Adasenshi are bipeds averaging 1.8 meters in height. They have two arms with hands for fine motor manipulation. The species is universally pale white in skin tone due to their nocturnal habits. Adasenshi have overly large eyes for seeing by moonlight.
Due to their sensitive eyes, adasenshi have to wear protective vision devices when going out in daylight. Their skin is also vulnerable to solar rays mostly harmless to other species, requiring full body clothing or, more commonly, screening cream applied to the exposed skin.
