Shiba Miyuki was chosen as the Yotsuba heir during the clan's New Years gathering. Under Maya's order, news concerning the new heir is spread to the 28 families participating to the 10 Master Clans selection event. The Ichijou clan immediately objected to the engagement between Tatsuya and Miyuki; filling an official application to engage her to Masaki instead. Koichi talks with Ichijou's father and he is planning on wedding Tatsuya to Mayumi to weaken the Yotsuba's power.
1st Magic High School, Tatsuya and Miyuki's non-sibling relationship and engagement are now public knowledge. Among the shocked students the most shocked is Honoka. Mikihiko and Mizuki also behave awkwardly in front of the Shibas. Overall, the students pretend to ignore the news while in fact distancing themselves from Tatsuya and Miyuki.
Meanwhile, the 10MC selection meeting, followed by magicians all over the world, takes place at a hotel in Hokone. During this new 10MC selection, which is contended by the most distinguished magic families, a battle of wisdom and resourcefulness unfolds among the, Saegusa, Yotsuba and Kudou clans which check each other's power balance. The new 10MC families will be chosen as a result of this 2 days meeting . Suddenly a mysterious explosion strikes at the meeting place. It's a suicide bomb (performed by a magician). As a consequences of that many lives of unrelated (to the meeting) guests are taken. The mastermind of this terrorist attack is that "wise man"...
The anti-magic movement which originated with this act of terrorism is intensifying. USNA's strongest magic force is once again mobilized. Major Benjamin Canopus, the first commanding officer of USNA's magic squadron Stars, assists the general commander, Angelina Sirius. He's the number 2 of the Stars. Canopus' participation will have big consequences....!
