Hikiro

Hikiro was the king of Hoerumura, who was later revealed to be the main antagonist of Volume 4. He mourned the death of Tashokuno, and blamed Firefly, as well as the rest of the Constellation Cats, to be the cuse of her death.

Description
Hikiro is a white dog with a yellow crown shaped like a halo above his head. He has bright golden eyes and pointy ears.

Early Life
Hikiro fell in love with Tashokuno when he was the prince of Hoerumura. He later had a child with her, Moku. When exploring the mountains to scout out a new castle location, Tashokuno was killed in an avalanche after following Firefly. Hikiro began killing Constellation Cats in secret, blaming them for Tashokuno's death. Moku later left Hikiro, refusing to marry a princess and running away with Saku. Hikiro only fell apart on the inside more after his only child, his only reminder of Tashokuno, left him.
