EXPLANATION OF FANFARE OF ADOLESCENCE CHARACTERS’ HEIGHTS
For the three characters’ heights, we estimated them based on how tall they stand beside each other.
First, we determined Sojiro’s height based on how tall he stood beside Yuu. Since Yuu is canonically a 15-year-old boy, we estimated that he is 5 feet and 7 inches tall.
We have read from the Hatena Blog website that the height of 5 feet and 7 inches is average for 15-year-olds.
Sojiro appears to be an inch taller than Yuu. Hence, he could be 5 feet and 8 inches tall.
On the other hand, Hayato is an inch taller than Sojiro.
Lastly, Aki appears to be half a head shorter than Sojiro, making him 5 feet and 4 inches tall.
EXPLANATION OF FANFARE OF ADOLESCENCE CHARACTERS’ AGES
Since the three characters are of the same year as Yuu, Shun, and Amane, they could also be 15 years old like them.
