Check if there's official merchandise or events that combine these elements. Also, note that some content might be NSFW, so the guide should mention that. Maybe include tips on where to find such content, like fan sites, official stores, or events.
Putting this together, the user probably wants a guide that includes cat-related content within the Milky Holmes universe, focusing on Mari and Hoshizawa, perhaps involving the DMC22 fan club, and "extreme" and "Gokkun" might relate to specific merchandise or events, like a more explicit or intense version of the characters.
Starting with "milky," maybe they're referring to the anime "Milky Holmes." The "cat" could be a reference to cat-themed elements or characters. Then "dmc22" might be a fan club or a specific group name. "Mari" and "Hoshizawa" might be characters from the Milky Holmes series. "Extreme" and "Gokkun" are a bit trickier. "Gokkun" could be a nickname for someone or another character.
