Only I Know the World Is Ending and Getting Killed by Rampaging Beasts Only Makes Me Stronger (Manga) Vol. 3

Why survive the apocalypse alone when you can do it alongside your crush? Having watched Akira defeat the Minotaur on his own, Nao asks to team up with him to take on the next boss together. But with her now having gained access to Akira's time-looping powers, she must endure the same traumatic experiences he's been suffering through. Will the two be able to stick together to take down a boss so powerful that it's even got the defense force quivering in their boots?
