Synopsis
Protect the earth from giant creatures with humanoid weapons. In those days, I, Yuka Nagamori, met a "girl". robot. The girl introduced herself so. According to a doctor-like man by her side, she is named "Choco". Choco said he chose me as a "friend."

"Tomoka, I'll ask you one. What are your friends?"

You don't know. ...... No, wait. Then do I know what that means? In a sense, it's more unrealistic than a giant robot. A machine with the most beautiful eyes of any human being. This was my encounter with chocolate.
