I'm not entirely sure specifically what 'oboro visual novel' is about as there could be many with that name. It might be a story - perhaps a fantasy one, or it could be centered around character relationships and their growth.
One common theme is friendship. Since Naruto is known for his ability to befriend others, in fanfics with Oboro, their friendship often takes center stage. It could be about how they support each other through tough times.
Shigaraki is not dead in the manga. The storyline has many twists and turns, and his character plays a significant role, so his survival adds to the ongoing drama and suspense.
One great plot twist could be that Shigaraki has a hidden noble intention behind his actions. Maybe he's trying to expose a deeper corruption in the hero society that no one else sees. It makes readers re - evaluate his character.
In niles x oboro fanfiction, the theme of cultural exchange can be quite prevalent. Niles and Oboro come from distinct cultures, and writers may use this as a backdrop to explore how their cultures interact through their relationship. This could involve things like sharing traditions, language barriers, and different values. Another common theme is the idea of redemption or growth. Maybe one character has a past they're not proud of, and through their relationship with the other, they find a way to become a better person.
One common theme is loyalty. Fans often write about how Oboro and Niles are loyal to each other in their relationship. Another is adventure. They might be on a journey together and their relationship grows during that time.
In a great 'Shigaraki fanfic', the plot is crucial. It should be engaging and original. Maybe it could put Shigaraki in new and unexpected situations. It also should have good pacing, not too slow or too fast. And the relationships he has with other characters in the fic should be well - developed, whether they are allies or enemies.
Isolation is another theme. Shigaraki is often depicted as a lonely figure. Fanfics may explore how his isolation affects his actions and decisions, and how relationships (or lack thereof) shape his character in the BNHA context.
