Valona

Valona is a succubus-class MMS unit who was given the name 'Iris' by her master Shindo in the anime series. Recognizable by her twin tails and demonic wings, she presents herself as a sleepy, whimsical figure—yet beneath that innocent façade lies a calculating operative capable of deception and manipulation. She was dispatched on a covert mission to mislead the protagonists under a false identity, revealing a sharp contrast between her playful demeanor and her tactical cunning. Despite this duality, her loyalty and emotional attachment to Shindo remain absolute. She is also the sister unit of Straf.
