Yoshioka

Yoshioka is a businessman who is seen talking to his boss on his cellphone. He is instructed to "do as planned" when receiving an important call one minute later. The call would grant a business opportunity worth one billion yen. If he missed the call, Yoshioka would be fired by his boss.
Seemingly nervous, Yoshioka agrees but his phone is stolen by Josuke immediately. Unaware of what just happened, he continues talking to his hand before he notices his phone is gone, and is then anguished over the loss of one billion yen and his job. As Josuke grabbed the phone too hard, it ended up breaking.
