Shin Megami Tensei V: Vengeance

=== Setting and characters ===
The events of Shin Megami Tensei V are divided between two settings: modern-day Tokyo and a post-apocalyptic landscape called Da'at. Da'at was originally an alternate version of Tokyo destroyed in a war between the Angels, who follow the Creator, and the demons, who are loyal to the fallen angel Lucifer. Before the game's opening, Lucifer kills the Creator, triggering a power vacuum where other deities, robbed of their Knowledge by the Creator, seek to regain it and ascend the Throne of Creation. The Bethel Organization, an alliance of polytheistic divine beings and human operatives from across the world, protects the real world from Da'at's influence. With Vengeance, the story splits into two branches: the "Canon of Creation", which is the original storyline, and the "Canon of Vengeance" with altered events. The storyline is influenced by in-game dialogue choices.
The game's silent protagonist is a high school student who is drawn into Da'at, and through fusion with the artificial Proto-Fiend Aogami, becomes the Nahobino, a demon-like being who has regained their divine Knowledge. Multiple supporting characters represent the game's moral alignments: the friendly but dim-witted Ichiro Dazai represents "Law", Bethel agent Yuzuru Atsuta represents "Chaos", while the rogue Shohei Yakumo and his demon companion Nüwa represent "Neutrality".
Supporting characters include Tao Isonokami, Bethel's mystical Saint; Yuzuru's shy younger sister, Miyazu Atsuta; and Sahori Itsukishima, a bullied fellow student. Supernatural representatives are the angel Abdiel, who remains devoted to the Creator, Hayao Koshimizu, Bethel Japan's leader, and the human form of Tsukuyomi, and Lahmu, an antagonistic fallen deity. Vengeance adds Yoko Hiromine, an independent Saint; the Qadištu, a group of female demons composed of Naamah, Eisheth, Agrat, and their leader Lilith: and the angel Mastema.

Plot

Coming home from school one day, the protagonist and Dazai are pulled into Da'at, where Aogami saves the protagonist from a demon attack by merging with him, becoming a Nahobino. After escaping from Da'at and returning to Tokyo, he and Dazai are met by Yuzuru, who, together with Koshimizu, recruits them into Bethel, where they keep demons from leaving Da'at. The protagonist learns the current version of Tokyo is not the true one, but a copy generated by the Creator when the real Tokyo was swallowed by a supernatural phenomenon, becoming Da'at.
During an attack on the protagonist's school, Miyazu is briefly kidnapped, and Sahori is influenced by Lahmu into killing her bullies and becoming its Nahobino. The protagonist is mortally wounded by Lahmu, but Tao sacrifices herself to revive the protagonist, who then kills Lahmu and Sahori. The protagonist then travels to Chiyoda and kills the leader of the demons, Arioch. During these conflicts, the protagonist frequently crosses paths with Yakumo and Nüwa, who seek to destroy the Throne of Creation and allow humanity to control their future. Afterward, at a meeting with Bethel's branch leader, the Nahobino is revealed to be an existence forbidden by the Creator. Abdiel is defeated when she attacks the protagonist while denying the Creator's death. The other deities, including Koshimizu, dissolve Bethel to recover their Knowledge and ascend the Throne of Creation. Tao is reborn as a goddess who will lead a Nahobino to the Throne of Creation, choosing to guide the protagonist when the false Tokyo collapses and Da'at overwhelms reality. In parallel, Yuzuru unites with Koshimizu to restore the prominence of all deities despite inevitable conflict, while Dazai convinces Abdiel to merge with him and create a conforming world of peace in the Creator's name.
The protagonist gains keys from the former Bethel deities to access the Temple of Eternity, which holds the Throne of Creation. At this point, the protagonist can side with either Dazai or Yuzuru or agree with Yakumo's goal to destroy the Throne; the latter choice causes Tao to abandon him. Regardless of choice, all the other candidates are killed, and the protagonist ascends to the Throne. If the protagonist completes certain side missions and sides with Yakumo, Nüwa reveals an alternate possibility of using the Throne to create a world free of gods and demons, which Tao is willing to support. In all but the ending where the Throne is destroyed, Lucifer grants his Knowledge to the protagonist in a final battle so the new world will potentially be everlasting.
In the Vengeance storyline, Yoko accompanies the protagonist for much of their journey, and the Qadištu interfere with events while gathering power to awaken the goddess Tiamat, whose overthrow by Marduk led to the Throne of Creation's role in managing the world. Sahori falls to an attack by Lilith, Miyazu is briefly kidnapped by Eisheth before finding sanctuary with a sympathetic demon, while Mastema blesses Dazai to fight within Da'at after Agrat spreads a plague of agony. The Qadištu succeed in gathering the required energy and completing Tiamat's summoning by sacrificing the protagonist and themselves. Tiamat's awakening devastates Da'at and kills Nüwa. Tao and Aogami sacrifice themselves to save the protagonist, and Yoko awakens as a goddess carrying Lilith's will to destroy and remake the world free of ruling gods.
In the aftermath, Dazai and Abdiel kill Yuzuru, and Koshimizu merges with the protagonist to restore his Nahobino form. Tao, in her goddess form, guides the protagonist to the Temple of Eternity, seeking to restore and preserve the world while granting everyone a chance at happiness. On the way, he is forced to kill Dazai and Abdiel. Depending on the protagonist's choices during the game, he sides with either Tao or Yoko to support their respective goals. In both routes, Tiamat attacks either at Yoko's or Mastema's command. Aogami is freed from Tiamat and reunites with the protagonist to defeat her, while Koshimizu dies saving the chosen heroine. After a final fight, either with the primal Tehom in Tao's route or Mastema in Yoko's route, the protagonist creates a new world with Lucifer granting his Knowledge as before.
