Rushai was born in Furore Household whose bloodline focuses on anger! The loud and harsh roars were common in their house and its surroundings! Whole families subservient to this household also were affected by this as their bloodlines were under strict control of Furore Household.
The percentage of their purification was decided upon their achievements and family's status! As for Furore Household, they had yet to have descendant born with pure bloodline!
Pure bloodlines are ranked as Overlord! And Rushai himself has been born with Monarch rank, which was very good as he was the oldest son of current leader of household. Such bloodline already settled him as next head of household.
"Rushai! I fucking challenge you!"
Young brother suddenly popped out from nowhere! For Furore demons, the easiest way to raise their bloodline rank was through the anger of course! Even more, for young kids like Rushai and his brother!
