Hugo

Hugo is a character in Eternal Senia. He is a mage from the village of Nuothe who meets Senia while they are both working on the same request. He joins her in her mission to rescue Magaleta after being persuaded. He has a brother named Hugh who is cursed. Later it is revealed that he is actually a warlock, which makes him a target of the Sanctum who hunt warlocks.
He can cast ice magic, but is also a hunter of his own kind who is aware of the danger of being exposed as a warlock. Hugo is also a spirited but with a heart of gold, and he often acts cold to others. He sacrifices himself to prevent Medea from advancing, and ultimately disappears into the unknown due to the growing suspicion that he is a warlock.
