Setsuna Shares Her Visions Of The Future

Setsuna uses her Garnet Orb to allow the girls to see the vision of the future. She is explaining: "When the enemy's Messiah of Silence fully awakens what you see will come true". I think the animators did a really good job of showing how haunted Setsuna is when she talks about her visions of the future.
