A Killion

This morning Akemi was counting numbers when she woke up. She went all the way up to 198, 199, then one million. I walked into her room told her that after 199 is 200. She said that she wanted to take a short cut to count to a million and then a killion. I asked her what a killion was and she responded that it was a number near to where the numbers end. I don't know where she got that from.
