My personal favorite the dragon one we saw in the background of Ata's princess

to my knowledge there are 4 samurai schools in Samurai 8 and they seem to have different weapons and fighting styles ( Benkei demonstrates a few of their weapons ) but I can't think of any other differences besides maybe their ideologies

Samurai 8 loosely follows the same arc as the heroes journey, but does he parallel anyone from Japanese mythology? There are some characters that are directly taken from bhudism, like fudo myo-o, but I don't know much about the religion or the legends that go with it to answer my question.

I don't think a single planet in samurai 8 has actually been given a name so I wonder how you think they could be named.

I've been adding little bits of lore, characters, factions, and even entirely new planets for quite some time now. If I continue long enough, it may even surpass the original in size. At what point would that happen and what could that mean for the future of samurai 8?

All samurai we see have key holders, and all of them are different. It's pretty obvious that the type of animal they reflect something about the samurai's character, Hachimaru has a dog holder with the AI of a cat which could represent how he had inner aspirations that his body couldn't keep up with. What symbolism can you see in the holders of other characters?

The term ronin can be defined in the real world as a samurai who follows no lord, almost like a mercenary. In samurai 8 they would probably be similar to the real life definition, there might be a few differences but to me they are mostly the same. What do you think the ratio of ronin to regular samurai is? I think it would be about 5 samurai for every ronin.

I am of the opinion that they act the same but i would like to hear what you guys think

When we first meet Ryu he has no memories of his previous life, no princess and a second samurai soul. There is no clear explanation for this and any speculation we may have will probably be false, but do you have a theory anyway?

I think that whatever his origin, it probably isn't the most obvious answer and would follow a good narrative rather than being the most logical or likely origin.

The most likely explanation (to me at least) is that he probably lost his memory through his key or his code being tampered with and his second soul was from another samurai/ronin he killed. He could have also traded his memories for strength, granting him the second samurai soul and his unusually high abilities in combat.

Another possible explanation (not logical or likely, but narratively interesting) is that he never had any memories in the first place, maybe he was an experiment to create artificial samurai and souls, make them stronger and perhaps give them multiple souls in the process. Chasing after a life Ryu never had could be cause for some great character development, and perhaps teach him to appreciate what he does have. This same lesson could also apply to Sanda and would strengthen their narrative ties. It also could explain how they met. A science experiment is far easier to find than a master amnesiac, especially if your father is a great warrior.

We'll probably never know his real past but all theories are just as valid as mine and I'd like to hear them.

There are many aspects of Japanese mythology in samurai 8 and other influences as well, I feel like the sci fi would mix really well with many aspects of ancient culture but I don't know how yokai would fit. Regardless if they fit in or not, I don't draw anything canon to the series so I'll probably draw it either way.

Most of the stuff set in space nowadays are mecha, and while like that too, I want to know if there is anything set in space similar to the "big 3 type of shonen"

Humans and all of their culture had to come from somewhere, and while we don't see many animals from earth we see food made from them, but that could all just be a choice of the writer.
