While it seemed a bit unfair that only the recruits that joined in their year would have to work in order to prevent future troubles, none of them complained. Zaos's squad and the others didn't grow only in strength last year. They also matured quite a bit. While they endured the hellish training, they came to understand why they lost so many friends and comrades in that fight. It was because they were weak. While that was only natural since they had no combat experience, just accepting it without doing anything wouldn't change anything. That was why they worked hard… Besides, even though they were just a single year older, they had to work harder in order to prevent others from suffering the same pain they felt a year ago.
