With angel in this world being control by whatever that "malice" thing is, Irys is literally a symbol of Hope for them seeing as how she is a Nephilim.
Meanning that Irys's demon parent somehow manage to get her angel parent's freedom for at least a while to conceive her before this happen.
Those golden weapon has been a recurring thing in this series in both Choco and Aloe, but Choco can wake up from them so maybe there is Hope for her petrified parent here. Also, that flower look like the same kind as the one in Aloe page.
