Tactics Ogre: Let Us Cling Together

Tactics Ogre takes place in Valeria, an archipelago united as a single kingdom under King Dolgare and worshipping a pantheon of six elemental gods, together with the Light Goddess Ishtar and the Chaos God Asmodeus. After Dolgare's apparent death with no direct heirs, the three primary ethnic groups of Valeria end up in a brief civil war, dividing into dedicated territories of varying sizes. The factions are Bacrum-Valeria, backed by the foreign nation of Lodis and ruled by its regent, Bishop Branta Mown; the Galgastan Kingdom led by Cardinal Barbatos; and the Walsta People led by Duke Ronway. After Galgastan gains the upper hand and declares itself ruler of Valeria, the neighbouring Walista are subjected to persecution and restricted to a small island.

The story opens with a small Walsta resistance group−Denim Powell, his sister Kachua, and his childhood friend Vice Bozek−attack a group of roaming Zenobian mercenaries falsely believing their leader Lans Hamilton is the Black Knight Lans Tartare, a Lodis soldier who imprisoned Denim and Kachua's father Plancy in their childhood. The sympathetic Hamilton joins the group, bringing the old sage Warren, and Kachua vainly attempts to dissuade Denim from fighting. Denim's loyalty to the resistance is tested when Ronway orders the massacre of a town that refuses to join them, framing Gargastan for the crime. Whether Denim agrees or refuses the order, Vice disagrees and opposes him.

If he rebels, Denim can later reconcile with Ronway or continue his own path. Following this Vice either becomes a fugitive for disagreeing with Denim's return, or secretly allies with Bacrum for his own ends as he serves Ronway. Eventually finding Plancy dying from a terminal illness, Plancy tells Denim he is of the Mown family, and Kachua is Dolgare's illegitimate daughter, giving her a direct claim to Valeria's throne. By this point, the revelations regarding their bloodline and the constant danger for Denim strain his relationship with Kachua, leading her to briefly join Tartare's forces.

If Denim does not comfort her, she commits suicide. Hamilton is captured and tortured by Tartare during this period, and while rescued Hamilton is left crippled and mentally traumatized. Gargastan is conquered and Barbatos dies either by suicide or execution. In all routes, Ronway's complicity in the massacre is revealed, leading to his assassination by his own people.

Tartare's forces are defeated and Denim kills Branta Mown. Survivors of Tartare's Dark Knights use the stolen Zenobian sword Brunhild to break the seal on a portal leading to the realm of Asmodeus, attempting to use its power to repel Denim's forces but are instead killed. It is revealed that Dolgare, overcome with despair over the death of his wife, made a pact with Asmodeus in an attempt to resurrect her and became an Ogre, one of humanity's ancient enemies. Dolgare attempts to return to reclaim Valeria, but Denim's forces defeat Dolgare and Warren sacrifices himself to seal the portal.

Depending on Denim's actions and Kachua's fate, either Kachua is crowned queen and unites the groups in a time of peace, or Denim is crowned king and either sees Valeria conquered by Lodis or is assassinated during his inaugural speech by a Gargastan. Vice's fate varies depending on the route, either surviving as Kachua's ally, dying after killing Ronway, or being executed by Bacrum-Valeria to protect Branta Mown. In all endings, Hamilton is left in Valeria, his surviving forces return to Zenobia with Brunhild, and Tartare escapes back to Lodis.
