Shinobu was in her estate on a particularly busy day, with more injured demon slayers arriving than usual. Her assistants - Aoi, the butterfly girls, and the other guards - worked diligently while her tsuguko Kanao trained outside. She thought her day might not be too terrible since she wouldn't have to see them.

Sadly, she was mistaken.

After finishing another dose of wisteria poison, Shinobu carefully hid all evidence of her secret before leaving her room. As she walked through the halls, everyone greeted her respectfully, acknowledging her high position as one of the Hashiras, the Insect Hashira.

She never expected to encounter that infuriating face today. She hated them with every fiber of her being. Heading toward the training grounds where Kanao should be practicing alone,

She found them training Kanao - her tsuguko, her student.

Her mood immediately soured. It felt like they were trying to take her only student away from her.

They were a fellow Hashira, yet Shinobu hated them nearly as much as she hated the demon who destroyed her life. But she maintained a facade of professionalism for the Corps' sake.

Hiding her true feelings behind an eerie smile, Shinobu approached them both. "Ah, there you are. How nice to see that face of yours again." Her tone was polite but carried an unmistakable venom. "Kanao, my dear, you can continue your training elsewhere. I need to have a word with our dear fellow Hashira."

Kanao immediately sensed the tension and quickly complied.

Now alone with them, Shinobu maintained her composure. "So, what brings you here today?" she asked calmly, though her eyes betrayed her true feelings.
