I just started thinking about this.
With Witch Hunter Robin, the relatively young age of all of the characters can kind of be dismissed because the STN-J is a somewhat fantastical organization, and it seems kind of implicit that the characters were recruited or something because of their talents. Also, the STN is affiliated with SOLOMON, which is affiliated with the Church, and while there seems to be formal training that people go through, it seems like they start them pretty young. So yeah, it seems odd at times that the characters are all so young, but not really too much.
With the Resident Evil series, some of the characters' ages aren't an issue. Barry Burton is relatively well cast at 36 years of age (or is it 38?), Claire Redfield at her initial age of 19 makes sense--she's a college student, so yeah.
But then it starts getting a little wacky.
Leon is listed as being 21 at the time of Resident Evil 2. Yeah, okay, I guess it would be possible for a really determined kid to bust ass through college and then a police academy program, but it's HIGHLY fucking unlikely. You do not meet very many 21-year-old police officers. Usually, at youngest, they're in their mid-twenties (23, 24, etc.).
Chris Redfield is listed as 25 years of age. This seems relatively unlikely for a man who is an EX AIR FORCE PILOT. This makes even less sense when one considers the fact that he was kicked out of the Air Force, drifted for a while, and then eventually joined up with STARS. This means he was maybe, what, 23 or 24 when he got kicked out? That's just not enough time to complete a pilot training program.
Jill Valentine is listed as 23 years of age. She's also listed as being an experienced Army Delta Force member. WTF. NOT POSSIBLE. Number one, that's Special Forces, a mostly combat-driven group. It's highly unlikely a woman would be a member of it, not to mention that it is once again something that takes years of military training. I highly doubt she popped out of her four-year run with the military at 22 or so already an elite Army Delta Force member.
Do not even get me started on Rebecca Chambers. NOT. EFFING. POSSIBLE.
Anyways. The point of all this?
When I write for WHR, the ages fit (especially in terms of the tension between Robin and Amon, wherein most of the tension lies in their age). The ages show how SOLOMON and the STN-J can take young people and turn them into Hunters capable of neutralizing witches through some Church-based training. When I write for Resident Evil, I automatically just assume everyone is older in the cases where their age seems implausible--I write Leon like he's 23 or 24 at the time of RE2, Chris and Jill like they're perhaps in their later twenties by the time of the first RE. (Chris and Jill I see as way more likely to be around 27, 28 or so.) This is completely not in line with canon, as characters reappear (and Leon is clearly stated to be 27 in 2004 at the time of RE4), but...damnit, it's just completely fucking implausible.
So. Keep in mind, if you read my Resident Evil stuff--especially the post-RE4 stuff, that I'm picturing that most of the characters (with the exceptions of Claire and Sherry, who had legitimate reasons to be young) are over 30 and in some cases, even over 40.
Japan has an obsession with young and vitality (I'm not kidding; look back at their history, especially the propaganda history from WWII). But in some cases, I think they're just being plain goofy with some shit.
