Hitomi, a Pokémon ranger, achieves her objectives by collaborating with untamed Pokémon instead of capturing them. Instead of using Pokéballs, rangers employ a slider tool to interact with these creatures. After completing her training, Hitomi partners with a proficient ranger who possesses an exclusive Vatonage slider - a tool reserved for elite rangers. Hitomi is curious about the capabilities of this exceptional ranger and the functioning of the Vatonage slider.
