The contrast between their characters is one reason. Ichika is the typical male lead who is learning and growing in the world of IS, while Tabane is this super - intelligent and somewhat mysterious inventor. Their interactions can be full of surprises.
The potential for unique storylines. Since Tabane has so much knowledge and power in the IS universe, she can bring Ichika into all kinds of situations. For example, she could take him to secret labs or introduce him to new technologies that no one else knows about. This creates a lot of opportunities for exciting and romantic plot developments.
One interesting fanfiction could be where Ichika discovers a hidden side of Tabane. Maybe she has a secret project related to the IS technology that only Ichika gets to be a part of. This could lead to a lot of adventure and some budding romance as they work together closely.
One great Ichika x Kanzashi fanfiction is 'A New Bond'. It focuses on their relationship development in a post - war scenario in the Infinite Stratos world. The story beautifully captures their growing understanding of each other.
In a fanfiction, Ichika and Houki could have a moment where they confess their feelings for each other. Maybe it starts with a simple misunderstanding. Houki sees Ichika with another girl and gets jealous. But then Ichika clarifies that he only has eyes for Houki, leading to a very sweet and heartwarming confession scene.
One possible fanfiction could be about Ichika and Chifuyu going on a training mission together. They face some unexpected challenges during the mission, which forces them to rely on each other more than ever. This could lead to a deeper understanding and bond between them.
The main appeal is the chance to introduce a new character. A male OC can bring new storylines and interactions. For example, he can have a different combat style compared to the existing characters in Infinite Stratos.
The appeal lies in the combination of two very different universes. Naruto has a world full of ninjas, with unique powers like jutsus, while Infinite Stratos has high - tech mecha suits. When these two are combined, it creates a whole new set of possibilities for stories. For instance, the clash between the ninja's stealth and the mecha's brute force can lead to exciting battle scenes.
An idea could be that Ichika and Houki are paired up for a special project at the academy. They have to design a new type of mech together. During the process, they argue about different design aspects but in the end, they come up with an amazing design. This experience makes them realize how well they work together and how much they care for each other.
One interesting plot could be a time - travel fanfiction. Ichika somehow gets sent back in time and meets a younger Chifuyu. They start to form a bond that is different from their relationship in the present. As Ichika tries to find his way back to his own time, he realizes how much Chifuyu means to him, and when he finally returns, their relationship has changed in a way that they both start to explore their romantic feelings for each other.
One of the best elements is the exploration of their different personalities. Ichika is often portrayed as the brave and somewhat clueless hero, while Kanzashi is more reserved and intelligent. Their interactions based on these traits can be really interesting.
Maybe Ichika runs away because he feels overwhelmed by the pressure at the academy. He might be tired of all the battles and rivalries.
