You're asking for V4?
If yes, you want to get a Violetchi, but why would you ask about getting easier to get into the Mame family? For what i know, Violetchi is in the Meme family. Anyway, Harutchi will mostly get into the Mame family unless you neglected it, then it will be in the universal family. Well, i don't think you can get a Violetchi by the Harutchi toddler.
