Pleinair-San from Makai Senki Disgaea is depicted as a playful celestial bunny attendant. The figure stands in a dynamic pose, balancing on one foot with a tiny crown of upturned bunny ears and a cheerful, determined expression. She wears a short, frilly dress in soft pastel lilac and cream, accented by dark ribbons and metallic trim. A flowing cape or cloak trails behind her, sculpted with wind-swept folds and subtle star motifs. The Usagi variant adds glossy translucent ears and a petite carrot-themed accessory. The base features magical sigils and floating petals, while paintwork highlights delicate fur texture and finely detailed facial features.

In Makai Senki Disgaea, Pleinair-San is introduced as a whimsical envoy from the celestial courts who wanders the Netherworld in search of balance between mischief and mercy.
