Penelope Penny who is the Hermione figure she's very talented good at spells a little detective. Agatha who is Simon's girlfriend who I kind of like it's hard to describe why they're dating in the first place. The book hits you in weird ways there was a point where when you get a little bit more backstory on the character and somebody asked, "Why see like Simon Belmont yes what is it from castle from Castlevania"
