Indura

is the true nature of demons that possess seven hearts and a power level exceeding 50,000.

Appearance
Indura are varied in appearance, resembling monsters, chimeras, or mutated animals.

Personality
Despite their origin as a member of the Demon Clan, they are essentially wild creatures without the ability to reason, having exchanged that as well as their original form for power and only have a desire for destruction.

Description
In order to attain and transform into their Indura form, a demon must have a power level of at least fifty thousand; a demon with a power level lower than that will die due to not being strong enough to survive the strain of the transformation. Next in order to make a pact with the Darkness within them, the Demon would then have to sacrifice six of their seven hearts in order to initiate the transformation. If successful the resulting Indura would thus then have gained massive amounts of strength and power but at the cost of losing the ability to have rational thought and simply becoming beasts that react and follow their basic instincts to destroy everything around them.

Known as "legendary beasts", the Indura are widely feared even within the Demon Realm, and are known to come in different types. Indura bearing titles such as Ashes (灰燼, Kaijin), Time (星霜 Seisō), Resentment (怨嗟, Ensa), Thunder (遠雷, Enrai), or Retribution (業報, Gōhō) are still roaming around the Demon Realm.

The Indura resulting from the Commandments who got the decrees bestowed upon them by the Demon King are called the Induras of Favor (主恩, Shuon), who are noted to have a power level above regular Indura.

Abilities/Equipment
The Induras are noted to possess absolutely massive power; when Derieri and Monspeet transformed into their Indura Forms they both possessed enough power to overwhelm and nearly kill three of the Four Archangels of the Goddess Clan, who match the Ten Commandments in terms of raw power. Even Meliodas, the former leader of the Ten Commandments, stated that the only "real" way to defeat them was to simply allow them to rampage to their heart's content until they simply kill themselves from exhaustion, further proving the depth of their power.
