Here's the sixteenth. Rukia actually has two chibis in this set I found. The first is her in Soul Reaper or Death God form with her zanpakutō.

[I do not take credit for making the chibis of the characters themselves. I have no idea who did make them. If someone knows, let me know and I'll credit them properly. But don't lie and say you made them. Let's have some maturity and not take credit for other peoples' hard work.]
