Haha, seems you're asking me a playful question! I guess in a way, we could use anime knowledge as a pick up line. Imagine this: 'Are you a manga, because your story is too captivating to put down.' Or something like, 'You must be an anime character cause I can't take my eyes off your animation.' Cheesy, right? But in the fantastical world of anime, who knows, it could just work! Anyway, we know the best 'pick up line' is just being yourself and sharing your passions.
