Keijo (manga)
Japanese manga series
Keijo (競女), also known as Hip Whip Girl, is a Japanese manga series written and illustrated by Daichi Sorayomi. It was serialized in Shogakukan's shōnen manga magazine Weekly Shōnen Sunday from July 2013 to April 2017, with its chapters collected in 18 tankōbon volumes. It follows a gymnast participating in a fictional women-only contact sport, where players use only their breasts and buttocks to tackle opponents. An anime television series adaptation produced by Xebec aired from October to December 2016.
Plot
In an alternate reality, the women-only competitive sport keijo becomes a fad in Japan. The rules for the game are simple: the match is held in a swimming pool stadium. Participants must stand atop circular platforms floating in a pool, referred to as "lands". They can defeat their opponents by knocking them off their respective platforms and into the water, using only their breasts or buttocks. The sport attracts millions of viewers across the country and boasts a lavish prize pool. This prompts many aspiring athletes from different sports to try to succeed in keijo.

Why this record matters
The phrase “japanese manga series” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q17228387. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2013, 2017 and 2016.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
