Enoki Sachi

A student who died in an accident before the war. A sort of upper... upper... upperclassman to Yuna and everyone else. Mature, composed, and gentle, though somewhat mischievous and full of curiosity.

After her death, she returned as a ghost and now watches over the students from the roof. Seeing girls pursue the feelings hidden in their hearts is her joy.

When she meets Yuna, she decides that helping is even better than watching.
