"Toguro Brothers are a pair of siblings who are known for their exceptional skills in combat and their ruthless demeanors. The brothers are the main antagonists in the anime and manga series ""Heroes, Demons & Villains"", and their appearances in the series often bring danger and chaos.

The older brother, Toguro Ani, is known for his immense strength and resilience. He has the ability to increase his muscle mass, making him nearly invincible. His younger brother, Toguro Ototo, on the other hand, is the more cunning of the two. He is a skilled strategist and manipulator who often uses his intelligence to get the upper hand.

The Toguro brothers are both former demons who were once members of the demon world's elite team, The Four Beasts. However, they chose to join the human world and become mercenaries, using their abilities to carry out dangerous missions for those who could afford their services.

Despite their fearsome reputations, the Toguro brothers are not without their weaknesses. Both brothers are haunted by their past and have a deep sense of regret for the actions they have taken. Additionally, their reliance on their skills in combat means that they are often caught off guard by opponents who use other methods to gain the upper hand.

In spite of these vulnerabilities, the Toguro brothers remain a formidable duo whose actions have a significant impact on the plot of ""Heroes, Demons & Villains"". Their presence in the series serves as a reminder that not all heroes are good, and not all villains are evil."
