Well, in fanfic, an Inkling Girl is often a creative interpretation. Since Inkling are those cool, squid - like characters from Splatoon. Writers of fanfic might give the Inkling Girl her own personality traits that could be different from what we see in the game. For example, she could be more shy or more adventurous, and the fanfic could revolve around how she deals with the challenges in the Inkling - centered world, like turf wars or making new friends.
First, create interesting characters. Give the Inkling Boy and Inkling Girl unique personalities. For example, the boy could be a bit of a daredevil while the girl is really smart. Then, start with an exciting situation like they are in the middle of a big ink battle. Build their relationship gradually, through small conversations and shared experiences. Also, add some humor. Maybe the Inkling Boy makes a silly mistake during a mission and the Inkling Girl teases him about it.
Adventure is also a big theme. The Inkling girl and boy might go on an exciting journey together, exploring new areas in the Splatoon universe, and their relationship grows stronger during these adventures. They could be facing challenges like new types of enemies or difficult terrains, and they rely on each other to get through it, which deepens their bond.
Some common themes could be friendship. They might start as friends in the fanfic, having adventures together in their inkling world. Another theme could be competition. Since inklings are often into battles in the game, they could be rivals in the fanfic at first and then develop feelings for each other. Also, discovery of new places in their world can be a theme, as they explore together and their relationship grows during these explorations.
