Kero is introduced as one of the announcers for the N1 Grand Prix Net Battle Tournament. She's a commentator along with Higure! After the tournament ends, we see her as a normal broadcaster. We also see the joy of her operating her own net navi, Toadman. For those who do not no, in Japanese "kero" means frog.
