Tsubomi has light-colored short hair that stops at her upper neck with light-colored eyes. She is tall and usually wears a t-shirt with jeans.
Tsubomi first appears outside of Suzume's school. She greets Shishio with his first name, "Satsuki," making Suzume instantly know that Tsubomi is Shishio's ex-girlfriend, since Shishio had just told her that the one who used to call him "Satsuki" was his ex-girlfriend.
Being Shishio's ex-girlfriend, Tsubomi could easily see underneath Shishio as a person. Because of that, she would speak what was on her mind to him.
She appears once again in Chapter 66. When she gets back, she meets Shishio and gives some important advice to Shishio in regards to his strained relationship with Suzume. Tsubomi advises Shishio to try letting go of his pride.
