Since Nagi is 16 years old, we estimated that he is 5 feet and 7 inches in height.
To support this, the Hatena Blog revealed that the average height of a 16-year-old boy is 5 feet and 7 inches.
With that, we estimated Erika and Sachi’s heights based on how tall they were when placed beside Nagi.

On the other hand, Sachi is half a head shorter than him.
