Page 10...Byakuran is basically the pot calling the kettle black there...
For those who do not know, Byakuran made herself youthful to live forever so she doesn't die. And in Zounose's works, she consumes peaches (Buddhist symbol of immortality) that were grown from soil made from human fertilizer to retain her youth.
So her calling out on toyosatomimi's immortality is complete irony.
