In Corpse Party: Tears of Blood, Ayaka has straight brown hair that reaches her upper back, and brown eyes. She also wears the standard Tsuki Academy female uniform, a camel blazer and skirt which have white stripes on the cuffs and hem, a white long collared shirt with the Tsuki Academy logo on the breast pocket. She also wears socks that reach to below the knee, and brown loafers. She is of average height and below average weight.
Ayaka is usually a bright teenage girl. She often hides behind her classmates, letting others lead the way. She is not a leader, but a loyal follower .Her other side is rather depressing. When put under pressure, she can go into a state of panic and resorts to hyperventilating and sometimes, fainting. When angered, she can be very quiet, and often resorts to staring at the floor and playing with the hem of her cardigan.
Her time at Heavenly Host takes a great toll on her personality and the way she reacts to situations. During her time, as the darkening swallows her, she begins to become much more aggressive and defensive, and can sometimes even resort to attacking the offender, like she did in Chapter 7, when she had a fight with Megumi. Much like Naomi Nakashima, she killed her friend Megumi while under the darkening, strapping Megumi to the windows, and slowly pulling her apart using the gear system.
