Orie Lewak

Kaguya's caretaker and constant companion, who accompanied her in her search for Riku.
She is troubled by the fact that Kaguya, her master, does everything by herself, so she fears that she's not properly fulfilling her responsibilities as her caretaker.

She takes her job very seriously, but her stubborn, no-nonsense approach, and her clumsiness can make her come across as awkward at times.

Electronics are quite literally a foreign concept to her, much to her chagrin.
