Dragon Quest IV・V・VI：About the character's bloodline

The "Zenith series" consists of Dragon quest Ⅳ, Ⅴ, and Ⅵ.
In the previous video, I explained the connections between the stories of the "Zenith series", but this time I will explain the connections between the characters that appear in each work.
Although much of the content this time is "Unofficial Information", it is still interesting, so I hope you enjoy it.
