Luca's family expansion continues, this time meet Lucija's sister Rena. Rena is a Shiny Female Lucario, she does not appear in the beginning of the story where Luca becomes a Pokemon Trainer. She shows up in Oasis in the post-war era. Lucija when she is angry on Rena, calls her "Shiny Bitch" which is correct, because before she came to Oasis she was... let me put it bluntly, most would call her a whore, but theoretically she was belonged to Day Care, but she got paid for every Pokemon from which she was bred with. Over time, she became VERY popular in Sinnoh.
