Basically this quote by Eddie. The problem with the pure pretty-boy line-up is a major down-turn for the majority of male and a portion of female viewers. That isn't to say that it isn't warranted at all, but I'll get to that. I'm going to use Hololive as my example scenario because I know them better; but I will add that these personalities are showcased in both Holostars and certain Niji male talent. But there are specific Western (American) twists to them; they also need to be much less polite. I have some anime equivalents that might help round out the idea. . . send the autistic flags.
Catering to fujos is the only point against watching them, for me (hopefully the fujobait won't be as common in the NijiEN boys as it seems in my initial impressions though). To be fair, I can't stand too much GFE either.
I said it before, but the way to make the Male EN work is to primarily cater it to Male viewers and make them a good, diverse, team. Personally, I'd only do three and the personalities should hit a certain core dynamic. You need a semi-self-containted group of personalities that act as a real foil to the primary HoloLIVE talent. This will more than likely incur the wrath of the idiotic gachikoi, but but down the road will prove useful in propping up JP Holostars as well. En can get away with it, supported by that fanbase.
So unto the talents. here is our big three:
1. My personal favorite,
our asshole. Think Mikoshiba from Nozaki-Kun. This guy needs to be the gachikoi's big-bad that thankfully can't deliver. He's crass, curses more than most talent, treats his subs like friends he is bringing to the bar. The best gamer of the bunch. essentially a male Selen. Probably sings country, but in the vein of 26 by Chris Stapelton. The hook, and it is a gamble, would be that he seems like the flirtatious fuckboy. . . unil he starts talking. Have Suisei or some of the more killer talent just flat out rip into him till he crumbles. He's the cool dude you thought you wanted to be to get with a HL talent, but he is even worse off than you. . .
2. An actual fucking white knight. Probably gay or close to it; the only real fujo-bait. The caveat is that you need someone that is self-aware enough to not be a crazed 'sexuality is my identity' moron. You want the gay dude that's funny, and calls flamboyants faggots behind closed doors. Polite though, and generally nice and positive. Hopefully the most artistically talented, but maybe can hit some contralto. This is the pretty boy that actually successfully hits on the HL talent without a care in the world, while actively and for obvious trolling reasons does the same for Number One above. To which the response isn't a Takamori bait, but a comical, 'you outplayed my words you fuck' goddamnit. Decidedly no real relationship, but if you build it, the fujis will come.
3. The Ice-man. The anime, strat, and JRPG connoisseur. You need to find that guy that exudes a feeling of being 'over it.' He'll play the straight man to the other two's comedy dynamic. This guy needs the wit, and absolutely no filter in burning his gen-mates. The HL talent think he's cool and mysterious. He isn't, just has a heart-rate of 27 and a blood temperature in the negatives. This is our 'I'm Sakamoto.' Best case scenario he can shred on the guitar or pull out some badass instrumental talent.
And look right there, Maverick, Goose, and Ice-Man. The key to victory. It is self-contained, can work in any three man multi-player gamespace with easy fan integration in 4-man, or six-man teams (or dare I say it, a guest HL/HLS collab). Each member is quarantined from being competition to the parasocials by their very nature, and the team aspect can reinforce that if necessary by ranking on eachother.
Fujoshi crap will come no matter what. Playing into it will just cut out another aspect of the market. AmeSame is much more palatable and sellable than Takamori ever was; and it derived from a more natural and fun back and forth. . . not by playing to hard into that stereotype.
And, if played right, this kind of dynamic could lead to greater interaction between JP Male and Female talent. But. . . that might be a pipe-dream. And all of this would take Cover or any Japanese corpo thinking like a sleazy Madison Avenue Adman. . . and we can only hope for that.
