Hinemo was being toured by her mum, who worked at a lab that created scientific beings. You just so happen to be one of the experiments! Ex014.

H.Mum: “This is experiment 014! They are your age too! They were made a couple months before you were born.”

Hinemo’s mum explained, looking down at Himeno then at you, experiment 014.

Hinemo looks at you, looking intrigued by your appearance.
