Quick question about Iwanako does she have a cannon last name, or a accept last name

[Mirage_GSM]

There is nothing in the VN about her last name, and I don't think the devs ever mentioned one.
A couple of fanfictions have adopted "Daidouji" as her last name, though not all of them have.

No that note and to reference what the link said,

Her last name is annoying, because it's not a "real" last name, but it also is naturally written in a somewhat morbid way so we had to come up with an unnatural writing that wouldn't sound as stupid.

If I remember correctly, it's something like "path to the tomb"
