I decided that since the Massacre Arc is such a long, progressive one that tends to take its time developing (as well as noting that it’s the longest arc of the series I’ve watched thus far), I’m going to just go ahead and summarize the events of the arc and my thoughts about it without going into too much detail. Overall, I thought this was a great arc , but it took its fair time developing, and while I could break this down into pairs, it’s progression is far too sluggish to simply break it up, a lot of the episodes revolve around the same thematics, all culminating to one goal. Yet, like previous arcs, it does juggle negative events with ambitious pursuit.
Satoko is the central focus of this arc for quite some time-and if you remember the previous series-she’s victim to her abusive uncle. This particular arc does not go the same route as the previous however, and ties into the previous episodes in terms of the importance of changing fate. What I liked about it-it showed each of the characters taking a proactive role, and even showed Rika a bit more in terms of her gradual change to the optimistic. Of course, it also shows quite a bit of the characters in their “freak out” statures, running dangerously close to breaking point. Yet…as you can probably tell without even reading further into spoilers, there’s another story yet to be told-it also reveals a rather unlikely villain this time around.
It also marks the first time that Rika explains the Hinamizawa Syndrome in full respect-and makes the events that supposedly occur in the “volcanic disaster” make a lot more sense. Let’s say that Rika is similar to a “queen bee”-and if the “queen bee” dies…everything falls out of place.
Reflections of the arc under the cut. Instead of doing episode by episode screenshots, I included various collection of caps. Some episodes may not be represented in these caps, but I did my best to be inclusive enough to give a general idea of the events and also give something different that other anime blogs may not have covered with this series. I did end up changing fansub groups with respect to watching the remainder of the episodes, for the sake of completion.
Please, please don’t read unless you’ve seen the whole arc, because I’m not marking spoilers under the cut-it’s more collective.
Summarizing the Massacre Arc in an abbreviated context, particularly since I wanted to keep this entry minimalistic in description, and more on reflection.
Stating that, let me start off with the star of this arc-Keiichi. For a long time, even from the first series, Kei-chan was my favorite character alongside Shion (who had such a sense of passion despite being a complete murderess in the first series) and Rena. As shown in the previous episodes, Kei and the others had started to remember certain things about their pasts, in the other worlds in which they lived before Rika and Hanyuu jumped worlds. It becomes apparent that Rika and Hanyuu follow each other through each senario and the time gap between jumping gets shorter with each period. In this particular arc, when Satoko faces abuse from her uncle-Kei can’t stand back and do nothing. He tells Rika not to resign to fate and that it can be changed, something that proves important as the arc continues forward.
Satoko moves back in with her uncle, and is absent for three days from school-despite all efforts of the gang to tell of the abuse Satoko suffers, they meet a hard bargain in several levels-which lasts over three different episodes distinctly. Granted, episode 8 shows it all-Rika freaking out at the fact that the yakuza sworn to protect her can’t move in to help Satoko, Shion’s freaking out in the classroom when none of the groups efforts in contacting child services work (pending other investigations, including Satoko’s denial that anything is wrong…which is pretty much out of fear of her uncle) and ending up breaking a chair over poor Kei’s head…I’m surprised that didn’t give a lasting concussion. Kei’s the one that tells Rika, initially, that they are driven against fate, but when the group effort fails, even he comes close to giving up-it takes the meaning of Rika’s tears and pleading with him to help Satoko to knock him back to his senses.
Rika, Kei and Co opened the appeal for aid not only from their classmates and teachers, but also the roots of people in their community. Calls were made to Satoko’s uncle, and it’s inferred that he made Satoko return to school in episode 9 and instilled in her the excuse she would return with. She makes herself tolerate and deny the problem because she waits for Satoshi, her “nii-nii” as she refers, to return. Satoko, notably freaks out while at school to the sound of heavy footsteps in the hallway, and has a rather disturbing episode. Keiichi and company decide to appeal directly, with a representation of three, to protective services. Yet movement is limited: for one, the council still has a gripe against Satokos family from the times of the dam war in Hinamizawa, a stark difference from how they treat Rika-and if you remember in the early episodes of this series, how Satoko was blatantly ignored on some occasions by people in the community. Kei’s warned by Ooishi-san to watch his back, because members of the community might move against him AND the cause if he “presses” it too far. Episode 10 took it all the way up to the level of the Shinozaki household-meaning Mion and Shion’s own grandmother. Fortunately, she finally relents and gives Kei the power to “do what he wants” 
The plot movement in episodes 8-10 actually bugged me a little, despite how sound it was in communicating the efforts of Rika, Keiichi, and Co. moving to help Satoko in the face of her uncles abuse. Quite a few people may not necessarily appreciate how well done the plot’s constructed to show their fight against fate, but ultimately, it’s all worth it, as Satoko finally admits to her uncle’s abuse, and he gets what’s coming to him with the police forces who move in. Yay!
The problem now…it’s only a few days before the Watanagashi, and Rika’s life has been threatened. It doesn’t take long before her friends realize that Rika’s now the one in danger, and episode 12, in brief, is the one that opens eyes to many things…number one, the Hinamizawa Syndrome and how Rika acts as a protective queen bee-when she dies, the protective effect wears off. Furthermore, we find out Takano’s behind all the madness that ensues-suffice to say I didn’t really see her coming-but it makes sense since her time of death was off, even from the first series. Tragically, despite all of the efforts Kei, Rika, and crew show, they end up dying by Takano’s hand. 
In short: this was a great arc, and considering in the next few episodes, we’ll learn a bit about Takano’s past, it might shed some light as to how she went mad in the first place.
