I have way too many interests to think of any off the top of my head. If I had to really say I had any supreme interests, it'd probably be these few things:
1. Saber
2. Kurumi
3. Adorable lolis, even though I'm not a lolicon.
4. Visual Novels
5. Anime
6. Pizza
7. Food (Yes pizza is above food)
8. Working out
9. Women.
10. Being a dick (I'm an asshole, playfully)
