Some references you'll need.

Here's some facts for the coming chapters. I researched everything and found a few details I needed.

Oden was executed at the age of 39, 20 years before the present.

He returns to Wano at the age of 34, if my calculations are right.

He's 59 (deceased) post timeskip canon. And post timeskip canon Yami will be 28.

So Yami is born when Oden is 31, he's 3 when Oden returns to Wano. During Oden's execution, Yami is 8.

After coming back to Wano, Oden clashed with Kaido, when he attempted to get rid of Orochi's oppressive rule.

At this time, Oden was asked by Orochi to dance around naked on the streets of Wano, and this is where 3 year old Yami first meets him. Well, sees him I guess.

So yeah. Sorry if you were expecting a chapter, I really need some time to think stuff. The next chapter will be out by Saturday night.

Hope this was helpful!
