No illustration, only 1/5 about Mitsuya Shiina, 4/5 about current upheaval because of the news
Spoiler below didn't include the timing and date, because *laziness*
Spoiler for preview vol 21:
1. At the morning after coming home from Okinawa, there was news about Brazil invoked their Strategic-Class Magic, "Synchroliner Fusion".
2. Brazil govt admitted easily about the usage, and stated the killed people about 1000.
Tatsuya only gritted his teeth and said to Miyuki, the death number should be more than that.
3. Tatsuya, Miyuki, and Minami came to school in order to prepare for School Entrance Ceremony. In the SC room, there were already Kasumi, Izumi, and Mitsuya Shiina.
Kasumi was a Mikihiko's deputy as PMC President.
4. Shiina seemed close with Kasumi and Izumi, maybe because their same situation, 10MC member and not a oldest daughter and about same age.
5. Shiina greeted Miyuki but she realized she didn't remove her headphone from her head. When she was going to apologize about that, Miyuki said she didn't mind and understand Shiina's circumstance.
6. Actually, it was not headphone but more like ear muff. Shiina had audio/noise hyper-sensitivity. It was like Midzuki but Midzuki was hyper-sensitive to pushion light while Shiina to physical noise.
7. Before going home, she gave her homemade snack (if I remember it was pancake?) to everyone.
8. Before meeting with Miyuki and Tatsuya, Shiina actually scared because she always heard from her sisters and brothers that Yotsuba clan a dangerous clan.
9. Honoka didn't come because she was fever as soon coming back from Okinawa.
10. The updated death number spiked to 12000 people when Tatsuya checked the news after lunch.
11. In response to news, the riot happened in USNA New Mexico, the army that supposed to hold that riot was West Guard (which personnel were magicians that failed to be Stars, not Stardust though).
12. In Germany, many protests happened by theirs students in response of the news.
Lastly, Prof. Schmidt was invited by McRoad to defect to Britain.
---------------------
In USNA riot case, actually there's scene where Silvia reporting it to Lina and various interpretation and the detailed of riot but I was too lazy to read it in detail.
Also when Tatsuya analyzing the usage of Synchroliner Fusion, there was detail of magic invocation, basically it was Pure Hydrogen Bomb.
I'm not sure why the name is MacLeod, I always thought it's McRoad
There are other details but if it's not about Tatsuya, I'm too lazy to read it
