Hotaru Haganezuka

Hotaru Haganezuka is a swordsmith affiliated with the Demon Killing Corps.

Appearance
Hotaru first appears in the manga when he delivers Tanjiro Kamado's katana to him at Sakonji Urokodaki's home. He appears wearing a sunflower patterned robe and a large woven hat with floral wind chimes hanging from it. His head is wrapped in a spotted cloth and his face is concealed by a Hyottoko mask (wooden festival mask), similar to Sakonji.

During the Swordsmith Village Arc, he appears with the same clothing but is seen with a more muscular build compared to his initial appearance. When the village comes under attack by Gyokko, his mask was broken during a scuffle. It is shown that he has long black hair coupled with sharp eyes and distinctly-shaped eyebrows.

Personality
Hotaru is a rather hot-blooded individual. He seems to show very little care, if at all, about anything besides the swords he creates. His passion for swords is so strong that he would be able to speak about them for long periods of time. His passion is also noted to be unique even among the people from the Swordsmith Village.

The same passion that gives him the enthusiasm and extreme dedication in creating swords is also the reason why he would become enraged (usually in a comical fashion) towards swordsmen who would break his creations (Tanjiro being the most frequent one); even when their reasons are valid. When angry he would usually calm himself down by eating dango or by having others pin him down. It is later on shown that he is an objective-oriented person; never revealing his name in the swords he creates unlike other swordsmiths and persistently forges swords despite having lost clients due to his eccentric behavior.
