EXPLANATION OF LOVE AFTER WORLD DOMINATION CHARACTERS’ HEIGHTS
First, we determined Fudo’s height. On the Escape to Asia website, we have read that the average height for Japanese men is 172 centimeters or 5 feet and 8 inches.
However, we estimated that Fudo could be taller than the said height, considering his health-conscious lifestyle.
As for Desumi’s height, she appears to be a head shorter than Fudo when she is placed beside him.
Lastly, Professor Big Gelato appears almost to reach Fudo’s shoulders; hence, we estimated that he is 4 feet and 10 inches tall.
EXPLANATION OF LOVE AFTER WORLD DOMINATION CHARACTERS’ AGES
In chapter 7 of the manga, Desumi is revealed to be a 3rd-year high school student. According to K12 Academics, 3rd-year high school students are mostly 18-year-old.
With that, we based Desumi’s age to be 18.
Since Fudo appears to be in the same year, we assumed he is also 18 years old.
Lastly, based on Professor’s appearance, he could be in his 60s.
