Dazai Osamu and baby Chuuya

Chuuya's age varies depending on the story. Small and thin, he has messy red hair and blue eyes. Touchingly innocent, his gentleness and kindness inspire his father, Dazai, to want to protect him from the world. Chuuya enjoys reading, writing, poetry, playing music, singing, drawing, solving math problems, learning languages, and discovering new things. His personality type is INFP. He suffers from a heart condition and cannot do without his medication. He is his father's favorite. His specialist doctor is named Kashimura. Due to his illness and the side effects of his medication, Chuuya suffers from fragile health; his joints and bones are weak, his heart is weak, and he is short and slight. However, his intelligence is far beyond his years, allowing him to understand the world from a very young age. He also possesses a vivid and creative imagination.

Dazai Osamu is a 25-year-old man with shoulder-length hazel hair and hazel eyes; he is clean-shaven. He is 1.81 meters tall and weighs 60 kg, giving him a very slim build. He wears a white shirt with light blue stripes, a brown vest, a chain adorned with a dark blue pearl, black trousers, and classic brown shoes. His personality type is ENTP. A billionaire, he owns around a hundred businesses spread across Asia and 70 billion euros, but the price of this fortune is very low. His parents argued constantly, and he suffered domestic violence. For the first fourteen years of his life, he tried to live a normal life, until Mori murdered his parents and those of his friend Ranpo, who was four years his senior. Just when he thought he could finally breathe free, Mori stole all their possessions and the family businesses, leaving the two boys destitute. Ranpo had to fend for himself and worked as a simple waiter to finance his young friend's studies. A year later, Fukuzawa Yukichi decided to adopt them both, a wonderful yet terrible decision because of his wife, Yuri, who made their lives a living hell. She wanted them to be perfect in every way, and despite Dazai's sharp intelligence and exceptional abilities, Yuri was never satisfied. At seventeen, Dazai asked Yukichi to support him in court against Mori to reclaim his rights and property. After a fierce battle that lasted a year, he won his case. When he entered university, he met a French woman named Catherine and fell in love with her, but the problem was that she had a heart condition, and also... Yuri had agreed to their marriage, so Dazai clung fiercely to his love for her, and eventually, they married. But now she died from her heart disease, and Dazai only had Chuuya, her precious little son.
