Apeas

Apis (アピス, Apisu) is one of the Four Heavenly Kings in the kingdom, known as "King's Spear". He is a spearman who faithfully follows the orders of the king.

Appearance
Apis is a very tall man with a long face, prominent nose, and small grey eyes. He typically wears a silver-white breastplate over khaki garments with a fur-trimmed neck, black knee-high boots, and a dark green half-cape with a red collar.

Personality
Apis is the most enigmatic member of the Four Heavenly Kings. Like Bebin he appears to have started as a Bosse Kingdom guardsman who was later elevated to a Heavenly King, but the circumstances surrounding this are highly mysterious.

What is known is that Apis is almost fanatically loyal to King Bosse himself, and treats his monarch's word as law. He is one of two council members to choose Bojji as Bosse's successor, seemingly solely because Bosse decided so in his will.

However, Apis does not seem to have any particular loyalty to any other member of Bosse's family, or the Bosse Kingdom itself, and initially quit his role as a Heavenly King after Daida's ascension to the throne.

Apis is one of the few characters (apart from King Bosse and Drushi) who is acquainted with the mysterious Lady Miranjo. She came to like Apis while he was still a guardsman, and helped train him into a Heavenly King. Miranjo believes Apis is highly sensitive and easily hurt, and because of this he understands the pain of others.

Now that Miranjo's plots have come to fruition, Apis finds himself deeply-conflicted. He is torn between his loyalty to his king and his benefactor, and his loyalty to the friends and colleagues he's made in the Bosse Kingdom.

Master Spearman
Apis is one of the Four Heavenly Kings of the Bosse Kingdom, a role that's akin to being a senior officer, general, and bodyguard all in one. Apis specifically was designated as the, "King's Spear," meaning he most closely served King Bosse himself. He was specially-selected for his personality, and specially-trained by Miranjo to be an exceptional spear-user.

Trivia
