With her onii-chan prior to getting his afro, 8 years ago

Kaede Matsushiro is the little sister of Ken Matsushiro. She has an allergy to cow dairy, and is the reason why Ken is passionate about minimizing the use of milk and cream and his baking.

She had a very serious allergic reaction once eight years ago, and nearly died. This was when Ken was still working at the main branch and his hair was in a ponytail and he had not gotten the afro yet.
