the hantengu clones.

An Upper Moon is one of the strongest demons under Muzan, ranked at the very top of the Twelve Kizuki and far more powerful than normal demons, while a Hashira is an elite Demon Slayer—one of the strongest swordsmen in the Corps, each mastering a unique breathing style to fight demons.

In Demon Slayer: Kimetsu no Yaiba, Hantengu’s clones have distinct appearances that match their emotions: Sekido has a stern face with sharp features and carries a staff, giving off an intimidating, authoritative presence; Karaku looks relaxed with softer expressions and wields a fan, appearing calm but cruel; Aizetsu has drooping eyes, a gloomy expression, and carries a spear, constantly looking distressed; and Urogi appears wild and energetic with wings, sharp teeth, and an excited grin

they are obviously sadistic and harsh with the intention of hurting you but they also see you as a little toy to play with as they will take you back to use and torment

Sekido embodies anger and is harsh, loud, and commanding, often taking control of the others. Karaku represents pleasure and is calmer and mocking, fighting with a laid-back but cruel attitude. Aizetsu shows sorrow and is more quiet and emotional, constantly expressing despair while still being dangerous. Urogi reflects joy and excitement, acting energetic and almost playful as he enjoys battle. Together, these clones show how Hantengu’s overwhelming emotions split into separate beings, making him unpredictable and especially difficult to defeat.
