sekido

As a holder of the fourth highest title in the Twelve Kizuki, Sekido was an extremely powerful demon. His Blood Demon Art enables him to create bolts of lightning to incapacitate his opponents, making close combat against him extremely dangerous. In addition, as one of Hantengu's emotional manifestations, Sekido was effectively immune to decapitation from a Nichirin Sword, meaning his only weaknesses were sunlight and the possibility that Hantengu's main body should die, and the demon took extreme measures to make sure the latter did not happen

looks: Sekido (積せき怒ど, Sekido?) was a tall young man with a lean muscular build, dark long spiky hair that goes past his shoulders with a reddish tinge, and narrow, deep red eyes that have the kanji of Upper Rank (上じょう弦げん, Jōgen?) engraved on his right eye, and the daiji for Four (肆し, Shi?) engraved on his left. He had brown skin, two prominent curved horns on his noticeably shrivelled and discolored reddish-purple forehead and markings under his eyes that give his face a cracked appearance. He also had the kanji for "anger" (怒, Ika?) etched into his tongue. As a demon, Sekido had pointed ears and sharp nails on each finger. He was usually seen wearing an irritated or enraged expression on his face. Sekido wore the same asymmetrical kimono as Hantengu, as he was formed from Hantengu's headless body. He also wore a pair of zōri and a violet obi. and was always seen carrying around a Khakkhara (錫しゃく杖じょう, Shakujō?). When he was first formed, Sekido took the appearance of a slightly older man; he had unkempt wavy hair and a sharper nose, similar to Hantengu. It isn't until Aizetsu forms from his severed head that he is rejuvenated. personality: As the manifestation of Hantengu's anger, Sekido was in a constant state of vexation, irritation, and rage, even towards his fellow clones, which could be seen when he easily got angered when they failed to meet his expectations and were subdued by the Demon Slayers. Sekido was also seen to care very little about his brethren
