The Isshiki (一色) Family is one of the 18 Assistant Houses, bearing the number One (一) ​in their name.


They are part of 18 Assistant Houses and are from the First Institute, where the research focus was "Magic that Directly Interferes with Living Organisms". [1]

Like the Ichihana Family, the Isshiki also have magic that can directly interfere with the human body through the brain and nervous system. [2]

Nerve Disturbance When used it interferes with the enemy's nervous system to paralyze their five senses and their voluntary control. In order for "Nerve Disturbance" and the bio-electric current interference magic of the Isshiki Family to work reliably, it has to be used within the distance of several meters of the target. If the target were to act as a friend, and then betray the user along with inhibiting them from doing anything, then the need to use the bio-electric current interference magic at a close distance wouldn't be very useful. In the end, if one didn't mind killing the target, they would have to take action after disabling any surveillance.

Airi's signature magic, Lightning; in order for it to be used the user must perceive information through magic that is recognized by the spirit without the intervention of the brain and nervous system, which consists of two parts - magic that directly orders the body's movement and spirit. [3]

Nerve Disturbance it is the trump card magic of the Isshiki Family.[4]
