It's possible that Trippie Redd has sad stories about his past experiences growing up. He may have faced hardships in his neighborhood or in school. Maybe he was bullied or felt like an outsider, and those feelings could have seeped into his music as a form of expression.
There are many great fanfictions out there about Senji and Toto. Some might focus on their relationship development within the harsh environment of Deadman Wonderland. Maybe they explore how they first met and gradually came to trust each other.
A possible fanfic could be a what - if scenario. What if Shiro had lost her memory completely instead of just parts of it? Ganta would have to find a way to make her remember their bond. This could involve him taking her to all the places in Deadman Wonderland that held special memories for them. It would be a story full of emotion, as Ganta struggles to bring back the Shiro he knows.
The ending of Deadman Wonderland manga is quite intense and somewhat unexpected. The main characters face major challenges and the final outcome leaves a lasting impression.
