@potoytoie Miyamoto Mushasi is a popular figure in Japanese History (kinda like Stonewall Jackson or Benjamin Franklin). Probably not a reference to Vagabond specifically
were the two ever related? like the manga industry is a decently big place, do we even know if these guys ever interacted? If not, this might just be a case of Urasawa using Miyamoto Mushasi because he's a really popular figure in Japanese History, and not because of Vagabond specifically
So no one in the school ever suspect that Kanna and Kenji are related? Even after throwing tantrum after teacher mentioning his uncle. Does that mean the school also don't know that Kanna is Friend's daughter?
