One possible plot could be that the Inkling girl gets lost in the human world. The human male finds her and at first is startled but then decides to help her. They start to communicate through gestures and simple words. As they spend time together, they discover each other's unique cultures. For example, the Inkling girl shows the male how to do Inkling - style dances, and the male teaches her about human technology.
Another theme is adventure. They often go on adventures together, exploring new areas of the Splatoon world or trying to solve a big problem. This could be something like finding a lost relic or stopping a new threat to their world. In these adventures, their relationship grows as they rely on each other.
The relationship can start with curiosity. The Inkling girl could be curious about the human male's appearance and his different way of living. The male could be intrigued by her unique Inkling abilities. They can then start to interact more, like sharing their favorite things. For example, the Inkling girl shows him her favorite Inkling games, and the male shows her his collection of human books. This sharing helps build a bond.
One popular Splatoon Inkling x Octoling fanfic is 'Under the Ink Sea'. It has an interesting plot where an Inkling and an Octoling have to team up to solve a mystery in the world of Splatoon. The story does a great job of developing their relationship from initial distrust to mutual respect and friendship.
One possible plot could be that the Inkling girl accidentally gets teleported to the human world. The human male, being curious and kind - hearted, helps her adapt. They start to communicate through gestures and drawings at first. As time passes, they discover common interests like their love for art, which in the Splatoon world is expressed through their unique ink - based creations and in the human world through paintings and sculptures. They then team up to create a joint art project that combines elements from both of their worlds, and during this process, they develop a deep friendship that could potentially turn into a romantic relationship.
In a story, the relationship can be developed through shared experiences. For instance, they could both participate in a competition. The Inkling girl might use her ink - based skills and the human male his own unique talents. Through the ups and downs of the competition, they support each other. After the competition, they realize how much they enjoy each other's company. They can also have adventures together. Maybe they go on a journey to find a missing item that is important in both their worlds. Along the way, they face challenges, overcome obstacles, and in the process, their relationship evolves from strangers to friends and perhaps more.
One common theme is the idea of 'forbidden love'. Since Inklings and Octarians have been enemies in the Splatoon lore, their relationship in fanfiction often involves breaking the barriers of this long - standing hostility. Another theme is cultural exchange. Writers might explore how an Inkling and an Octarian learn about each other's cultures while falling in love. For example, an Inkling might learn about Octarian music or art, and vice versa.
A common theme is the idea of forbidden love. Since Inklings and Octarians are often in a sort of rivalry in the Splatoon universe, their love is seen as something that goes against the norm. Another theme could be acceptance, as they learn to accept each other's differences, be it in appearance, culture or way of life.
One common theme is the overcoming of differences. In Splatoon, there are inklings and octolings, and often in love fanfictions, they have to overcome their cultural and species differences to be together. For example, in many stories, an inkling and an octoling might face prejudice from their respective communities but still choose to love each other.
I'm not sure about a specific one off the top of my head. But often, these fanfictions explore themes like acceptance. For example, an octarian who was once an enemy in a game - like scenario, but then through a series of events, like getting lost in a strange world together with an inkling, they start to rely on each other and that turns into love.
