I'm not confidence translating the spoiler but from I got
Spoiler for maybe wrong but yeah, it's hard:
- New Soviet invaded Sado again, they even deployed Tumba Bomba. In order to defuse the Tumba Bomba, Gouki had to handle but in exchange, he had to admitted to hospital, the one nursing him was Yuuka (not sure it's Tsukuba Yuuka or not, because I don't know how Yuuka written)
- New Soviet had more than 10 SC Magician (apparently cloning).
- 101 Magic Equipment Battalion had to distance themselves around Tatsuya because of their position (each other position, you know 10MC cannot directly interfere with Army and vice versa)
- USNA reboot their plan to capture SCM wielder. Silvia dispatched to Japan.
- At north sea (don't know how read it correctly), New Soviet clashing with Japan navy. New Soviet retreated due to their Tumba Bomba failed because of Tatsuya's Gram Dispersion, it became known to them about Gram Dispersion magic.
- Not sure how to read it, from I got, Tatsuya being investigated.
- Shiba sibling was ordered to come back by Maya.
- As Kudou clan planning to be 10MC once more, they're befriend with Yotsuba
- Kouchi met Shiba sibling (this incomplete from spoiler)
- In Young 10MC magician gathering, Saegusa first son made a proposal with "make Miyuki an idol" in order to appease common people hatred toward 10MC. (I cannot read the rest which explain Tatsuya's stance and how other families perceived it).
- Edward Clark (Raymond's father?) was the developer Hjskalif. In the meeting he was sure with Tatsuya's isolation (not sure what it means), so he made plan to neutralize or capturing Tatsuya
Again, I actually having hard time to decipher the spoiler. If this actual line from novel, maybe I could read but apparently this is from fellow reader.
