Or it's Hera's dad who either:
A - think Hera's into girls given her recent 'closeness' with Dew and her keeping distance from the prince
B - think Hera shouldn't associate with 'lesser being'
C - is harming Dew as indirect threat to make Hera 'stick to the script' of trying to get with the...
The problem is that only keep her 'quiet', and in some way that's the WORST state to leave her in.
It's good for keeping her still for a short time, but that's all.
Just recall how many things she just do 'on the side' that become the sort of things to get put under classified secret stuffs...
Might I remind you this is all essentially flashbacks?
Considering what present day Bega is doing it was obvious she didn't get the actual answers she wanted.
This is mainly meant to be the villain origin story for Bega.
So again you're the one who got yourself into some high expectations then...
I'm aware of that, it's the other guy who can't seem to take the elves saying essentially 'we don't know, we don't care, DEUS VULT Infidels' as 'cop out'.
So you should be saying that to him.
Y'see, unlike Japanese where things like katakana exist, Chinese doesn't have separate letters for foreign words so when they have to deal with foreign name they just try to find characters with close enough sounds and slap them together.
So instead of Jolene, it's Qiao Lin.
No no, she need to blush profusely to make the dad get even more pissed and make some kind of ultimatum that'll come back to bite him in the ass after Hesha and Jolene decide to support Irene for the gayvolution.
It also mentions he's their first child in the line after, so unless THAT also got cut off there's literally 2 things in the RAW pointing to him being the only son.
What source might this be? Because if it's still that same group that did part one then they're just trashy MTL that just happen...
Literally in the same damn paragraph where Minako got first mentioned:
二句之家長男である美王子ハンサムは、歳を取ってからの初めての子供でテンションが上がりまくった両親によって命名された。
"Nikuno family's ELDEST SON Handsome"
The excalibur part is actually saying because his mom's friend named their own child with kirakira name, Handsome might be...
It's the same kanji as their initial plan of Venus, but thanks to the nurse convincing them, the registered furigana is Minako.
Also Excalibur is son of the mom's friend, so not his brother.
You're taking/expecting it as explanation, but I see it as just adding more layers to the mystery of things and not at all meant to explain the upgrade stuffs.
It's not a cop out if it's not meant to even be an actual explanation to begin with.
