Spoiler from "Wikia contributor 64.233.173.108" translated from baidu to English
Gu jie want to tell Japan that 10mc will only protect themselves, leave Japanese in the lurch, Japanese will, because of 10mc, be killed. 10mc and the yotsuba will be force out of their home by the hate of the Japanese, just like how he lost his homeland, dahan. He smiled and stood up. At his feet , lies a family of corpse
Benjamin was at the embassy during the attack he wanted to work with the Japan government to stop the attack but was not allowed. His mission is to kill heigu on the condition that there is no evidence of overreaching the Japan sovereignty.
After questioning, 10mc went to magician association kanto branch by helicopter from masaki arrival. Saegusa twins and eldest brother, Katsuto, Masaki and Takuma was also there in another room. 10mc hold another meeting.
Ichijou father wanted him to take leave from school to investigate but third high principal persuaded him to let masaki go first high.
Meeting between 10mc is quite long. They discussed their pr strategy and whether to catch the culprit. In the end, tomokazu is the head of the operation while kastuto is the person in charge. Both tatsuya and masaki is under kastuto.
Gouki told masaki the plan. He took leave from school so that masaki can investigate. He encouraged masaki to show his will to tatsuya.
Maya told tatsuya the plan. Maya knew about the name of gu jie. Maya says that they will use fortune telling to find him. (Tatsuya explain this by saying they might have use some form of psychometry or post cognition magician.) Maya regrets not using balance information fully.
It's quite likely that Masaki made to get closer to Miyuki is by transferring to First High for a period of a single month.
that 3rd high principal is a former military and one year senior of Ichijo, used to break his nose during sparing, so they are old friends, an interesting side character, there will be no problem because Masaki will be learning from the 3rd high material via teleconferencing, (except physic ed. and practical training.) only using the 1st high facility. we are after all talking only a time duration of one month, which of course including valentine's day.
After knowing who is the enemy, tatsuya went to Yakuno to counter ghostwalker. That night, he went to a meeting at Katsuto and Mayumi appeared surprisingly. They decided that the meetings are held everyday at a shop near magic university. Gu jie plan worked well. Even Kanon formed enemy with izumi. Takuma looked for Maki for help to stop the media as he feel responsible as a 10MC. Kuroba is able to use aura? To track people. Hence, he abet to a morgue to cast his tracking magic, to track gu Jie. Toshikazu and his partner went to find Kyoko.
Tatsuya, Katsuto and Mayumi had their first meeting. Tatsuya arrived at university gate 5 minutes early and mayumi escorted him to the shop. Tatsuya Sat beside mayumi and was opposite Katsuto. At this moment, he remembered Mari conversation, wondered he has any feelings for Mayumi. Tatsuya provided the USNA information. After the meeting, he escorted Mayumi to her ride. It started to snow, and Tatsuya covered mayumi with the umbrella, Mayumi then hold onto his hand all the way to the stop.
Kuroba found out Gu Jie place. All of the branch head and Tatsuya went to catch him. They didn't managed to catch him but found out that he was using enhanced people from the military. Toshikazu contacted Kyoko, then found out Inagaki was feeling unwell. Kyoko and 101's currently investigating Zhou incident. Shiba sibling was invited to Kitayama house. Shizuku father asked if they needed help, but was rejected by Tatsuya. If his family is involved, he will act upon it.
Koichi met with 上野 congressman and pressure him to stop secretly inciting the public. Masaki arrived at first high, same class as miyuki. Tatsuya then told him about the meeting. After the meeting, he went back home first, questioning whether Miyuki is acting differently recently. Maya called and he explained to her that the military might be hiding Gu Jie and reveal that Mayumi is in the meeting. Miyuki was very jealous.
During class, Miyuki was practicing with Masaki. Honoka asked masaki to have lunch together. (Might have the intention to couple up with Miyuki). At the lunch table, Tatsuya ,hearing the conversation, felt that love is like a war. After school, Tatsuya went to 101. He explained to Kazama about the military helping Gu Jie, and told him about Yotsuba attacking a base. He wished Kazama could pick up the pieces. When Tatsuya and Kuroba twins entered the base, they interrupted by USNA. USNA is able to get gu Jie Psion signature to track him down.
Valentine day arrived. Tatsuya receive a lot of chocolate. Returned home, miyuki have recently made chocolate for him.(not much)
Anti magic movement become bigger. 400-500 people gathered at magic university Gate. Inagaki head aches again, which worries Toshikazu. Under Maki help, Takuma allowed congressman to make an act, preventing the anti magic movement to stop rallying the people. Gu Jie felt anxious. Student started getting attacked. 2nd high girl student was attacked. Miyuki contacted minoru (vice president) to understand what happened.
Tatsuya warned Minami to be more alert and change the type of shield to use . Toshikazu met Erika whether she met inagaki. From Kyoko, inagaki headache might be from gu Jie manipulation. With Haruka help, they found him, lying down in a house. They then was ambushed and knocked out of consciousness.
Minami Miyuki Izumi got attacked by anti magician group with Psion interference, antinite. Both minami and izumi wasn't able to do anything. Miyuki apparently was able to do something about it. Toshikazu and inagaki is being manipulated by Gu Jie.
Tatsuya still see miyuki as a sister, still unable to respond to her feelings. But during Valentine, there is some "flashes" (scenes that show their love)
Tatsuya feels that miyuki might face some danger. However, tatsuya still went and investigate gu jie. He believes that miyuki can handle these people but if something happens. Then the book ended.
TA
When Katsuto was released from police questioning, the narrator provided interesting details regarding the Mahouka world. According to the narrator, the legal age for being adult was lowered to 18 years old, but it was increased to 20 years old in 2070s because many young people were enlisted to the army during the 20 years war, and they increased the legal age in the form of repent. Increasing legal age has been a global trend. In an extreme case, legal age for being adult dropped down to 16 years old and increased to 25 years.
Members and related people from other families could be seen, but the butler, Hanabishi (#3)'s men were trying to hide in order to avoid getting attention.
Miyuki asked about Saegusa Tomozuka (Tomokazu) because when Saegusa twins called their half-brother, Kasumi called him as "Aniki", and Izumi "Oniisan". And, they expresses some awkwardness while saying those words.
At the end of discussion about Miyuki's fear on police being influenced by Humanist faction, everyone decided to depart except Takuma. Before Tatsuya left the place, Takuma was about to share an opinion on the subject that Tatsuya and Miyuki were discussing, but Takuma restrained himself from sharing his opinion.
At the end of the chapter, Gu Jie was watching the tragic terror attack. He was at the mansion located in Odawara. It is located 9 km East from 10MC meeting place.
The first color page with Masaki and shocked Miyuki, Honoka, and Shizuku. Masaki: "I am Ichijou Masaki from 3rd High School. I will be studying together with you due to strong friendship (情, sentiment, heart, affection can be used.). It is short one month, but I am looking forward to it. (Direct translation of the last sentence is "Please look after me".)
The second color page with Honoka, Eimi, Subaru, and Shizuku
Shizuku: "This is for the friendship(義理). You don't have to give back envelope."
Subaru: "Ah, I also have it. I am sure you know it, but this is for the friendship (義理).
Eimi: "Me, too. Here, friendship(義理) Chocolate."
Honoka: "Please accept this."
(義理: in many cases, it is being used as "loyalty" or "fidelity". But, Friendship may be suitable for this case.)
4chan
Only Tatsuya and Erika are aware that Masaki loves Miyuki because they are perceptive about things like that. Miyuki can probably guess that he's into her at least. There's a conversation between Erika, Leo and Miki about Masaki and she points out that he's really into Miyuki. Miki and Leo seem a little shocked or surprised by him transferring. It's like the three of them are watching a drama and having popcorn about everything. Masaki interacts with them later.
Vol 19 will be released on spring, earliest will be february. May 20 we will get short story?
