Please Twins! (おねがい☆ツインズ, Onegai Tsuinzu, Onegai ☆ Twins), is an anime television series, scripted by Yousuke Kuroda and produced by Bandai Visual, which was later adapted into a light novel and one-volume manga series. It centers on a family of three teenagers in high school all living together who are unsure which two of them are related to each other due to a reference from an old photograph.

It first aired in Japan on the WOWOW satellite television network on July 15, 2003 and finished with a total of 12 episodes plus a later OVA episode released on DVD. The series was later adapted into a light novel in 2004, which spanned a total of two volumes and, soon after, into a short one-tankōbon manga version (authored by Akikan), which was serialized in MediaWorks's Dengeki Daioh magazine in September 2005.
Plot
Please Twins! is a story about three high-school students: Maiku Kamishiro, Karen Onodera, and Miina Miyafuji. The three were drawn together by a photograph of their childhood home which later makes all of them seek out the house in the picture. However, the picture shows only two children, a boy and a girl. The three conclude from this that only one of the girls, either Karen or Miina, can be related to Maiku. The other must be a nonrelative. The only other identifying feature of the pair in the picture is that the boy and the girl have eyes of the same unusual color, a feature that furthers the ambiguity as all three of them share the same eye color.
