IS Vol. 9 (Light Novel)

In the near future, a new technology that threatens the stability of the world has been created. IS, or Infinite Stratos, are high-tech powered exoskeletons with technology and combat capabilities that make them vastly superior to any other arms on the planet. Seeing the devastating potential of the weapon, nations enacted the "Alaska Treaty" to make sure they are never used for warfare and to ensure that the technology is even distributed to all nations in order to keep the peace. However, because IS can only be operated by women, society takes a drastic change as women become the dominant sex.
Ichika Orimura is a 15 year old whose life drastically changes when he discovers that he is the first-ever male who can pilot an IS! Before long, he is thrown into the spotlight and forced to enroll in the Infinite Stratos Academy which trains students to become IS pilots. It’s not all bad, though – it is an all-female boarding school, after all! Now, together with his childhood friends Houki Shinonono and Lingyin Huang, he’s about to embark on a thrilling school life as the only male at the school as he sets out to prove that men can still be of worth!
In Vol. 9, Tatenashi is wounded in the battle against Phantom Task and Unnamed during the World Purge incident. And when Ichika swoops in to save her, she begins to have feelings for him. However, the other girls all vying for his affection won’t just sit back and let her get closer to him. It’s time for the girls to settle the score with a race!
