Definitely. Yakuza 6 serves as the finale for Kiryu's main storyline. However, the Yakuza franchise is known for its rich universe, and there's always a possibility of revisiting his character in some form or another.
No, the 1954 Godzilla movie was one of Godzilla's earliest works, but it was not the earliest. The name Godzilla first appeared in a Japanese manga of the same name in 1942. Before that, there were other forms of Godzilla's image, such as appearing in news reports, posters, and advertisements.
In a Zero Kiryu x Rido Kuran fanfic regarding unlikely encounters, the initial reaction between them would be very interesting. Zero, with his hatred for vampires (despite being one), would likely be hostile towards Rido. Rido, seeing Zero as an inferior at first, might underestimate him. However, as they interact more, they could find that they have more in common than they thought, like their determination in achieving their goals, which could lead to a change in their relationship dynamic.
One interesting aspect of a Zero Kiryu x Rido Kuran fanfic could be the character development. Zero might start off as completely opposed to Rido, but as the story progresses, he could come to understand some of Rido's motives, not necessarily agreeing with them, but seeing the deeper reasons behind his actions. Rido, on the other hand, could see in Zero a worthy adversary or even a potential tool for his own plans. This could lead to a complex web of relationships and plot twists in the fanfic.
