did kuina kill herself

Kuina from One Piece did not explicitly kill herself in the official story. According to the canon account by her father Koushirou, Kuina died after falling down the stairs in what was described as an accident. However, this cause of death has raised questions and theories among fans. Some speculate that Kuina's death might have been suicide or covered up as an accident, given the unusual circumstances of someone as strong as her dying so suddenly and "trivially." Despite these theories, the official storyline treats it as a tragic accident that motivates Zoro to become the greatest swordsman in her honor.
