The next day started as a bad day for the Tsukiyomi princess. Coming to work, she found out that she couldn't get access into the building with her key-card.
The key-card was their only means of access into the office everyday. Once you slid it in at the key slot by the door, the face scanner would read your details and make sure you face concurs with the data encrypted into the key-card.
She had attempted slotting in her key-card several times, but the machine kept reporting, "error reading card information."
"Could you please help me out here?" She asked one of the security guards who had quietly been observing her.
"Yes ma'am," he answered, walking over to her.
"Excuse me," he said as he took the key-card from her and attempted slotting it by himself.
The machine returned the same error to him. Startled, he looked at the key-card with curiosity and immediately realised it was a credit card, not a key-card.
"This isn't a key-card," he reported to the princess.
