I'm not sure what's funnier, imagining the hammer be solid and the sound effect being "Bonk!", or it being more of a plastic toy mallet that squeaks and crumples / uncrumples whenever it hits something.
Why is it that whenever a manga ends with an unclear harem ending, especially when there's a major love declaration being interrupted by the rest of said harem, I hear the Love Hina theme play in my head?
