Santor Agent

Personality
Santor is introduced as a cold brother to Slash, the two do not get along well and he is seen to despise Slash in every aspect. However, it is before his death that he is seen to actually care for Slash alot, and that he only wish for the best for Slash.

Past
Since young, Santor has been cold to his brother Slash. Despite being unwiling to take care of him, Santor taught Slash how to use Endure Limit, thinking that it would at least be able to keep him alive than if he relies on him for protection. Three years prior to the series, Santor left the village on his adventure. Slash threw a destiny charm to him, and said to challenge him next time when they meet, where the charm becomes the winner's possession. Though he does not show it to Slash, he was secretly looking forward to how much Slash would improve, as he walked away.

Kaerbond Forest Arc
Santor crossed paths with Slash when they are hunting for dinner. The brothers had a quick fight, which ended almost immediately with Santor winning. Santor not only dispise Slash for his sword, but also threatened to break it if he continues to be in front of him, where Slash left in a foul mood. He later succumbed to the charm curse and took the alias 'Akuma', and attacked Slash and co. He was having an easy victory against Slash till Aegis appeared. He left the scene, knowing that his skills are no match for Aegis. He fought with Slash again the following day, and in the midst of battle, his helmet was destroyed and he was revealed as Santor. Just before dealing the finishing blow to Slash, Santor resisted the curse briefly and stabbed himself. Not wanting to put Slash into more danger, he asked Slash to kill him to dispel the curse, which he did. Moments before he died, he told Slash that he was impressed by his improvement, and as promised, gave him the Destiny Charm. Slash was reluctant to receive the charm and wanted Santor to live instead, but Santor soon passed on due to his wounds.
