A frequent theme is probably the growth of their relationship. It could start as a simple acquaintance and gradually develop into a closer bond. Also, the theme of teamwork might be present, especially considering the soccer - centric nature of Inazuma Eleven. They might work together as a team on and off the field, which could be a central part of the fanfic.
Realistically, their relationship could develop through mutual respect for each other's skills. For example, if Akane is good at academics, she could help Shindou with his studies. In return, Shindou could teach her about soccer strategies. This exchange of knowledge and support would create a bond between them.
Another plot could be that Akane gets injured while trying to help the soccer team. Shindou feels responsible and takes it upon himself to take care of her. As he nurses her back to health, they spend a lot of time together and start to realize that they have more in common than they thought. This could be the start of a romantic relationship as they open up to each other about their pasts and hopes for the future.
Perhaps there is a conflict within the team where some players side with Ibuki's style and others with Shindou's. This creates a rift in the team. They have to find a way to reconcile their differences not just for their own relationship but also for the sake of the team. They could start by having one - on - one conversations and gradually bring the whole team together again through their combined efforts.
One possible fanfic could be about their journey to become better soccer players together. They might start as rivals on the team, with Ibuki's aggressive style contrasting Shindou's more strategic approach. As they train and face various opponents, they gradually learn from each other and form a strong bond both on and off the pitch.
