As the second princess, Yukiko seemed to fully support her older sister. Arthur could even feel her sincerity.
It's actually quite an amazing case because sometimes sibling relationships among noble children aren't so great behind the scenes.
The jealousy of the second daughter towards the first daughter is common.
Although most of them didn't commit hostilities, it was only because they suppressed their jealousy.
Unfortunately, it is always there.
Yukiko on the other hand, it was as if she wanted to escort her sister to the highest position in this world.
But after thinking about it, Arthur thought that this might be a habit of the Japanese Imperial Family, which was also the reason why they could last so long.
Yukiko for example is still the original descendant of the First Emperor of Japan who started the empire thousands of years ago.
The family with the most Emperors is definitely that family.
Even in the Sky World, it's hard to find one like that.
