I want a fourth character.
No Alex! That's enough!
pls. Just tell me what I have to do.
Fine. Fine, you'll do anything? If you've been here for over two years, all of your characters are at level 6 or above, and their combined Earned OM is 80,000 ... you can make number four. This increases your switch cooldown to 24 weeks.

So, your characters need to meet the level requirements, not just the OM requirement. Little Rose is level 2.
