The Power of Emotion: Hantengu's character design is unique because he splits into different clones, each representing one of his strong emotions. The main image on the shirt appears to be a fusion or one of his more powerful forms.

Symbolic Headwear: The small horns on his head are a subtle but powerful visual cue, distinguishing his forms and showing his demonic nature.

The Emotional Clones: Each of Hantengu's clones, like Sekido (Anger), Karaku (Pleasure), Aizetsu (Sorrow), and Urogi (Joy), has a distinct design and personality, reflecting the emotion they embody. This makes his character one of the most creatively designed in the series.

Detailed Kimono: The design features intricate patterns on his kimono and clothing, adding depth and visual interest that makes the character stand out. These details are often linked to his abilities and the specific emotion he represents at the moment.

A Fusion of Fear and Art: The design masterfully combines a sinister, demonic appearance with a striking, almost artistic aesthetic. The dark color palette and dynamic pose on the shirt create a strong visual statement that resonates with fans of the anime.
