The completion drop-off

The scale is logarithmic: each labelled gridline is ten times rarer than the one above it. On a linear axis the bottom thirty rows all collapse onto the baseline, which is exactly the part of the curve worth reading.

First-party evidence

The Nushi roster, read off the shipped game

Seven internal ids begin ACH_NUSHI_. Six display names take the form “…’s End”. Both counts come straight out of the snapshot below, so the arithmetic is checkable without trusting this page.

This matters because of what it is not. Every other boss list for this game is either an extraction of a pre-release engine asset or somebody typing what they heard in a video. The achievement manifest is the shipped game’s own table, served by Valve. It is the closest thing to a primary source anyone covering this game has — and it puts the internal id and the localised name side by side in one place.

Internal idDisplay nameAnimal named by the idHow it was paired
ACH_NUSHI_SHIKARangifer's EndDeer — 鹿 (shika)confirmed
Unique unlock percentage on both Steam endpoints, so the id and the display name were paired by the sync script without judgement. Rangifer is the reindeer genus.
ACH_NUSHI_SALAMANDERLacerta's EndSalamanderconfirmed
Unique unlock percentage on both endpoints. Lacerta is the lizard genus.
ACH_NUSHI_USHITaurus's EndOx — 牛 (ushi)confirmed
Unique unlock percentage on both endpoints. Taurus is the bull.
ACH_NUSHI_CROWCorvus's EndCrowconfirmed
Unique unlock percentage on both endpoints. Corvus is the crow genus.
ACH_NUSHI_KUMAUrsa's EndBear — 熊 (kuma)inferred
Tied on percentage with four unrelated achievements, so the mechanical join declined it. Paired by the animal-to-Latin rule the four confirmed rows establish: kuma is a bear, Ursa is the bear.
ACH_NUSHI_WILD_BOARErymanth's EndWild boarinferred
Same tie, same rule. Erymanth is the Erymanthian Boar of the fourth labour of Heracles — the only boar in the naming scheme.
ACH_NUSHI_KUno name could be attachedNot establishedunplaced
A seventh Nushi id with no sixth-plus display name left to attach it to. It is not the dog: Koo’s own achievement is ACH_WITH_KUU, spelled with two Us. Published unplaced until a display name can be tied to it.

What this does not establish

Not the boss order. Unlock rates fall as you go down a critical path, so the ladder is consistent with the story order — but a low rate equally describes an optional boss most players skip. Nothing in the manifest separates the two, so no order is published here. Not a complete roster either: 7 ids against 6 names means at least one Nushi’s achievement is not named “…’s End”, and we cannot say which.

Method

How the two halves were joined

Neither Steam endpoint carries both the internal id and the display name. Putting them together is the useful part of this page and the only place it could quietly go wrong, so the rule is published with it.

Strategy: unique-percentage21 resolved25 unresolved

The two endpoints disagreed on at least one position, so the positional pairing was discarded. An internal id is attached only where its percentage is unique in both payloads; every remaining achievement is published without one.

The sync tries a positional pairing first and checks it: if every position agrees on its percentage across both endpoints, the two lists are the same ordering of the same data and the ids are correct. If any position disagrees, the whole positional pairing is discarded rather than patched, and an id is attached only where its percentage is unique on both sides. Everything left over ships without one.

Beast of Reincarnation achievement FAQ

No. Unlock rates fall as you go down a critical path, so the ladder is consistent with the story order — but a low rate equally describes an optional boss most players skip. Nothing in the manifest distinguishes the two, and no order is published here.
