Ok I've been looking into Anima for some time but no one plays it at a local gamestore that I usually go. Is there any place in Riverside, California that has people playing it? Another thing, what supplies do I need for the game?

Many people on these forums have had to order the book (for the RPG) from online sites. You will need at least 2d10, paper, pencil and a calculator might be helpful depending on your comfort level with percentages. But the character sheet allows for plenty of "cheat" space for number the pcs will use and besides being able to photocopy the combat chart (for personal use and pc quick reference) that's about it! Hope you find some more players.

I took some time to read the book (or at least glanced through it) and I saw stuff that needs d100s, can you clarify this to me please?

Roll 2 d10's and read the two numbers like it's really one number. Like if one die shows 3 and the other 7, the result of the roll would be 37. You can use different dice for the 10s and the 1s, but I just read left to right.
