Calgurio/Relationships

Minitz

 * Minitz is Calgurio's right-hand man. The two are good colleagues and friends.

Gradim

 * They are fellow commanders of their respective divisions and well acquainted with each other.

Gadra

 * Calgurio respects him for his past achievements, but thinks his head is stuck in the past and claims his ways are outdated. He finds Gadra's warnings to refrain from challenging Veldora ridiculous and even derides him, calling him a coward.

Yuuki Kagurazaka

 * Calgurio finds him to be an annoying upstart and "green behind the ears."

Rimuru Tempest

 * He originally underestimated Rimuru and led an army into the capital of Tempest. After being informed by Misha that the decoy army was annihilated, he couldn't believe it at first; he was then told by Krishna that the Dungeon invasion army was also destroyed. He attempted to surrender with conditions but that failed. He was confronted by Diablo and his soul was reaped. When he awoke he saw Rimuru as well as his comrades whom he thought to be deceased. Rimuru resurrected 700,000 of the invading army including Calgurio in a weaker state. This led them to view Rimuru as a god.
