It could be possible that 《K.O.小拳王》 《K.O.小拳王》 is daughter of Rini/Chibiusa. The Sailor Moon 标题 (and all of the other Sailor Senshi/Scouts' titles) could pass to their future daughters.. A good theory could be that when Rini is declared the 下一个 queen, she has 《K.O.小拳王》 《K.O.小拳王》 as daughter and she will pass to be the 下一个 Sailor Moon and soon-to-be Sailor Cosmos. So I think she could be Rini's daughter.

Usagi(Serena) has got one daughter Chibiusa(Rini).
We do not know about Chibiusa(Rini) that her would have a daughter in the future.

ChibiChibi is the Light of Hope,neither not Usagi's and neither not Chibiusa's daughter.

i think 《K.O.小拳王》 《K.O.小拳王》 moon is reni's sister.

《K.O.小拳王》 《K.O.小拳王》 is not rini's 或者 serina's daughter only rini is serina's daughter

it is nether is is galexies

《K.O.小拳王》 《K.O.小拳王》 is Sailor Cosmos, so 你 could say that Chibiusa is her daughter.

《K.O.小拳王》 《K.O.小拳王》 is galixia's starseed
