Meanwhile, section chief Nora drops by the Katsuragi residence to see Elsie.  It sounds like the Hell Bureau of Peace has issued an order to the loose soul team to search for residents of Heaven.  Kanon/Apollo is currently at the Katsuragi residence.  Is this a coincidence?
My dear sister has her wings back.

Mi hermana ha recuperado sus alas.
Minha irmã está com 
suas as asas de volta.
