Sumi Shinazugawa

Sumi Shinazugawa ( 不死川 寿美?) was a younger sister of Sanemi and Genya Shinazugawa.

Appearance
Sumi was a child of small frame and light skin tone. She had dark colored hair that was fastened in a low bun with her bangs clipped back on the crown of her head. She also had a very small face with large, blue round eyes. Sumi bore a great resemblance to her mother.

She wore a long light red kimono with an orange obi.

History
Sumi was born to Kyogo and Shizu Shinazugawa. She had 6 siblings, with Sanemi and Genya being her two oldest brother. Their father was extremely abusive to his family and she was often protected by her mother during his violent outbursts, until the day he was stabbed to death for being loathed so much by other people.

One night, as she and her younger siblings slept, Genya and Sanemi had realized that their mother had no returned home yet. Sanemi set out to find her and Genya stayed behind, shortly after which Sumi and their other siblings woke up to wait for their mother as well. She expressed worry as their mother had never been so late, dawn was approaching, but Genya tried to put her concern at ease and asked for them to go back to sleep.

A knock then rang from the door, leading Sumi, Hiroshi, Teiko, and Shuya to open it to greet their returning mother. Genya, seeing the figure behind the window and sensing danger, tried to warn them against opening but the door broke open. Their transformed mother rushed into the house, killing Sumi instantly. She would later be killed by Sanemi.

In disbelief, he quickly sensed that the manifestation of anger had appeared behind him and prepared to deliver a clear blow to his head to kill him. Realizing he will die, his life began to flash before his eye and he reminisced on his past, remembering the deaths of his siblings and mother.
