after that? What troubles will the girl face after that incident? Is there more to this than everyone believed? ________________________ I don't own the cover or the original story or plot. I do own my own plot and characters. Hope you enjoy!!
