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 villainess known by all as a wicked woman who has done all sorts of evil deeds—Ducal Lady Violet.
She regained her memories of her previous life after she fell into a lake and almost died.
The very moment she woke up, she immediately visited her father, Duke Everett, and asked one thing.

“Please confine me to the annex.”

And so, she imprisoned herself there.
Now that Violet was secluded away from the world’s criticism and reproach,
She immersed herself in her previous life’s memories and started painting them.

“What the hell are you up to this time?”

Everyone was suspicious of just what she might be scheming.
However, the misunderstandings surrounding her gradually got resolved one at a time…

In this world, Planet Earth had undergone great changes and humanity is faced with extreme danger. Luckily, humans have something called the Heaven Dao software.

Rude is a tank, known as the strongest in history. However, the Hero decided that his skills were worthless because he couldn’t do anything but take damage, and threw him out of the party. His cleric friend who trusted him followed him to the remote village that Rude was forced to return to.
