Shin Reglia/Relationships

Anos Voldigoad
Shin is extremely loyal and respectful to his master. He is considered as Anos' most devoted subordinate, as he requested the rewards of his bet with Anos being that he is allow the permission to reincarnate himself so he could serve Anos again in a new life. He had to choose between saving his daughter by spreading the rumors and legends of the Fictional Demon King Avos Dilhevia, lest she disappear due to the lack of belief in her lore on account of her being a spirit or preserving his loyalty to Anos in exchange for dooming his daughter to non-existence. He chose his daughter, though his seeming betrayal of Anos continued to haunt him up until the present. Yet, after finally reuniting with his family, Anos assured Shin that he would have ordered him to make the exact same decisions he made in the past, in order to protect his child.

Reno
He loves and cherishes his wife as she taught him how to love and to truly change for himself and not just for Anos or for her.

Misa Iliorogue
Likewise, Shin also cherishes his daughter and does absolutely everything to protect her. This led him to waver between being loyal to Anos or saving Misa's life by spreading the rumors of the fake Demon King.

Kanon
Shin considers Kanon to be the only true threat to both him and his master Anos, he has high respects for the human Hero as he was the only swordsman to ever best him in pure combat (at least once), and it was from this defeat that inspired him to become stronger than he ever was before. 2,000 years later, he has trusted the young reincarnated Hero with his daughter Misa as they became lovers.

Nosgalia
Shin considers Nosgalia to be his sworn enemy as he has tormented his family for millennia and forced him to betray his master to protect his daughter.
