Demon Slayer Family

**Demon Slayer Families** (鬼狩り家, *Oni kari-ke*?) are families of Demon Slayers that affiliated themselves with the Ubuyashiki Family and joined the Demon Slayer Corps to fight against Muzan Kibutsuji and his demonic creations in the Human-Demon War in Japan plus have passed on Breathing Styles down their lineage.

## Overview

There are various Demon Slayer families over the centuries that have fought alongside other Demon Slayers throughout history. The most commonly known family is the Rengoku Family, who are practitioners and users of the Flame Breathing Breathing Style. Having produced many Flame Hashira throughout the century (until Kyojuro Rengoku's demise in 1917), the Rengoku Family has been respected and their signature technique has existed for generations. A prominent Demon Slayer family of the past was the Hoshimiya Family, whose members were practitioners of Star Breathing since the Sengoku Era.

## History

After the foundation of the Demon Slayer Corps during the year 1183 AD, the samurai under the Ubuyashiki Family's command would fight against Muzan's demon horde. Over the years, smaller families, wanting to fight for the future of Japan against demons, would join the Ubuyashikis cause against the demons that plaqued Japan.

During the Sengoku period, a family known as the Rengoku Family would join the Demon Slayer Corps, with one of its members, Enjuro Rengoku, becoming the first Flame Breathing user and first Flame Hashira. After the death of Hideyoshi Ubuyashiki at the hands of a newly demonized Kokushibo plus the Sun Breather massacre years later, the main bases of the Corps had to be moved to protect the Demon Slayer families, with the demons having no whereabouts of where these families hid for centuries till the Taisho Era. Between the timeframe of the Sengoku-Taisho eras, a few of these families would pull out of the fight and live quiet lives.

After the death of Muzan Kibutsuji, these families would continue being affiliated with the Ubuyashiki Family all the way to the current Reiwa Era whilst still passing on their Breathing Styles to future generations in the form of ritual dances, with newer families joining to become affiliated of the Ubuyashiki Family.

## Known Demon Slayer Families in Japan

### Rengoku Family

The **Rengoku Family** (煉獄家, *Rengoku-ke*?) is a battle family that began in the Sengoku period that has produced a long line of Flame Hashira ever since its family head created Flame Breathing and became its first Flame Hashira. Ever since Enji Rengoku joined the corps and his son, Enjuro becoming its first Flame Hashira, the Rengoku family has continued to serve the Demon Slayer Corps and has continued to fight against Muzan's demon progeny. After the Demon Slayer Corps was disbanded after Muzan's death, the Rengoku family has continued to preserve the Flame Breathing records and practiced Flame Breathing as a ritual dance.

### Hoshimiya Family

The **Hoshimiya Family** (星宮家, *Hoshimiya-ke*?) (Meiji Era onwards), formerly known as the **Hoshimiya Clan** (星宮氏, *Hoshimiya-shi, Hoshimiya-uji*?) during the Heian-Meiji era, is a battle family that has existed since the Heian era and were closely affiliated with the Ubuyashiki Family, acting as the family's vassals and bodyguards. During the founding of the Demon Slayer Corps, the Hoshimiya family joined the fight against Muzan's demon horde.

A notable member of the family was Gensuke Hoshimiya, a Demon Slayer who later created the Breathing Style known as Star Breathing and became the family's first ever Stellar Hashira although he was able to use Sun Breathing without Yoriichi or Michikatsu Tsugikuni knowing. After Michikatsu's betrayal into becoming the demon Kokushibo, the family permanently kept their use of Sun Breathing a permanent secret and began to be operate so discreetly with their other actions that even Muzan and Kokushibo completely forgot about them.

This was the same family where Takanori Hoshimiya, the Taisho era Stellar Hashira, is from and became its leader after the family's 'kodoku ritual'.
