Finished watching Episodes 3-5 of
Owarimonogatari finishing up the Sodachi Lost arc.
This honestly might have been one of the most depressing arcs in Monogatari. As the question to discuss being how did Oikura know that Koyomi's parents were police officers. We once again see Ougi Oshino making an appearance to "help" him. As Hanekawa senses the danger that bringing Ougi along brings, she suggests for herself to come with Koyomi. This is more so to prevent Ougi from accompanying Koyomi further. Kind of a highlight that Ougi is up to something.
We learn from Koyomi that Oikura was taken in by her parents since they knew of the abuse she was given at home. The strange point is that Oikura was quiet as the three Araragi kids went about their days. The weirdest part that comes out of all of this is why would Oikura go back home? More than likely it could be Oikura seeing what a normal household was and what she thought was normal isn't actually normal. The strangest part is why was Sengoku the only one who remembered Oikura.
As we learn from Oikura, she was stunned at looking at the Araragi kids happy. It was for the first time that she realized what a normal family is supposed to be. The abuse she was dealing with was not normal. That is why she ran away. More likely she sought out that normal from her own family, but that never was meant to happen. Even worse, she was trapped in that house with no way to reach for help. She tried to get Koyomi to help her in 7th grade, but things didn't go as expected.
As we learn more about the situation from Oikura, she was abused by both of her parents. Her dad on the norm and from dealing all the abuse she received by her husband, Oikura's mother brought the same onto her. Eventually, the parents had the divorce which lead to Oikura living with her mom. As one can imagine, a single mom who was abused by her husband is now taking on the load of providing for her daughter. We hear disturbing things such as "Parents can't choose their kids." This directly implies that her mom didn't choose to have Oikura. Was this a situation forced upon by her husband and she was forced to bear with it?
It adds the point that while the mom isn't innocent of all this. You can imagine the pain how Oikura feels as her mother locks herself in her room. Essentially, Oikura takes care of her mother. Though she never left her room. Because her mother was still alive, they still had support from the government. Oikura didn't want her mother to live out of love. Much the opposite, she only cares for her to live so that she can survive. Compare this to Koyomi who has everything of a normal life.
So when Oikura went into high school she needed something to lash out against. After all she was miserable. All she can do to look back on was when Koyomi didn't help her back in 7th grade. She knows it isn't fair to blame him for what happened, but it was the only thing that kept her going. It comes back to the point when she thinks to herself, why can't she be happy?
One thing Hanekawa picked up is what really happened to Oikura's mother. Essentially, we learn how she locked herself in her own room. But why does Oikura think her mother is missing. We do know her mother never ate, assuming it is safe to say she killed herself via hunger suicide. The sad part is that her mom now became part of the trash and Oikura never realized it as those that cleaned their house took her mother's corpse away.
We get back to the type of character that Koyomi is. He always wants to take the burden, but here he wishes to accept Oikura's pain. He wants her to hate him because in doing she can move her hatred from herself to him. In many of the previous arcs, Koyomi is left wanting to save his relationship for those he cared about. But with Oikura this is impossible. There is no route where he is on the same good terms with Oikura because she is beyond miserable.
He learns from his failure in 7th grade. Instead of taking the knowledge that he did back then, he wants her to hate him. Redirecting that can now allow herself to love her. Sure, their friendship can't ever be much going forward, but at the very least Oikura can turn her life around. You can't be happy unless you love yourself. In that way, she can take the small steps of turning her life around.
She takes the news of her mother much better than one would expect when Koyomi tells her the news alone. Oddly, with news given as dreadful as this, you are left wondering why was happy starting at Koyomi? Simply put, them being alone reminded Oikura of the time she was tutoring him. It was true that despite the hate she may press on Koyomi now, she still views him as a dear friend. More than likely her first one.
As this arc wraps up, we are left wondering how all these events have played into motion since Ougi transferred into Koyomi's school. Their math teacher being on maturity leave which brought Oikura to come back to school. In a blink of an eye, Oikura is gone. Very likely that Ougi was involved for Tetsujo for being on leave. It feels like some events got pushed forward where more than likely by Ougi. Admittedly, seeing her being the first character to get under Hanekawa's skin was very interesting to see.
In speaking regarding Hanekawa, she mentions she will take a leave of absence, but will be seeing Meme Oshino during this trip. She definitely has something planned to help Koyomi down the line. Very curious what it is. The head match between Ougi and Hanekawa will be interesting to see. Also, given how much Oshino was slightly nervous regarding Hanekawa.
This wraps up the Oikura storyline very well. Very excited about what is next in store. Furthermore, how much Hanekawa's absence will play a part in it.
