Infinite Stratos: Volume 9

The battle against Phantom Task and Unnamed during the World Purge incident didn't just leave Tatenashi wounded—when Ichika swooped in to save her life, it melted her heart, too. (What do I do? I'm falling for him...) But she's not the only one after our hero, as the rest of the crew won't be content to sit back and watch as they grow closer. With Field Day coming up, it's the kind of race for his affection that could only happen at IS Academy! All's fair in love and war in the ninth installment of this high-speed school battle romantic comedy!
