Farewell lasts forever.





The "Will" of this Academy City. Her body has already reached its limit after being stripped of all value by Lewis.
A faceless phantom from the outer world. Alice... Delos... and Guest. Just as he thought he had seized the world, a massive interference was thrown his way, finally revealing his true nature as "The Man Who Sold the World."
Rank: None Guest's best friend. Or perhaps, something more. Her life was ended by Lewis's gravity waves, but if you wish strongly enough, she will surely respond.
Also known as the "Sword of Delos."

Everything is infinitely blue.
The sky, the earth. A pure blue that continues forever.
Standing in that infinite "Azure" like a single bleached point, a girl remains.
—Delos.
The girl who shares the same name as this Academy City. Her true identity. Now, Guest can somehow understand it.
She was in tatters.
Or rather, both of them were.
Guest's memory cut off at the moment they were crushed by the attack of Lewis, who had seized the world.
