MTL - Cultivating In Secret Beside A Demoness - Chapter 677 Swear to protect brother Ling Chen

A series of short stories in the world of Toaru Majutsu no Index organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.
