I'm not entirely sure as I haven't read it in detail. But generally, it might be about Guren Ichinose facing some sort of catastrophe when he is 16 years old. It could involve his struggles, growth, and how he deals with the challenges that come with this catastrophic event.
The character of Ichinose Natsumi herself makes these visual novels special. Her unique personality traits, like her kindness and determination, are often central to the story. This makes her a very relatable and engaging character for the players.
For a 'sunahara wataru sakura fanfic' to be good, it needs to stay true to the spirit of the original while also being creative. It should respect the personalities of the characters. For instance, if Sunahara is known for his humor in the original, the fanfic should incorporate that in a natural way. Additionally, the fanfic should have a clear theme or message, whether it's about friendship, love, or something else, and convey it effectively through the story.
Since I don't know which new novel it is exactly, I'm not sure if there are reviews out there yet. It might be too early for reviews if it was just released.
Since the title focuses on Guren Ichinose, he is definitely a main character. There might be other characters like his friends or comrades who are also important. Maybe there are characters who are antagonists in the story, who create the catastrophe or oppose Guren during this difficult time. However, without reading the novel, it's hard to name all of them precisely.
I'm not sure specifically which 'sunahara wataru sakura fanfic' are popular. You could try searching on fanfic platforms like Archive of Our Own. They usually have a wide range of fan - made stories about various characters and topics.
Wataru Watari often takes common themes in youth - related stories, like friendship and love, and twists them in unexpected ways. He doesn't follow the typical formulas. Instead, he presents characters who have their own flaws and insecurities, and through their experiences, readers can gain new perspectives on these familiar themes. His light novels are a refreshing take on the genre.
In my opinion, it is worth reading. The world - building in the novel is quite fascinating. It expands on the universe of 'Owari no Seraph' in ways that the anime might not fully cover. You get to understand the complex relationships between the characters better, and the writing style is engaging enough to keep you interested throughout.
