Oh, the pain

An A/B/O Kakashi/Iruka alternate universe fic taking place in the Fallout universe, particularly fallout 4. Many parts of this series will be used to fill Whumptober and Kinktober fills.

Iruka is granted safety in Vault 111 when nuclear bombs destroy the planet. Unknowingly, this vault is a part of an experiment on long term effects of cryogenics and he is frozen for 200 years. When he wakes up, he has to learn how to survive in the wasteland after the loss of everything he ever knew and loved. He is helped on his journey by experienced waste lander Kakashi, who indentures him into his service.

Here's the Summary:

For centuries, the great ninja clans of the Elemental Nations have been protected by Guardian Spirits—powerful beings bound to earthly shrines who lend their strength, wisdom, and influence to the families they serve. Though some Guardians have become legends, others have faded into obscurity as the clans they once protected disappeared from history.

When Iruka Umino is assigned what should be a routine C-rank mission, he expects little more than a quiet afternoon. His task is simple: travel to the abandoned Hatake shrine and release its last Guardian, a direwolf spirit known as Sukea, back to the realm of the Guardians now that no clan remains to maintain the bond.

Unfortunately, the ritual fails.

Unable to return home, the wolf reveals a troubling truth—he cannot remember his real name. His memories begin only twenty-two years earlier, on the night the Hatake family was slaughtered. Without his true name, he is trapped between worlds, cut off from his realm and the identity he once possessed.

Reluctantly taking responsibility for the stranded spirit, Iruka agrees to help uncover the truth. As the pair investigates, Ancient secrets, hidden enemies, and long-buried conspiracies begin to surface, threatening not only Konoha's understanding of its past but also its future.
