Yakushiji is a seemingly carefree, hopeless romantic who has terrible luck in love. He lives in Asakusa. Highly superstitious, throughout the manga he can often be seen reading his horoscope and visiting shrines for luck. However, his laid-back demeanor hides his fighting strength and his martial prowess. He often lapses into melancholy and seems the smartest and wisest of The 4 Heavenly Kings. When he was younger, he and Chiaki used to be best friends, and he often thinks about her. Maeda has an intense dislike towards Yakushiji due to his relationship with Chiaki.
