Sumire Kousaka

Sumire Kousaka (高坂 すみれ) is a character in Zombie 100. She is a former violin instructor that lives neighboring Akira Tendou, along with her husband Mikio Kousaka.

Story
Sumire first appeared hiding in her apartment with her husband Mikio Kousaka. She told Mikio that it is hopeless, and that they were going to die, but just then Mikio noticed Akira sliding down a plumbing pole outside their window. When she heard her husband gasp, she ran to his aid thinking that a zombie had climbed up, but was surprised to see that it was Akira.

She asked him to come into their home to help them, but Akira told her that he needed beer so he was going to go shopping. The Kousakas asked him to get them some food, and toilet paper, and Akira gladly agreed.

When Akira got back, he found their apartment destroyed and covered in blood, presumably meant that both Sumire and Mikio is dead.

However it is later revealed that during Akira's excursion, the Kousakas had managed to escape their apartment in time. Seeing Akira's determination to live his life to the fullest despite the odds, the pair decide to make it their dream to travel the world before they die. They resolve to try and fight their way to an airport in hopes of commandeering an airplane, and hope to find Akira along the way.
