As much as I love the Blood Moon series, Jhin doesn't fit in this category.
Blood Moon as been associated with the ninjas and blades, the reason the skin works with Kalista and Thresh, is because of their actual demon/spirit background. Jhin is too mechanical with his weaponry to be considered in the Blood Moon series. Unless they give him a legendary skin where his weapons are built into his body, it doesn't fit.
And to be entirely honest, I don't know why Elise is in the series. I don't play her and haven't read her lore, but I'm sure it has something to do with her turning into a spider or something.
Maybe Headhunter Jhin more. But good job on this piece nonetheless. Hopefully my my comment doesn't bring you down. Keep up the good work.
