From the campaign:
OVA: The Anime Role-Playing Game is exactly what it says in the title, a tabletop RPG lovingly crafted to capture the diverse worlds of Japanese animation. Save the princess (or prince!) from a fire-breathing dragon, tackle invading squadrons of giant robots, or find true love amid campus hijinks—everything you need is inside!
That's because when you create a character in OVA, you define what is important. You pick which attributes matter by choosing the abilities and weaknesses that match your character concept. There are no long lists of hard-coded statistics to fill out and no classes to sift through. If it's not important to your character, you don't write it down!
Character creation takes minutes, and the rules are quick, consistent, and easy to understand. This makes it perfect for novices and newcomers. But if you're an old hand at gaming, there's room for boundless customization. You could give your character a simple bonus to damage, or you can stick around and detail each and every flashy move with unique perks and flaws. Or you could eschew having any combat attributes at all. OVA lets you play the story you want to create, not a predefined notion of what an adventure should entail.
