Takemikazuchi (タケミカヅチ) is a god of thunder. He is also sometimes identified as a god of swords. A significant god, he is of high standing in the heavens and is known for his skill in combat. His most well-known shinki is Kiun.
He was dispatched by the heavens to the vicinity of the entrance to Yomi in order to eliminate the previous incarnation of Ebisu, who was suspected of being "The Sorcerer".
Appearance
Takemikazuchi in chapter 35
Takemikazuchi's appearance is that of a relatively young man, somewhere near Daikoku and Yato's ages appearance-wise. He has long, straight dark hair that is swept back, with two long fringes hanging from above his forehead over his ears. His long curved eyebrows are his most distinctive facial feature.
In his first appearance in Chapter 35, when confronting Ebisu near the entrance to Yomi, Takemikazuchi is seen wearing combat gear consisting of black pants, boots, gauntlets and a Haori with a sash made of what seems to be leopard fur with a sheathed sword attached to it. In this appearance, Takemikazuchi's face (as well as his shinki's) is completely obscured by a large piece of white cloth, showing only some of his hair.
His is seen wearing a set of clothes similar to the garbs worn by Shinto priests.
Personality
Loud and carefree, Takemikazuchi has a very dominant personality. His behavior stands in stark contrast to Kiun's stern and reserved disposition. He can also be quite lazy, expressing reluctance to fulfill the mission he was entrusted with by the heavens at one point. Fitting his reputation as a god versed in combat, he seems to be bored with how peaceful Takamagahara is at present, claiming that he would've liked it if it was under some kind of threat for a change.
Takemikazuchi has a strong desire to obtain a blessed regalia, especially after seeing how powerful Kazuma's attack on Kiun was despite him being just an earring. In one conversation with Kiun, he even commands him in a somewhat comic fashion to become his blessed regalia (albeit Kiun's opinion on the nature of blessed regalia is very different from his master's).
