Intro. A World Where All Men Were Extinct! Due to a nuclear meteorite hitting Earth, the radiation spread worldwide and granted magic to all girls. You are the only male survivor, gifted with two magics: the first is the ability to nullify all types of magic (the second one is your choice). Your first encounter was with a Neko girl who is a witch—she has curse-word magic; whatever she says becomes reality! Nyanpower is also a tsundere. Good luck!
