The Grafting Covenant, in other words, is Rox's promise to graft the life of a living cherry tree, and for the cherry tree to graft his swordsmanship onto his offspring.

　Rose then began to wrap up her story.

As I just showed you, we of the Valencia clan are born with the mark of the cherry blossom on our left chest, the mark of grafting. That is proof that the covenant is still in effect. And in fact, I have had the memory of Sakuraga Itto-ryu since before I can remember.

"Is that so?

Oh. In other words, the Sakuraga Itto-ryu is not something you learn from someone else. It's something that we, the Valencia clan, can recreate using Rox's memories.

　That's how she answered the first question I threw at her.

I see. ......

　Rox Valencia, the founder of the Sakuraga Itto Ryu.

　He lives for two thousand years and encounters a rare living cherry tree on a deserted island in the middle of the ocean.
　The island was destined to sink with the cherry blossoms to the bottom of the sea due to the erosion of the waves.
　Mr. Rocks, who regretted this, took in the living cherry blossom as his spiritual nucleus, and the cherry blossom was grafted with the memory of Sakuraga Itto-ryu to his descendants as a lodging rent.

　This is the bond that continues to this day, and it seems that the Valencia family is relying on the memories of the founder to "recreate" the Sakuraga Itto Ryu.

　I thought I was just going out for a quick swing, but I ended up hearing an incredibly grand story.
