Description
Mikleo is a seraph aligned with the element of water, and he serves as the deuteragonist of the story. He was originally born human in the village of Camlann to a woman named Muse, but through her prayers he was reborn as a seraph and raised in the seraph capital of Elysia alongside his childhood friend Sorey. As a seraph, he is normally invisible to most humans, though those with a high enough resonance can perceive him. His true name is Luzrov Rulay, meaning Mikleo the Enforcer.

In terms of personality, Mikleo is calm, collected, and level-headed, often acting as a grounding presence for Sorey's more impulsive and idealistic nature. He is thoughtful and reserved in his speech, but he is also quick-witted and occasionally sarcastic, and he can become flustered when teased. He has a strong sense of loyalty and dedication, especially toward Sorey, and is not afraid to offer frank advice or challenge Sorey's decisions when he disagrees. His insistence on looking at matters from an archaeological perspective frequently leads to friendly arguments between the two.

Mikleo's primary motivation is to support Sorey and to pursue the dream they shared since childhood: to uncover the truth of the world and find a way for humans and seraphim to coexist. He accompanies Sorey on his journey as his closest confidant and, eventually, as his Sub Lord. He is deeply concerned about Sorey's well-being and wrestles with feelings of inadequacy, wanting to be strong enough to stand by his friend without being a burden. After witnessing the deaths and tragedies tied to the Shepherd's fate, his determination to find a correct path only strengthens.

His most important relationship is with Sorey, who is his best friend, brother figure, and rival. They have known each other since before they could walk and share an unbreakable bond. Mikleo also develops a connection with Alisha Diphda, the first human he meets besides Sorey, and he later supports Rose as a comrade for Sorey, recognizing her ability to help shoulder the Shepherd's burden. He also shares a significant emotional tie with his mother Muse, though he chooses not to reveal his identity to her before her sacrifice.

Over the course of the story, Mikleo grows from a cautious friend who initially hesitates to leave the safety of Elysia into a determined partner who actively chooses to share the dangers and hardships of the Shepherd's journey. He learns to assert his own worth and to accept that he can stand alongside Sorey as an equal. His development includes accepting the role of Sub Lord and using the Armatus to fuse with Sorey, allowing them to fight as one entity.

As a water seraph, Mikleo wields water-elemental abilities. He is a versatile combatant who uses a long staff as his primary weapon, fighting at mid-range and employing both offensive artes and supportive healing techniques. He has a natural proficiency for water manipulation, which he uses to unleash attacks and to assist his allies. Notable among his techniques are his water-based artes such as Aqua, and he can also use the Armatus to merge with Sorey for greater power.
