Indra

Indra is the King of the Gods and Lord of Heaven in Hindu mythology. He is also the God of War, Storms, and Rainfall.

Appearance
Indra has a buzz-cut hairstyle. He wears circular sunglasses, an aloha shirt and has a jewel around his neck when in his leisure.

Personality
Indra has a sarcastic personality. He is also very arrogant, as he told Azazel that the ones who can use the name of "Heaven" is within his religion (referring to himself). According to Sun Wukong, Indra doesn't have any evil intention in him, but his action of supporting the Khaos Brigade from the backscene makes it a very doubtful statement.

History
Indra is the Lord of Heaven that defeated many opponents such as the Asuras and the Evil Dragon King, Vritra, which caused his soul to be spilt into four portion which end up as Sacred Gears. Indra has also previously made contact with Cao Cao before the latter created the Hero Faction.

The Heroic Oppai Dragon
Indra was confronted by Azazel after the Rating Game between between Issei and Sairaorg, where he revealed the fact that he had known Cao Cao and the whereabouts of the True Longinus as well as his alliance with Hades for a long time, but opted to do nothing and has kept that fact hidden from everyone. He even warned Azazel to keep Issei in line; if not, he will dispose him.

In Volume 12, Indra sends most of the Hero Faction (Cao Cao, Georg, and Leonardo) to the Realm of the Dead after taking all of their Longinus, claiming they have lost their value before retreating. It is also revealed by Hades the reason why he unsealed Samael from the Realm of the Dead is because of Indra's support from the back.
