Kyoko the Tomorrow

With only his eager assistant by his side, the leader of the demon world has arrived to seize control of the modern human world. Their initial attempt is met with skepticism as most mistake him for a mere cosplayer. Moreover, the demon world's recent economic turmoil has left him woefully underfunded. To achieve his ultimate goal, he must vanquish the human world's hero - Ichikawa Kyouko, a stunningly beautiful and resilient young woman who has been designated as the chosen one by wielding a colossal sword.
