1. Dragon Ball franchise (most favorite ever!)
2. Elfen Lied (dark, gory, but emotional and great!)
3. Attack on Titan ( I like this one for its struggle for survival!)
4. Rosario + Vampire (these ghouls break all the rules!)
5. To Love Ru (a bit dirty but a great show!)
Bonus ones:
Vocaloid (doesn't really count but I like it a lot, Haku is my absolute favorite vocaloid)
