Darkrai Mission Story: Pokémon Ranger Vatonage - The Comic summary:

Hitomi is a Pokemon Ranger; someone who uses wild Pokémon to achieve their goals rather than capturing them. While Pokémon Rangers don't need Poké Balls to capture Pokémon, they do use a tool called a Capture Styler in order to form a bond of friendship with the wild Pokémon. Two years after Hitomi's graduation from the Ranger School, she joins a team with a Top Ranger. This Ranger uses a rare type of styler called a Vatonage Styler, which is only available to Top Rangers. Just what kind of skills does this Top Ranger have, and more importantly, how exactly does the Vatonage Styler work?-Mangaupdates
