Yoshizumi Yukie

The managing director of Yoshizumi Transportation Company (though it is a small company with only a few people including her husband).

She is a friendly person with a no-nonsense attitude towards anyone. She has a very open personality and does not change her attitude toward anyone. She is a big sister, and when she sees someone in trouble, she can't leave them alone.

She has a manly personality and is strong in her own right. Apparently, she was a bit of a rascal in her youth, but she is too shy to talk about it, saying it was a youthful indiscretion.

She loves her husband, but her love for him is slowly fading away because he is cheating on her behind her back and leaving her to run the company.
