A child born with Purple hair pretending they arnt actually a Main character in some anime
Ugh, my mc doesn’t actually have purple hair, it’s a rather Angelic blond actually. Besides while the mc is the main character of the cog story here if it were an anime Astrid would probably be the mc. 
But considering the mc never would have found out their connections to the magical world and possible abilities on their own without Astrid’s ill-fated trip, Red-Shirt probably isn’t entirely inaccurate.
I like giving my MCs blue or violet eyes.
I like to think that my MC owns a neat little car, not too flashy/expensive but nice to look at, which he…borrowed at some point in his life.
Blue Eyes Master Race.
A seemingly average guy getting saved by a girl and introduced to a world of magic regardless of their wishes sounds pretty anime mc like to me 
I guess I don’t really watch much anime anymore these days. Anyway my mc looks way better than the average anime protag you’ve just described as from very quickly tvtroping it those seem to be almost always short and wimpy, very trusting and not too bright, whereas my mc is for the most part the opposite, tall, good-looking (keeping himself in good shape) clever enough, but more than that a bit mistrusting and very cunning.
But fair enough he used to be an “average” 'murican kid who was on the verge of deciding whether to sell his dignity or use his cunning, but risk his safety in order to garner that $100+ k a decent American college education seems to require these days.
He’s also neither in love nor in lust with said girl, which seems to defy the anime conventions where the protag is always invariably straight.
Grey/ Dark Silver eyes for me this time around.
Purple skin. Yellow eyes. No one will bat an eye.
Wouldn’t you just be stuffed into a genre at that point, with a good chance of it being porn? Unless you’re strictly going for shounen ai.
Look, I’m just a sucker for blue eyes.

OMG,
I’ve been reading this story for quite a while now, but this question just occurred to me;
Why is this story called Keeper of the Sun and Moon if it has nothing really to do with the sun or Moon at the very moment?
Just why?
Has this question ever occurred to anyone else around here?
Help me out.
Keepers are mentioned once or twice (one of Seraphina’s relatives was one), so it might just be their full title. As for why it’s in the game title, maybe the MC’s one. They do have special mind control powers.
Actually… someone did ask about this a few thousand posts ago XD
Echoing @daydreamsincolor’s answer then:
Nephilims and Cambions are likely related to this Sun and Moon.
This is probably pointing to the Artifacts but… 
I made a guess at what they are a while ago and the author answered. Sun and Moon = Dragons (gods) and Keeper = us from what I remember,. This is from a few… thousand post ago so my memory is hazy and the author may have changed it.
I mean, the sun and moon are most likely to be Nephilims and Cambions, (I would imagine that will be a war among them too since they hate each other) and the Keeper part, are probably us… probably.
Not true, at least not among the elite, though with the Africa story the mc can cover for one of their reports the political elite of both does seem to be intentionally stirring up some sectarian violence between their respective plebs for their own gain.
In our own school we already have the N/C pairings of Alty’s previous relationship with Cressy (and in my case his new one with my Nephilim mc) and his sister Astrid with Leon.
Well, that actually make some sense because Astrid is a Nephilim, and my MC is currently dating a Cambion. (Guess who.
Wink wink,
nudge nudge) That’s right, Leon. I’m pretty much the person that keeps them from killing each other.
They butt heads a lot, but they’ve gotten used to each other, even though they’re still not fond of the other person. Demons and Angels don’t really like each other that much, you know.It’s kind of hard for a Dragonborn to separate what is looked at as good, and the other as evil.
Dating Leon as a Cambion (I believe? It have been a long time since I play this) was probably the best route that I have done. He was cool with it (because it was brought up once and that was it.) Honestly, I think he made my MC love him even more then ever.
Wait… I thought Leon is the Nephilim and Astrid is the Cambion?
I honestly don’t remember which is which. I haven’t played this since the new update JUST came out. Legit. Even though this story is amazing, I’m too lazy to replay the entire story. But I thought it was the other way around. Wait a sec.
I goes and looks up facts of life
Urmm…
BOI YOU GOT IT…
HOO!
YOU’S RIGHT.
…
…Seriously, you’re right. I was wrong. Get over it.
It’s alright, we all make mistakes. ^v^
Actually, I don’t think that would be in character for the nephilims. An all out war between the cambions would be too obvious, too out there.
As we’ve already seen, the nephilim like to do their drity work in secret. They’d much rather prefer backstabbing some one behind the scenes than covering their tracks rather than declaring a full on war.
I have a question about Yakov.
If he invites you to hang out in chapter 7, is that his “date option” so far, or is there a “friend” version of it? Because so far, I haven’t seen any choices where the MC can blatantly show a potential interest in him, and I kind of wanted to check if I was on the right path. ^^
