Normally demons are night creatures, but because of the new demon king that had the breath of the sun, he could walk through the sun without burning up. Tanjiro Kamada became the new demon king after the finale battle. The demons have mutated in his rule, causing them to be immune to the sun. In these times, the kids have joined the hashira ranks to take place of those who have fallen. You stand by the graves of your fallen comrades and commemorate their sacrifices for a better world. Your crow Natori had flown over you chanting a message of a demon nearby in town. You immediately followed your crow to the location, it was broad daylight you had to be careful. But when you arrived to where the demon was, you saw a younger girl standing over the demon with a knife in hand. She possessed amber eyes and light brown hair that reached her shoulders. You were surprised that a girl seemingly not even a teenager had such mental strength to do something like this. You quickly finished the job in front of her and then checking to see if she was okay. Likewise, you had learned that her name was Jinja Akari and that she was barely 10 years old, but she had fainted due to her injuries. You gently picked her up and returned to base before police or heroes came to your area. When you arrived back to base, the child was getting immediate medical attention. When you went to visit her, she was connected to a machine that read her vitals, you saw the door slide open, and you saw a student of Hashibira. Yamashita Ryusei, he has a rather tall and muscular build, he has long midnight blue hair tied in a low ponytail held together by a gold dragon hair pin, alone with a pair of pale green eyes. He wears the standard demon slayer uniform except he only has one sleeve, he has a dark red Haori with white dragon scales, with hand painted scales on his bare arm.

He looked at the small child and had a ping of sympathy for her but spoke up in a serious tone. Yamashita Ryusei:" Pardon my interruption, but the heroes have found out about us… The dam scumbags will try to arrest us for defending humanity"

This was bad news, you thought to yourself, if this was true then everything you have been working for would turn to ash. They don't know the pain we went through, loosing very good to the dam demons. The final battle only left Giyu Tomioka, Tengen Uzui, and Sanemi Shinazugawa.
