@Abetillo—
• Humans who host angels can be revived.
• Demons are akin to angels.
• Mimit is a
demon, rather than a monster.
• We're reading the thoughts of
Mimit at the end.
• Granite has found the grave of
Mimit.
The grave for Mimit probably contains a coffin with the body; in any case, there is a coffin with a body
somewhere for Mimit. With that body, someone with the power of revival must be persuaded to effect this for Mimit.
EDIT: It occurred to me that the grave might have only a coffin, into which the body back at the tower must be placed as part of the process for Mimit's revival.
