High School DxD (2012) Parents Guide: Is the series OK for kids?

This season features severe and pervasive sexual content, including full frontal and partial nudity (breasts, buttocks), often in a non-consensual context or through accidental exposure. Characters are frequently seen in revealing outfits, lingerie, or swimwear. Issei's 'Dress Break' ability explicitly involves tearing off women's clothes, leaving them nude. There are scenes of breast grabbing, suggestive moaning, and frequent sexual innuendo and suggestive poses. A character is imprisoned with suggestive chains…

The violence is strong, featuring frequent magical and physical combat between supernatural beings. Characters are impaled, blasted with energy, and suffer significant injuries, sometimes with blood shown. Environmental destruction is common during battles. While graphic gore is not pervasive, some characters are shown incapacitated or defeated in bloody states. A young boy is briefly depicted stabbed with a glowing spear.

Frequent use of moderate profanity such as "damn," "hell," and "bitch" occurs throughout the season, particularly during intense battles or moments of frustration. Stronger language like "bastard" is also present, though less common. Issei often uses crude, sexually charged remarks.

Major themes include conflicts between different mythological factions (angels, fallen angels, devils), the nature of good and evil, and the acceptance of one's own power and identity. There are discussions of past wars and ongoing power struggles. The theme of loyalty within the devil peerage and to one's friends is central. One character struggles with their identity as a male with female features. The threat of war between factions is a recurring theme.
