Strelitzia (aka Litzy) doesn’t travel. At first she’s similar to Chloe and stays at school. Her Piers convinces her to audition for Poke Idol Stars (the idol game Penny’s obsessed with that Scout Noel and Kitty are in). She initially auditioned for the light music club group (so she could play her keytar) but ended up getting casted in the chuuni-esque unit. Also is dating Cilia and they’re very much in love (even if they aren’t allowed to be public about their relationship) 

Heru is the older twin (yes, it runs in the family). He’s a pokemon athlete. He’s the one who introduces the idea to pokemon athletes to Axel. Overall likes to try to help people out but is a bit of a jokester. He and his cousin Clover are often in some sort of prank war
