The opposite is loneliness
At eight years old, leopard horses begin to lose sight and hearing of all animals, including those around them. But he could see the darkness, and the darkness was transparent to others. Their meeting allowed Leopard Horse to rebuild their lives and made the two sides, once separated by the world, a link between each other and everyday life.
The Black in the Five Worlds
The five closed worlds in the story are called Calamity Worlds. Differences in childhood experiences have led to different personalities for Black from different worlds: Fuu has leadership, Kina values intelligence, Mi tends to act, Natsu is free and sharp, and Nyu is more peaceful. They are not five unrelated girls, but the different growth outcomes of the same character in a parallel world.
