The physical ranged DPS role quest line for Endwalker introduces two characters, Kisei and Minato. The story indicates that the hyur girl, Minato, was married to Kisei's son. However, the story inaccurately describes Minato as being Kisei's stepdaughter. She should more appropriately be called her daughter-in-law. A stepdaughter is a child of one's spouse by a previous marriage, which I don't believe to be the case here, as Minato is an orphan.
