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?
More people means we finish faster, 
and we don't mind if you join.
.كلما زاد العدد كلما تمكنّا من التنظيف أسرع ولن نمانع إن انضممتم لنا
Dann geht es umso schneller.
Und Hilfe schlagen wir nicht ab.
Cuantas más seamos, antes acabaremos.
Cuantas más seamos, antes acabaremos.
Ça ne nous gêne pas,
et on finira plus vite.
Più siamo, prima finiremo,
e non ci dispiacerebbe se ti unissi a noi.
Quanto mais gente, mais rápido.
Eu não me importo.
Вместе быстрее справимся,
да и с тобой веселее.
