"My friend said that Lucky Star makes references to a certain anime, and that I should definitely watch it. But I can't remember what the name of it was, could you help me out? D:>"
Oh dear! Lucky Star makes a whole lot of references to a bunch of anime!
I guess the biggie would have to be The Melancholy of Haruhi Suzumiya.
If that doesn’t ring a bell, Lucky Star also makes major references to:
- Fullmetal Alchemist
- Full Metal Panic!
- Code Geass
- Sergeant Frog/Keroro
- Gundam
Hopefully this helps! I’m only able to list a little, but there’s a whole lot more references that are very small.
