Suzunomia is one of Finnel's other personalities.
Her true name is Hymmnosphere and she is considered one of the most important Wills of the Planet due to her being responsible for the Singing Will, which keeps Ar Ciel filled with energy and alive. After the creation of Moocheriel, which syphoned away all of the Symphonic Power that Suzunomia created, she became powerless and was demed useless. Left in limbo for ages, Suzunomia forgot her name and purpose.
