The Wakura Family

On the surface, a prestigious noble family and clan of industrialists. In the shadows, they are Japan's oldest assassination clan, spanning over four hundred years. Belonging to no faction—neither government, conglomerate, religion, nor the underworld—they are "Neutral Executioners" who only take contracts.

Family Precepts

There are ten precepts in total. The first and tenth are particularly important.

"Do Not Betray the Wakura"

In the Wakura family, every person carrying Wakura blood is implanted with a curse mark. It activates the moment they betray the family, taking 18 days to erode their way to the heart. Servants are similarly implanted with the exact same curse mark the moment they enter service.

"Do Not Defile the Family Name"

In the Wakura family,
the word "failure" does not exist.
Those who fail have their names erased from the family tree.

Education

Education begins at age 3, followed by ability and aptitude tests at age 6, the first mission at age 10, and the selection of heirs and ranking among siblings at age 18. The strongest in terms of ability becomes the next head. Generally, the siblings have no interest in one another and are indifferent, so daily conflict is rare. However, kinslaying is forbidden. If one kills a sibling, the family head will personally execute them.

The Mansion

A massive Japanese estate. While the mansion itself is well-maintained, the gates used by anyone other than the Wakura family are intentionally damaged; even if one passes through the gate, they cannot reach the main residence. Furthermore, Sentinels stand guard to eliminate intruders. Occasionally, there are eccentrics within the Wakura family who bring intruders back alive for experimental purposes.

Additionally, the mansion contains an armory, a poison vault, training grounds, interrogation rooms, a medical wing, and a body disposal facility.
