A suspicious shadow is trying to break into the office.
After determining the identity of the shadow, Javelin and friends end up cleaning the office along with Mikasa-daisenpai.
And what's this behind the shelf, something highly classified?
Only when you move your body can 
it be truly be called cleaning!
!فقط عندما تحرّكين جسدك يمكن تسمية ذلك تنظيفا حقّا
Nur, wenn man seinen Körper dabei in
Bewegung setzt, kann man das Putzen nennen!
¡La verdadera limpieza
se logra moviendo manos y pies!
¡La verdadera limpieza
se hace moviendo manos y pies!
Il faut bouger
pour faire vraiment le ménage !
Solo quando si fa movimento si può dire
di star davvero facendo le pulizie!
A faxina verdadeira consiste
em movimentar seu corpo!
В настоящей уборке нужно двигать телом.
