Perhaps it would help if you had an image or a spreadsheet-style description of each character handy. Then you could dribble out bits of description as things are unfolding. For example, when introduced, perhaps all we know is that M is the protagonist's sister. But as things develop, maybe we'll find out she has bangs that need trimming, and she often blows at them; she's tall and awkward; when she's thinking hard about something, she (fill in the blank). And so on. Also, you can have the protagonist notice something about a character. For example: J noticed, for the umpteenth time, how his sister's ears seemed to become even more pointy and quirky when she was in an uncomfortable social situation.
