"I don't need your apologies! If you feel bad about it, try actually coming in to work! Doesn't matter to me, you know! You can come 'cause you're lonely... 'Cause you're having a hard time... Or even just 'cause you happened to be in the area... Ever since the day I hired you, I figure I'm basically like a big sister to you... so you can come see me whenever you like! I told you before, didn't I?! Helping out kids like you is what us grown-ups are here for!"

Ikumi Unagiya is the owner and manager of the Unagiya Shop in Karakura Town, a business which performs a variety of odd jobs for its customers. She hires Ichigo Kurosaki sometime after the loss of his Shinigami powers.

Ikumi is a tall, curvaceous, and fair-skinned woman with brown eyes. Her raven hair, which reaches to her upper back, has bangs which part to the left of her face and is styled in a ponytail with a purple scrunchy. She normally wears a white t-shirt with long purple sleeves, tight black pants with a buckle belt, and black rubber boots. As the owner of the Unagiya Shop, she has her shop's logo on her shirt with "Unagi" written on. She wears a brown cap with goggles and work gloves. When around her son, she removes her gloves, hat, and goggles, and replaces them with an apron.

Ikumi runs the Unagiya Shop, and because she is short-handed, she relies on Ichigo Kurosaki for help. Ikumi is violent and aggressive, as she is willing to use force, usually excessively, to get her way, beating up a group of thugs whom Ichigo was fighting just to bring Ichigo to work, doing so by kidnapping him shortly after. She takes pride in her shop, refusing to change its name despite Ichigo's recommendation to do so and the mistakes some customers make. Despite her aggressive personality, she is still very caring, maintaining a stereotypical sweet-mother demeanor around her son, even when he is rude to others. With Ichigo, she has occasionally shown her motherly side in giving advice to him, and offering him shelter in his emotional state, considering herself an older sister to Ichigo.

Expert Hand-to-Hand Combatant: Ikumi is a very fearsome fighter, effortlessly pummeling an entire gang on her way towards Ichigo.

Enhanced Strength: Despite her slender frame, Ikumi is surprisingly strong. She can launch several delinquents a noticeable distance, and easily subdues Ichigo by effortlessly grabbing him in a headlock and dragging him away.
