The Irregular at Magic High School, Vol. 26 (Light Novel): Invasion ARC

Parasites are taking over magicians left and right. Several of Lina's infected teammates make an attempt on her life, but after the rebellion at the Stars' headquarters, she successfully escapes. Thankfully, Tatsuya and Miyuki can give her refuge on Miyaki, an island controlled by the Yotsuba clan. They're not out of the woods yet, though, as everyone is eager to capture Lina for their own purposes. Meanwhile, Minoru--who has become a parasite himself--launches an assault on the hospital to kidnap Minami, and only the Saegusa sisters can stop him! The parasite invasion continues, pressure mounts, and magicians around the world prepare to clash. How will Tatsuya navigate this maelstrom?!
