|Ren's Theme ~ Break Through|
Sasaki Ren is a Half-Blood who is the master of Servant Defender. Ren doesn't affiliate with any organizations, nor does he care about them. The only person he can trust is Derwin, making Ren indirectly associated with the Chivalric Orders.
Ren has shown to have a very peculiar thought process. The best way to characterize him would be the fact that he is rather apathetic. Since Ren is an rather apathetic person, he has no regard for person's faction. He tends to overlook a person's background, even if that person is from the Demon Hunter Organization. Ren sees himself as just an ordinary human who uses demonic power. It has also been revealed that Ren has no intention of revealing his demonic powers during unneccessary times.
Although he preforms a ton of physical training, Ren has no intention to fight others. Since Ren is an experienced fighter, he knows the result of a fight does not feel good whether he wins or loses. Ren prefers to stay in shape as preparation for any future conflict. Ren has no intention to arouse conflict with others mainly because of his paranoia of unleashing his demonic power and scaring the other students.
This will be revealed later on, however rumors say that he excells in hand-to-hand combat. Ren has a rather peculiar fighting style that relies heavily on spontaneity and agility.
Ren was born in Japan and brought up in a Japanese Half-Blood Family. Ren was widely known as the "Heaven's Sword" in Japan. At one point, Ren's father noted that Ren "never cuts twice" with a sharp object. It has been revealed that Ren has been targetted by many assassins. Ren never seems to talk about his past simply because he strongly dislikes it.
