Blue Archive the Animation Episode 12 Discussion

@LeonLanford Next seasons, depending on the order of adaptation, would focus on Millenium for Vol 2, Trinity, Gehenna and Arius for Vol 3 and SRT and Valkyrie for Vol 4.
Abydoss will only be mentioned in Vol 3 due to Hifumi's actions coming after her.

I'm answering this so you get the knowledge, but the anime should have been the one to explain the bare minimum and it failed.

First paragraph is answered in the prologue, which the studio seemed to deem unnecessary and only showed a still frame in chapter 2, ruining a lot of introductions for anime onlies.

• Sensei is the player, there's no more to it. Blue archive is very meta in some things, there's also a shit ton of references at things like whaling to the point that sensei uses his credit card during some moments in different parts of the story, which result in the only times in the story you are able to use custom teams instead of the given by the story.
  
  
  There's also your corrupted self from a failed timeline expending pyroxenes (premium currency) to revive and buff Shiroko Terror during his boss fight
  
  
• Both sensei and the members of Gematria come from outside of Kivotos. This makes sense since you, the player, are entering the game world from our world.
  
• Schale is a special department created by the general student council president with extrajudicial powers with the intention of it to mediate between academies. Schale has the power to call to any student, any school at any moment and they have to answer to that duty above all else. But sensei doesn't abuse this.
  
• This was actually explained half-heartedly. Ayane had been sending request for supplies and help to the general student council for a while. In his first day in the office, sensei asked Arona what request were made that the general student council ignored, and he picked abydoss due to nobody looking at them.
  
• Arona tablet is a piece of ancient technology that only those who have clearance granted by another ancient artifact and know the activation key can use. The president left them to sensei before dissappearing and is the only reason he is not dead. The anime fails to portray it, but the tablet does more things than be cute and search on the internet.
  

The part about abydoss is Vol F territory.

• Buried in the abydoss deserts are some ancient technology weapons, vehicles and items. Kaiser knows that and wanted to take them.
  
• The school is the government of a district. By shutting down the school, Kaiser would become the de-facto ruler of the Abydoss autonomous region. This was explained in the anime.
  
• The experiments were a Gematria thing, not aligned with the school takedown planned by Kaiser.
  
• The explanation for this was released on JP server this month, can't answer it yet since haven't read it.
  
• Only a part (although growing) of Abydoss is desertified. The rest of the district is connected to the rest of Kivotos and get normal appliances.
  

Sensei's paragraph... well, their version of sensei is like that.
Doubt it counts to you, but overall in-game sensei tries to lecture the girls to differentiate good from bad, but will always choose the option that benefit the students. Also, as someone above the law due to his condition as director of Schale, he can pretty much get away with almost anything.

Hoshino's past was released this month in JP so can't answer that yet, but theoretically Yume is dead.

The halo... a contentious point since it hasn't been fully revealed.

• The halo above their head identifies them as natural residents of Kivotos. It confers them a generic above average resistance to almost anything from fatigue to damage, and acts as some kind of lifeline. If you ask me, the Halos are a result of ancient technology and related with the seven Konas in the sky.
  
• There are other entities apart from the girls that have Halos, but they don't appear in Vol 1.
  
• Yes, destroying a Halo kills a student. This will be brought in Vol 3 during Seia's assassination along with a detailed explanation of the most efficient ways to do so.
  

There's no much more about Schale. Is just an organization.
Imo the interesting parts are Gematria, the nameless priest and the Chroma.

People talking about Chroma and Nameless Priests in a volume 1 adaptation :MikaXD:

@CorbanEsp Thanks for the explanation, the overall plot is more clear to me now.

I'm interested in Schale because it seems sensei fought with other students too. So it's confirmed that sensei is problem solver from Schale with high authority right? Also the missing student council president made me curious too, I think sensei somewhat connected to them. I forgot about Gematria, nameless priest, Chroma, must have missed them.
