Nanahoshi is very upset.
Her summoning research has been going so well.
Phase 1 had a little hiccup, but Phase 2 and 3 both proceeded smoothly.
Phase 4, with a little help from Perugius, should have results soon.
I'm not sure with Phase 5, but it's only a matter of time.
Maybe in 1, 2 more years she can return home.
To hear that she has an incurable disease, at a moment like this, of course she's upset.
Maybe not cancer, but it's still said to be terminal.
