I really wonder what happened to this Kushinashi later on. I mean she looks quite young, or at least looks younger then the 3 greats so she should be alive in the present; or she died for some reason before. Delkira didn't seem like he had a wife. Seriously the guy seems like those lone wolf guys that thinks marriage is bullshit and would rather be having fun then getting a woman. Not surprising that Ameri is so invested in this story; not only to know about her, possibly, dead mother (currently we don't know if she's dead or just was forced to go back to the human world and have her memory wiped). Plus she also loves love stories considering what her favorite manga is. Its shocking that Amu-chan was so small before she was the true lust demon.
