Weed and Rigel from Ginga Densetsu Weed: Orion.
I wish we'd gotten to see Weed spend more time with his puppies. I really like these two. I think Rigel would've been the best option as the new leader (but Weed had literally no reason to step down so young so idk why he did, maybe he's just tired)
Cherry blossoms with Weed is an obvious choice and I was gonna add another flower to represent Rigel but then I looked up Japanese flower language and cherry blossoms mean "kind, gentle, transience of life" and I felt like those all fit Rigel well enough too.
