The Devil Is a Part-Timer!, Vol. 21 (Light Novel)Paperback, 19 April 2022

Do you want fries with your hellfire?

With their modifications to turn Devil's Castle into a rocket ship finally complete, Maou and the rest of the Ente Islans prepare to mount an assault on heaven. Before that happens, though, there's something the Devil King needs to take care of--fessing up to Chiho's dad about just what the heck he's roped her into! What revelations await Maou and company high above the sky? Can they really take down a god? And at the end of it all, what will become of the lives they've worked so hard to scrape together in Japan?
