Inosuke Hashibira is implied to have married Aoi Kanzaki in the Demon Slayer series.
While the series doesn't explicitly show their wedding or confirm their marriage, strong hints suggest they ended up together. The most compelling evidence comes from the epilogue, where we see that Aoba Hashibira, one of the descendants, strongly resembles both Inosuke and Aoi. This heavily implies that Aoi and Inosuke had a child together, indicating a marital relationship.
Furthermore, throughout the series, there are subtle hints and interactions that suggest a growing affection between Inosuke and Aoi, especially Aoi's caring nature towards him as he recovers from injuries. While their relationship isn't overtly romantic, it's clear that they share a bond. The fan base commonly accepts their implied marriage.
