No obviously Genji Shannon and Kanon are "human" or at the very least they are "people" since that is implicit in the red truth.

However since they are included in the 18, then what about the other furnitures?

If furnitures qualify as "people" then the stakes and the siestas can't possibly exist on rokkenjima.

If they do not qualify as people then Beatrice has practically indirectly admitted that Shannon Genji and Kanon are not furnitures. that happened when she said:

Spoiler for reply for crazysjd89:

Uhm at a certain point Eva says: The one who killed Nanjo was definitely a human! and then i think she added something like: "of course it was human with magical powers".
Anyway when i talk about "reconstruction of facts" i mean what is been shown in the game and to battler in the meta world. For example: according to Eva Beatrice's reconstruction of facts Natsuhi and Krauss were killed by siestas. In the case of Nanjo she was the one in front of him. This of course doesn't mean she couldn't say that she animated a body to perform this duty, however that still be a change of her reconstruction, or if you prefer an additional information.
