1 2 3 4 We Are Cells at Work 1 2 3 4 We Are working! Hoo!

Today I'll transport the oxygen, oxygen again Through corner to corner throughout the body However, in this vastity, I always get lost and lost I'm always helped by these cells at work Alright, let's go! I'll get to work! We will get to work! Training a lot every day, every day Ooh! Today I'll eliminate and remove the germs again Bacteria and virus, come out! I absolutely won't let them run around and around We are professional cells at work! Alright, let's go! I'll get to work! We will get to work! To the battlefield every day, every day! I'm a unique cell in midst of 37 trillion cells When are we be able to see each other again? For somebody's sake (For somebody) We work hard (Work hard) You and I are working frantically For everyone's sake (For everyone) We are risking our lives (Matter of life and death) Keep the pride - Health・Comes・First! Watching and monitoring our world's peace Our jobs cover all the place Tension up when we receive an order Going all out, we are working cells Alright, let's go! I'll get to work! We will get to work! Dramatic every day! Is there any abnormal condition? Check it check it Oh boy, can you breathe? (Good job! Here, a cup of tea - Oh, thanks) Let's go! Let's go! Work? Work! Somehow I love this job so much! To accomplish the work that we must do We won't cry, lose, die or give up! For somebody's sake (For somebody) We work hard (Work hard) You and I are working frantically In order to live (To survive) We will go all out (With full energy) Just one mission - Health・Comes・First! For somebody's sake (For somebody) We work hard (Work hard) You and I are working frantically For everyone's sake (For everyone) We are risking our lives (Matter of life and death) Keep the pride - Health・Comes・First! Work? Work. Work? Work! Work!!!
