Sekiro: Shadows Die Twice — Journal

Ashina Castle is the central hub area of the mid-game, accessed through the great gate after the death of Gyoubu Oniwa. It is a vertical fortress of tiled rooftops, sloped courtyards, and lantern-lined corridors built into the side of a mountain. The castle introduces the first stretch of the game where verticality and grapple traversal genuinely matter — much of it is navigated by hooking between rooftops, dropping into open windows, and stealth-Deathblowing patrolling samurai from above.

Ashina Outskirts is the first proper play area of the game, accessed from the Dilapidated Temple. It is a winding road of cliffside villages, abandoned checkpoints, and bombed-out fortifications that climbs from the valley floor up to the great gate of Ashina Castle. The Ministry's siege has begun in earnest: most of the soldiers patrolling the road wear the broad straw hats and red sashes of Ashina troops, but artillery, scattered corpses, and burned wagons make it clear the defense has been overrun in places.

The Blazing Bull is a mini-boss encountered in the lower courtyard of Ashina Castle, immediately after entering the area through the main gate. It is a massive bull with a flaming bundle of straw and metal lashed to its horns, kept in a fenced training pen by Ashina handlers. Its entire moveset is built around unpredictable horizontal charges that span the length of the arena.

The Chained Ogre is a mini-boss encountered partway up the road of Ashina Outskirts, restrained at the top of a stone staircase by two priests holding spiked rods to his neck. Killing the priests first is the recommended approach: doing so lets the player skip his throw-heavy opening phase by initiating a stealth Deathblow on him while he is still pinned.

Genichiro Ashina is the structural midpoint of Sekiro and is widely treated as the game's "skill check." He is fought on the rooftop of Ashina Castle's central keep, in a wide arena under heavy clouds, and the encounter is the first full duel against a humanoid swordsman with the player's full kit.

Gyoubu Masataka Oniwa is the first true main boss of Sekiro and is the gatekeeper between Ashina Outskirts and Ashina Castle. The fight takes place on a wide, flat field in front of the castle's gate — a deliberate change of arena scale from the cramped duels that precede it. Gyoubu fights mounted on a black horse, charges with a long spear, and announces himself with a famous shouted introduction that has become one of the most quoted lines in the game.

Hirata Estate is the first memory area of Sekiro — a flashback location accessed by offering the Young Lord's Bell Charm to the Buddha statue inside the Dilapidated Temple. The memory takes place years before the main game, during a night raid on the Hirata clan's mountain estate by the bandits of Juzou the Drunkard, and Wolf revisits the night as a one-armed shinobi remembering events when he still had both arms.

Juzou the Drunkard is a mini-boss encountered in a torchlit courtyard partway through Hirata Estate, surrounded by roughly a dozen bandit retainers. He is enormous — easily twice Wolf's height — wields a wide-bladed cleaver, and inflicts Poison buildup with a gourd of putrid alcohol that he periodically slings outward in an arc.

Kusabimaru is Wolf's katana and his only sword for the entire game — Sekiro has no weapon-swapping system the way other FromSoftware titles do. The blade was a gift from Kuro and is recovered by Wolf at the Dilapidated Temple after the prologue. Its name translates roughly to "wedge" or "linchpin," reflecting Kuro's intent that it bind Wolf to his service.

Lady Butterfly is the first major optional boss of the game, fought in a hidden temple beneath the lord's residence in Hirata Estate. She is an aged kunoichi who fights in flowing white robes, leaps between hanging streamers in the rafters, and uses an illusion-based moveset built around purple butterfly projectiles and shadow clones.

At the conclusion of the prologue, Genichiro severs Wolf's left arm at the elbow and leaves him for dead. Wolf regains consciousness in the Dilapidated Temple, a half-ruined sanctuary on a hillside outside Ashina Castle. He is now fitted with a strange wooden left arm — the Shinobi Prosthetic — by the Sculptor, a one-armed monk who maintains a workshop full of Buddha carvings inside the temple. Emma, a doctor in service to the Ashina clan, is also present and explains that Wolf has been brought back by the power of the Dragon's Heritage flowing through his pledged bond with Kuro: the Resurrection mechanic the player will use throughout the game.

Mushin Arts is the high-tier skill tree that unlocks after defeating Genichiro Ashina. Up until that fight, the player has had access to three skill trees — Shinobi, Prosthetic, and Ashina Arts — each containing combat arts, latent skills (passive bonuses), and a small number of texts. Mushin Arts is gated behind Genichiro because it represents the techniques Wolf is presumed to have learned by surpassing the head of the Ashina school.

The opening sequence places Wolf — the player character, a shinobi sworn to the Divine Heir Kuro — at the bottom of a dry well in Ashina territory. After a brief tutorial pursuing intruders through a moonlit garden, Wolf reaches the upper floor of the tower where Kuro is held captive. The encounter with Genichiro Ashina that follows is the game's first scripted boss fight and is unwinnable on a first attempt; it functions primarily as a cinematic establishment of the antagonist's skill and the protagonist's place in the world.

The Shinobi Prosthetic is the wooden left arm that the Sculptor fits to Wolf after the prologue. It functions as a permanent equipment slot rather than a consumable, and it is the slot into which all Prosthetic Tools — Shuriken Wheel, Flame Vent, Loaded Axe, Loaded Spear, Loaded Umbrella, Mist Raven, Sabimaru, Divine Abduction, Finger Whistle, and others — are installed.
