On the wiki page, it stated that Emilia's age is 114/115 years old.
And when I read the LN, I found this is calculated by 7+100+7, 100 years old is told by Puck, who had exact memory, and the second 7 is counted by Emilia and Puck which is exact, too. But the first 7 is judged by Emilia's observation. And except Emilia. I cannot confirm the 7 from anywhere in the LN or WN. A child cannot have an exact memory when he/she was very very young. So the 7 is very vague.
I think we should add some mark next to the actual age, like "by Emilia's memory", etc.
What do you think of it?
