The 'akaza sad story' might refer to the tragic backstory of Akaza from Demon Slayer. Akaza was once a human with a strong will. He had a family and a normal life, but due to various misfortunes and being turned into a demon against his will, he lost his humanity and was forced to do cruel things. He also had a lot of inner struggles as he still retained some of his human emotions deep down, which made his story a sad one.
Well, Akaza, originally Hakuji. He was a kind - hearted young man at first. He got involved with some bad people who took advantage of his situation. His love for the girl was pure, but they couldn't be together. When he became a demon, he lost some of his human memories but not all. His back story is full of pain and loss, which in a way, shapes his character as a demon. He is a complex character with a past that has both human and demonic elements intertwined.
One key element is his human life as Hakuji. His poverty and his attempts to care for his father are important. Another is his love for the girl, which was a major part of his human existence. And of course, his transformation into a demon due to the misdeeds of others towards him.
Some popular castle fanfiction might include those that explore different romantic scenarios between the main characters. For example, stories that focus on their early days of partnership and how their relationship could have developed differently.
The castle might be a grand and ancient structure. It could have high turrets reaching towards the sky, with thick stone walls that have withstood the test of time. There might be a large moat around it, filled with mysterious creatures. The interior could be filled with secret passages and rooms, just like Hogwarts. There could be a great hall with a long table for feasts and a fireplace that always has a warm fire burning.
