She is a heavy drinker and as a result is often broke and unable to afford food. Soon after Mahoro arrives at the Misato household, Shikijo starts inviting herself for dinner on a daily basis despite Mahoro's protests.
Shikijo and Mahoro often compete with each other, usually with Mahoro emerging victorious except when it comes to insults. She has much larger breasts than Mahoro, which she flaunts when comparing herself to Mahoro or in taunting her. Her large breasts are also a focus of her many attempts to seduce Suguru.
