- Description from novelbuddy

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.

One chapter was bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, with all of them together being equivalent to a single normal Toaru Majutsu no Index volume

A skilled thief gets a system in an Alternate Wizarding World. The system seems useless in the beginning since he hasn’t unlocked any features. But…

[The very first feature of the System has been unlocked.]

[Congratulations. You’ve unlocked the class feature. Due to your existing skills and experience, you have gained the Special Class "Arcane Thief" as your starting class. There’s nothing an Arcane Thief can’t steal. The more you steal, the more your Class will progress.]

[The fields of expertise include:

— Stealth Magic
— Wards
— Traps
— Enchantment
— Pickpocketing
— Knife/Short-Sword Wielding]

Wait…this is just the first feature?

Jianghu was in turmoil, an era of great strife. The leader of Great Qin wielded the Mo Blade, leaving the world battered and bruised. The ageless figures of Jianghu crouched upon the mountains, and with a single turn, they cast the entire world below them. Strong men measured the earth with their feet, and heroes of Jianghu could cleave the heavens with one sword, yet in the blink of an eye, they were drunk in the embrace of beauties. The Taoist carried his sword, the Scholar drunk on wine. Wearing tattered clothes, a beggar grasped a rotten branch and dared to storm the ancestral hall of the Taoist Sect. On the willow-lined causeway, in the long pavilion, a man who had sat withered for thirty years turned and stepped out, holding a peach blossom, with a flick of his wrist, he shattered ten miles of red candles. The era of Great Qin was renamed the Great Yuan Era. The youth with the Wooden Sword left his mountain village behind.
