来自12个星球的敌人

The concept that older people can join the military and get a second chance at life is fascinating. I wonder what inspired this twist on the usual sci-fi tropes.

The story raises questions about morality in war and expansion, but I kept wondering if I was supposed to sympathize or question the protagonists' choices.

This choice added depth and humor, but also made me think about the themes of age, vitality, and societal value. Was this a commentary on aging or just a fresh perspective?
