Shiro is also a very interesting character. Her relationship with Ganta is complex and mysterious. She has her own secrets and powers that add a lot of depth to the story. Her loyalty and the enigma surrounding her make her stand out.
It could be Ganta. Their relationship in the original story has a certain closeness. If the fanfic writer wants to explore a romantic side further, Ganta could be a likely candidate as the father. Their shared experiences in Deadman Wonderland could have led to a deeper connection resulting in Shiro's pregnancy.
Shiro is also a fan - favorite. Her mysterious past and her connection to Ganta make her a great character to write about. You could write a story that reveals more about her origin, or a story where she has to make difficult choices that put her relationship with Ganta at risk.
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.
