All of these openings and endings are a great example of how different BLEACH is. The score to the show gives that in the first few minutes but these themes blend the comedy and lightheartedness (Asterisk and Tonight, Houkiboshi) with how heavy the show can be (After Dark, Velonica).
Asterisk - Orange Range
Tonight, Tonight, Tonight - The Beat Crusaders
After Dark - Asian Kung-Fu Generation
Velonica - Aqua Timez
Houkiboshi - Youhna (has all the different versions)
