Lukio: “Hurry, Lune! We have to warn all the animals!”
I always thought Lune and Lukio (or Runi and Ruki, if you prefer) in the 1966 Leo the Lion series were so much like their parents it’d be Helheim telling them apart when they were older, so I wanted to give their designs a little more personality. Now Lukio is easily distinguished from Lyra by her ear markings and spiky, Kimba-esque hair. And Lune, even without his little yellow scarf, can be told apart from Leo by his brown eyes and rounded, puffy, Kitty-esque hair.
