Shokichi and his division make it safely to Mars, however they are immediately attacked by the terraformars. The other divisions are also attacked, and since there is only one terraformar in sight for each division, they feel that the threat is minimal.
That roach wasn't alone because

‫ذلك الصرصور الذي كان يتجوّل هنا لم يكن وحيدًا
Diese Küchenschabe war nicht allein,

Esa cucaracha no estaba 
sola por mera casualidad.
Ce cafard ne nous a pas
attaqués seul
Quello scarafaggio non era solo,
 non è un caso che fosse qui.
Aquela barata estava sozinha 
não porque acabou vindo parar aqui.
