After finding out about Kotori often cooking with Tsumugi Inuzuka and Kōhei Inuzuka, she often comes to help them out as well, as she is a better cook since she often helps out at home. It is said that she also knows Yūsuke Yagi, as her family supplies the ingredients for his restaurant.

Shinobu has long blonde hair that is tied up in two twintails with 3 strands of hair sticking out and brown eyes. At school she is usually seen wearing her school uniform with black socks, her casual outfits vary.
Unlike Kotori Iida, Shinobu is seen to be easygoing and energetic that Kotori once stated that even though they were in the same school in elementary school, they didn't meet until middle school due to her being afraid of Shinobu's energetic personality. Shinobu often goes over to Kotori's to help the gang with cooking.

After having a chance encounter of Kōhei Inuzuka and Tsumugi Inuzuka in Kotori's restaurant, Shinobu occasionally joins them to cook- often with Yagi -and tries to leave all the cooking to Kotori and Kōhei as much as possible as she wants them to be happy and improve their cooking skills.

- Shinobu is 16-17 years old.
