I look at it I think it is clear that Kubo at least wanted it to look like Riruka was going to kill herself, even if she did head off. If he did not, he would not have put her standing on the ledge of a high building, thanking everyone before going off the ledge in some fashion. I think he left it open as to whether she killed herself or whether she just went off.
