XENIX-tan witnessed the very beginning of MS-DOS-kun's existence, and from that moment on, she has always been incredibly caring and supportive towards him. In fact, their relationship is much like that of a mother and her child. MS-DOS-kun greatly admires and respects XENIX-tan for her guidance and wisdom.
