"Can you protect them all?"

With police patrolling up and down, emergency alerts ringing out on cell phones, and anxious adults whispering rumours, a disturbing atmosphere hangs over the town. Amidst this tension, Hiroshi, Kyoko, and Mitsuki encounter a masked man wearing a red cape. He asks them if they prefer red, white or blue, but their innocent answers could have horrifying consequences.
