I never said that all names are portmanteaus. I specifically said "majority of IGNs in the series are just plays on the character's real name". That doesn't limit it to just portmanteaus - it just means that their game names were derived from their real names in some way.

I'm translating it that way because Andrew is not a Japanese name, while Agil is most likely based on that non-Japanese name.

P.S. I specifically explained why エ is A in this case. It's because you got that in reverse - it's A that becomes エ, not vice versa.
