One possible story could be that Otonashi and Kanade are in a garden filled with lemon trees. They share a sweet moment as they pick lemons together, and the scent of the lemons in the air enhances their connection. They start reminiscing about their past experiences and how their relationship has grown, all while surrounded by the fresh, citrusy aroma.
A simple plot could be that Otonashi finds a lemon - scented handkerchief that belonged to Kanade. He starts to think about her every time he smells the lemon on it. Eventually, he returns it to her, and they have a heartfelt conversation about how something as simple as a lemon - scented item can hold so many emotions and memories for them.
Well, in the Kanade Tachibana visual novel, she could be special due to her relationships with other characters. Her interactions, whether they are friendships or something more complex like a romantic interest, play a big role in making her unique. For example, the way she communicates and how she grows and changes throughout the story because of these relationships is really interesting.
There could be a fanfiction where Tsukushi and Tsukasa are expecting a child. It might explore how they prepare for the new arrival. For example, they could be shown shopping for baby clothes and setting up a nursery. The story could also delve into their emotions, like Tsukushi's excitement and Tsukasa's nervousness about becoming parents.
One popular theme is the exploration of their pasts. Since both Otonashi and Kanade have mysterious pasts in the anime, fanfictions often delve deeper into what might have happened before they arrived in the after - life world. Another theme is their relationship development, as mentioned before, whether it's romantic or platonic. Also, the theme of redemption can be present. They might help each other find redemption for things they regret in their past lives.
The relationship between Otonashi and Kanade in fanfictions can be quite diverse. Some fanfictions may focus on a romantic relationship between them. Otonashi's leadership qualities and his caring nature towards Kanade can be the starting point of their love story. On the other hand, some may explore their relationship in a more platonic way, like how they support each other in the after - life world of Angel Beats. They both have their own traumas and pasts, and through their interactions, they help each other heal.
Perhaps the way it's written. If it has a great narrative flow, beautiful descriptions, and engaging dialogue, all these elements combined can make the 'kanade mayo chiki light novel' special.
One idea could be a 'what - if' scenario where Kanade and Otonashi meet in a different world than the afterlife setting of Angel Beats. Maybe they are in a modern - day high school, and their memories of the afterlife are just hazy dreams. They start off as strangers but gradually feel a strange connection.
