Shinozaki, Toshio
Summary
Ayaka’s elder brother, Toshio Shinozaki, is someone she has not seen in a long time. Upon their reunion, he acts with intense hostility toward Ayaka, refusing to let her approach and viewing her as nothing more than a nuisance. He explicitly tells Narumi that Ayaka is annoying and habitually skips class, revealing that he is actually aware of her daily life despite her claims that he has been absent. Physically, he appears unwell and consumes medication known as Angel Fix. His behavior suggests a severe mental instability.
