I have no clear knowledge of when Jubei will be released in Central Fiction. Maybe you can search in gaming forums or follow the game's social media accounts to get the latest on this.
No, it's not a true story. It's likely fictionalized or based on some historical elements but with creative liberties taken for entertainment purposes.
Sure, Blue Eye Samurai is a manga. It stands out for its creative world-building and the depth of its narrative. Many fans appreciate its combination of action and drama.
The story of The Seven Samurai is somewhat original. It combines various themes and character archetypes in a fresh way, although it may draw inspiration from common storytelling tropes.
