Hana Kurusu has green eyes and chin-length blonde hair styled into a bob, with blunt bangs and ends that have a deep inward curl. Due to the Angel's influence, the girl herself looks angelic, possessing a pair of feathered, bluish-white wings on her upper back and a yellow halo over her head; similar to Sukuna within Yuji, the Angel can manifest a mouth on Hana (like her cheek or hand) to speak through.

Initially, during the Culling Game, Hana wore a tan, oversized sweater. It had a thick, capelet-like top portion with a high collar, which reached over her chest and was vertically striated (as were its tight sleeve cuffs and bottom hem); the sweater overall was long enough to go just above Hana's knees. For lower wear, the girl donned black leggings tucked into light-colored, ankle-high boots with high heels.

Hana is a calm, friendly, and well-mannered person whose actions betray a brave, outgoing nature. She wants to help people and was inspired as a young child. How Hana's relationship with the Angel started out is unknown, but she has never expressed an issue with the ancient sorcerer's possession of her, hence the Angel's decision to live in symbiosis with Hana and leave the girl in control of her body.
