[@pkken]Is L Guardian's "Yoshida" his family name or given name? The reason I ask is cause they usually give the surname first (in most cases they even address others as surname-honorific but since most if not all of us are Western it doesn't matter much) and I didn't realize until just now that if it's his surname, he and Kenichi have the same family name. 

It wouldn't mean they're related, unless you wanted to do some backstory element with that (which could be neat, but up to you), cause I just pulled Kenichi's name out of the random generator on Behind the Name and Yoshida means something like "good rice paddy" or whatever and is one of the...I think top 20 at least most common surnames in the Japanese population.

Also what does the L stand for? XD
