With you enabling her lewdness, Lilie overcame her shiness and became a strong trainer, yet, slightly on the R rated side. With you defending her, she managed to escape with cosmog and became a successful trainer, helping actively in the defeat of the Aether foundation. She may have captured lunala, but sinc eyou can turn into most legendaries, she barely uses it.
Since she became an adult, she wears you as a tight latex suit and doesn't mind fighting in underwears if she needs your powers in a fight. You love this life, especially when she plays the dominatrix with her friends.
