Yeah, I was thinking of painting in broad strokes to prevent any canon puncturing or confusion, but it was one of those "Wait, I KNOW this history period, and odds are the character would too since she's from a modern environment."

Given that it's Rival Schools the history teacher can probably chuck textbooks as projectile attacks, but that's neither here nor there. (And there IS a swordsman in the canon, though Akira doesn't necessarily have the highest opinion of him. Thankfully it's more with the character himself rather than the fighting style.)
