Bakkun is a small magical creature from the fairy world. Its body transitions from baby blue to pastel pink at the midsection. Large, multi-colored eyes display pastel purple, pink, teal, and yellow hues with star-shaped shine effects. A prominent pink star adorns its forehead, encircled by three teal circles. Around its neck sits a white collar resembling lace or flower petals.

Two puffy pastel pink wings float detached from its body like fairy wings. A short golden tail culminates in a large star-shaped structure featuring a moon carving that encases a central blue gem.

The creature possesses a rarely seen secondary combat form, large and monstrous in appearance. The Fairy Queen can activate this form when necessary. Specific details about its full appearance or combat abilities remain undocumented.

Bakkun’s name derives from "baku," referencing both the tapir and a mythological Japanese spirit. According to legend, baku spirits consume nightmares, allowing distressed individuals peaceful sleep. Excessive summoning risks the baku devouring a person’s hopes and desires if nightmares prove insufficient. This myth establishes Bakkun’s foundation as a nightmare-devouring entity.
