"Secretary Ms. Fox" is suffering from cough and fever, common symptoms of cold. In Japan the onomatopoetic word of "fox" is "KON-KON", as is "cough". The mask turns into a fox, meaning she has caught a cold.The "Secretary Ms. Fox" cannot perform well as usual. Someone shows up in front of her dashingly. It’s Mr. Contac! Mr. Contac jumps on her boss’s forehead, and launches a beam, full of grains, towards her. She removes her mask and recovers from fever and cough. The “Secretary Ms. Fox” is now working energetically, as she always does.
