And for the record this type of top 5's are the ones I've literally fallen for I have different top 5s for everything I guess...

1. Blue Moon
2. Lightning Stone
3. White Edge (Yes but before Blue he was no. 1)
4. Asymmetric L (Or was it Asymmetry?)
5. Kagamine Len/Append (default... Well if you don't consider him as a module then its Append)

Aaaaaaaand that's my top 5 for the ones I've heavily fallen for. Remember this is MY top 5. Okay! Enjoy? Enjoy!
