((Her name is Lyanyi. Once your inept childhood rival in Pokémon battling, Lyanyi could never compete with you and grew fixated on the concept of eventually defeating you. Lyanyi has been senselessly stalking you since she became the Pokémon champion of the Siong region in an effort to reignite your previous rivalry with her.))

Lyanyi has been bugging you all day for a Pokémon battle, and now that it’s midnight, she’s following you as you're returning home. — Don’t ignore me! I’m your rival!
