The late comer to the summer party Owarimonogatari season 2 is the conclusion to the Monogatari anime series. It was a Two day event. Being honest this was a two day OVA. Its technically a OVA. Owarimonogatari season 2 is shorter than any of the other monogatari anime with a whopping 3 episodes.
So the first part continues after the last episode of Kyomimonogatari. Basically Kyomi is set to hell and meet Mayoi there. She is tasked with guiding him out of hell. It turns out all of this was planned by Gaen with the help of Tadatsuru (main bad guy from Tsukimonogatari) to extract Shinobu from him and making him human again. Before leaving hell he takes Mayoi with him back to earth and Tadatsuru tell him the name of the person who hired him to kill Kyomi which was Oshino Ougi.
hitagi rendezvous was basically Kyomi and Senjogehara going on a date. This half was mostly use to set up Ougi dark. The only good part to me was when Ougi enters Kyomi dream and they talk until he wakes up. Im glad they deiced to make Senjogehara have long hair again. Also she has a driver license so that was cool and interesting.
In Ougi dark the first half was Gaen, Kyomi, shinobu(in her kiss shot form) and Mayoi dissucssing plans on how to take out Ougi. Gaen decides to make Mayoi god of the shrine Nadeko once took over when she was possed by the snake in order to restore some kind of balence in that town. Gaen says he original plan was make Shinobu the god of that shrine but plans fell through when Nadeko got involved. Gaen then tells Kyomi Ougi's true identy and that he alone must stop her. It turns out Ougi is Kyomi. Ougi was created to judge Kyomi and all his deeds and actions. Kyomi now knowing this confronts Ougi in the old cram school from bakemonogatari where Oshino Meme was located. Once Kyomi reveals Ougi true identity the darkness shows up to take Ougi. Kyomi ends up saving Ougi and losing a arm in the process.While the darkness is still there waiting to take Ougi Oshino Meme shows up along with Hanekawa. Meme end up making the Darkness go away by acknowledging Ougi as his niece thus acknowledging her presence.
The whole series ends with Kyomi, Senjogehara and Hanekawa graduating High school and Kyomi telling Ougi (who is basically a ghost like oddity now) that no matter how much he change he still gonna be himself.
Hitagi Rendezvou was kinda boring being honest. Yes her interaction with Kyomi was nice but plot wise if it didn't help set up Ougi Dark i would have skipped it.
Mayoi had the most character development she seem more mature in this series. I like the fact that they decided to make Senjogehara have long hair her character seem the same as in other series. Mayori had the most development as a character in my opinion
Weird animation choices were made in this series but it still was good and to be expected from SHAFT
This was a nice conclusion to the series overall. Hanamonogatari is the True ending timeline wise but Owarimonogatri season 2 was a good ending overall. It wrapped up every loose ends nicely and it was good.
