At least that phantom pain no longer devours the snake.

This gives so much juice for an Isekai story. How Snake Inkling accidentally ended up in the world of Splatoon. There she befriends Captain Cuttlefish, the Squid sisters and the others. Things get good when a new enemy attacks and Snake, showing off his skills as the legendary soldier, finishes him off incredibly easily. Cuttlefish and the rest of her squad are impressed with her and propose that they help her return to her world, and in the meantime she agrees to join the Squidbeak squad to support them in defending civilians. Snake obviously finds this world very simple and somewhat innocent, especially because of its weapons, but he, or well, she, doesn't like that young people are used in wars here, she agrees to join and in the process will try to put an end to it definitive to the wars between Octarians and Inklings
