Yes, it is. 'Deadman Wonderland' combines elements of science fiction such as advanced and often dystopian technological settings. The prison-like amusement park where the story is set has various high - tech devices and systems that are not of the ordinary world. For example, the collars the prisoners wear which can be used for both control and monitoring are very much a science - fiction concept.
I think a great Senji x Toto fanfic could involve their adventures within Deadman Wonderland. Maybe they team up to face a new and powerful enemy in the prison. Senji's tough - guy attitude and Toto's unique abilities could make for an interesting dynamic. Writers might also delve into their backstories and how they influence their relationship in the fanfic.
One possible fanfic could be about Shiro and Ganta's adventures in the cruel world of Deadman Wonderland. It might focus on how they rely on each other for survival. Shiro's unique personality and her relationship with Ganta can be explored deeply. For example, it could start with them facing a new and dangerous game in the prison - like arena, and how they use their individual strengths to overcome the challenges together.
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.
