He has a spike on both of his shoulders (They rip through his shirt), a smaller one on his back (Barely rip through his shirt) and he has spikes on the back of his hands. The funny thing is most people think it's cosplay, but he doesn't even know what that means! He looks 10 but he's actually 13. He normally wears all blue. He has grey eyes and grey hair that BOTH match the spikes on his body. Arai's name actually comes from the word array. It's even pronounced the same way.
