Kero Midorikawa  

, 緑川ケロ

Kero is one of the announcers for the N1 Grand Prix Net Battle Tournament. She serves as a commentator alongside Higure! After the tournament concludes, she can be seen broadcasting normally. Additionally, we observe her operating her own net navi, Toadman. For those who are unfamiliar with Japanese terminology, "kero" translates to frog.
