Dead Dead Demon's Dededede Destruction Vol. 4 (manga)

It's just an everyday apocalypse.

Three years ago the aliens invaded Tokyo. Nothing was ever the same again. But after a while, even impending doom starts to feel ordinary.

Despite the ongoing menace of wild Invaders and A-ray contamination, people are still moving to Tokyo to find opportunities and themselves. After all, the likelihood of getting squashed by a crashing Invader vessel is still extremely low!

Meanwhile, Kadode and her friends have started university, where they must face the crisis of choosing which student club to join--a critical decision that will affect the rest of their lives!
