Yayoi Shimotsuki (霜月 弥生 Shimotsuki Yayoi) is a character in the series Keroro Gunso. She is one of Natsumi Hinata's friends.


Yayoi acts like a typical high-school girl. Natsumi and Satsuki are her childhood friends, and out of the two Yayoi seems the most graceful.

She's also the president of the drama club, which seems to have a few other members as shown in the rehearsals of episode 29-A, although the other members have never been plot relevant, with the few times the club comes up being when Yayoi wants Natsumi's help for one reason or another.


  • Satsuki Shiwasu-Childhood Best Friend. The two are always shown together, proving how deep their bond is.
