Comment by dobrochell31 on Reincarnated into Demon King Evelogia's World - Chapter 22

He's an adult. He says somewhere later on that he stopped growing when he learned magic.

@dobrochell31  He's an adult

eve is definitely older than Gozo by atleast a few hundred years, but since he's a demon, he stopped growing. Slightly the same situation as hanako from tbhk

@dobrochell31 Eve is 18 ½ 😭 Gozo is 19
