Ritsuko Iwashita (岩下 律子 Iwashita Ritsuko) is a minor, recurring character in the Baka to Test to Shoukanjuu series. She is a student in Class 2-B at Fumizuki Academy and is good friends with Mayumi Kikuiri.
In her debut appearance in Volume 1, she seems strong at Mathematics, but Mizuki Himeji defeats her through the use of a special bracelet she acquired thanks to her own high score.
In Volume 2, she and Mayumi fight Akihisa Yoshii and Yuuji Sakamoto under Mathematics in the first round of the Summoned Being Tournament, and despite having a 116-point lead on Akihisa, she loses due to his better control with his Being and his teamwork with Yuuji.
She makes a brief appearance in Episode 1 of the Matsuri OVA, helping out her classmates with preparing for the school festival.
Her Summoned Being differs the most amongst the series' media. In the manga adaptation, it wears a black ninja uniform and wields a katana. In the anime adaptation, it wears Western-style armor and wields a sword. In Episode 2 of the Matsuri OVA, it has bunny ears, wears normal girls' clothing, and wields a giant hammer.
