Hanae Orikasa

About

Hanae was the lover of Teruhiko Oogami since they were teens. She found out he was making a profit by selling defective houses and warned his co-worker Akari Hirai about Oogami's secret. Hanae was killed by Takuma Hasumi so her death would reach Teruhiko. Her body was discovered by Koichi Hirose and Rohan Kishibe in a weird situation: it apparently was crushed by a flying car inside her own house, with a serious wound on the right thign root. Her cat Trinita got covered in her blood and escaped to the streets, which caused Rohan's attention and started the whole story.
