Izanami's line was descended from dogs who lived with samurais and their descendants. After the humans' end, the dogs intermixed with wolves and build a clan that valued the samurais' ways. Not letting the dog blood die out, every newcomer has to mate with a dog or low content wolf dog. The highest rank was that of the Daimyo and the old Daimyo's blood relative with the least amount of wolf blood. If two or more candidates fit that description, a competition was held to determine who was more fit to rule.

Izanami was born to two clan members who have lived their whole lives as part of the pack. She spent the first 2 years learning the way of the samurai and necessary fighting and hunting techniques. After her second birthday, she began her training as an Advisor. Around the same time, she was filled in about a conspiracy in the pack by her parents. They revealed that their leaders were not the real leaders but usurpers that killed the first Heika, a black purebred wolf. Izanami was shocked; her only way of living and the pack's whole history was a lie. After the first Heika was killed, the usurpers tried to erase every hint of her existence. Luckily some texts about her survived. One of them included a prophecy in which the Heika would be reborn to, once again, rule the pack.

The following year she completed her training, in which her debating skills and ability to think logically even in the most stressful situations were tested and practiced. During her practice and the following year, her father worked on her fighting skills. Besides that, Izanami tried together with the other rebels to gather more information about the Empress` location. Shortly after her 3rd birthday, she was sent on a quest to find the Heika. Crossing the Japanese sea, she set out to find the dark wolf with the eyes of the falling sun.
