「THE OTHERS: #12 RUBY」
(Status: alive, sane - Species: human - Linked to... Hachi Makune)

The "infamous" singer being "responsible" for Hachi's death in some way. The core data file maintainers of RUBY forced the ones of Hachi to take down the files. This didn't happen in a single row. This happened progressively. When Hachi arrived, RUBY's file was already in construction and Hachi's was partially depleted, before finally collapsing few months later. Should RUBY have never existed and there would have been no death like this. However, does RUBY really know about Hachi? The answer is no. Maybe to avoid her a shocking truth. What would RUBY think if she believed to have indirectly murdered another girl? And also, would Stella appreciate RUBY for "finishing the work she intended to do back in May 2015"? No idea.
