'Celestine' is a name of English and French origins that means 'heavenly'.
His height is similar to that of Kokuyou, his eldest son, and he has short, light-coloured hair (probably blonde like his sons').
He wears a monocle over his left eye, and as a butler, dresses in the appropriate attire.
He may be rather strict, as he called Kokuyou a fool for addressing him as 'Father' in front of guests. However, he also appears to be kind.
Little is known about Karein's early years. There is a chance that one or both of his parents also worked for the Oak family.
At some point in his life, he married an unnamed woman and had four children with her. Exactly when he became a butler is unknown, but it could have been after the Raggs War.
Karein hugs Teito and cries when he first meets him in person, thanking him for saving Mikage (in an omake in Supreme Sugar, Teito saved Mikage, and a pillar fell onto Teito. When Teito was unconscious in the hospital, Mikage made a thousand senbatsuru, folded paper cranes Japanese people give to those who are sick to wish for them to get well soon or live a long life, and prayed hard to God that Teito would be okay).
Karein said that he has always been worried about Teito, as he heard Mikage say that Teito wasn't free (Kapitel 75). After Teito was rendered unconscious and brought back to the military by Ayanami, it is likely that Karein and the rest of the Celestine family were informed of his (Teito's) condition and whereabouts.
- In the manga, he is a butler in Wakaba Oak's family. In the anime, he may have been a soldier, as Mikage remembers his father saying, 'We won' after Barsburg defeated Raggs. But in the anime Shuri also said Mikage's parent(s) work for his family. It is possible that Karein retired from military service after the Raggs War and became a butler.
