Anri is a Sexaroid who fled with Sylvie from the space station Genaros to Earth. During their escape, Anri was badly wounded, which forced Sylvie to kill people around Megatokyo for their blood to keep Anri alive.
In Red Eyes, she is hired by Largo as his assistant. During a confrontation between Largo and Priss, Anri stabs Priss when Largo tells her the truth about Sylvie's death; to which Priss explains her reason and asks Anri for forgiveness. Anri is then killed when she blocks an energy blast fired by Largo toward Priss, but Anri forgives her before she dies, while Largo mocks her sacrifice.
Anri is voiced by Yuko Mizutani in Japanese and by Katherine Burton in English.
