The Irregular at Magic High School Novel Volume 23 is written by Tsutomu Satou with illustrations by Kana Ishida.

Watching the news has been rather unpleasant for Tatsuya lately. It seems like whenever he tunes in, it's just one bad story after another. Just as he feared, it was only a matter of time before strategic magic was used again—this time by the Great Asian Alliance. Things hit much closer to home when a spell Tatsuya developed for the Nine School Competition years ago is tied to a brutal guerilla attack against GAA forces. These violent events only fan the flames of anti-magician sentiment, and it isn't long before rising tensions provoke a response, culminating in the announcement of the Dione Project, an ambitious plan to develop Venus with magic. While Tatsuya has his doubts about the new space program's true goal, this problem is about to get very personal when Taurus Silver is named as a prime candidate!
