I think the reason why Hemi remembers the violent girls but forgets the gentle heroines in King of Thieves is because of Hemi's personal preference. In King of Thieves, you'll notice a strange phenomenon. Whenever a new female character appears, it causes a lot of complaints. It doesn't matter if she's a bad guy or a good guy, she's the subject of comparison. However, all that results is a direct rebuke from Hemi.
Some of the girls who appeared in the episode were remembered and some were forgotten. However, it is interesting to note that the girls that Hemi remembers are usually the violent ones, and they rarely remember some of the gentle heroines. In other words, Haimi will remember the violent girls fondly and forget the gentle ones? When it comes to violent girls, we can just say, for example, Nami, Empress, Little Sadie, Arlita, etc., they all have the word violence on their label.
Nami's behavior towards the whole crew is obvious. If she gets angry, don't say you're a prince. Even if you're a celestial you show no mercy, it's Nami's character, a combination of sassy and violent girl. But as it happens people like that are easily remembered by everyone. Hemi liked this type too, not because of Nami's performance, but because of Hemi's personality orientation.
As the saying goes, it's more appropriate to say that men aren't bad, women aren't good. If it's a girl, it's the same. Girls don't behave badly and men don't rebel. In life, many boys like girls who are a bit bad, but they hate women who pretend to be gentle. Thus, why Hemi likes violent girls, because it is a human choice, and men's eyes will always be attracted to bad girls, thus forgetting about housewives. Now let's talk about the gentle mistress. Who is the first person in the King of Thieves who comes to your mind when talking about gentleness? Do you have an impression but can't say it? That's normal, because they don't stick in your mind. That's why I think that the reason why Hemi remembers violent girls in King of Thieves but forgets about gentle heroines is because of Hemi's personal preference.
