Nushi bosses — the verified kill funnel

The seven Nushi checkpoints below are not copied from a wiki: they come from two independent evidence chains that agree. The Steam achievement api ids name each beast in Japanese (shika = deer, ushi = bull, kuma = bear), and Game8’s launch-day boss table names them in Latin (Rangifer, Taurus, Ursa). Where both point at the same animal, the identification is corroborated. Kill percentages are live Steam data (snapshot 2026-08-04) — a difficulty curve nobody can fake.

Weaknesses and skill rewards are currently single-source (Game8) and labeled community-reported until players confirm them. Confirm or correct one and get credited.

1. Rangifer's End ✓ corroborated

Rangifer — the great deer (api id: shika, 鹿)

Beaten by

12.1% of launch-day players

The first Nushi and the first real wall: on launch day only about one in eight players had beaten it. Fought more than once across the story (chapter 1 encounters at level 9 and 12, and again at level 32 later).

Weak to fire. Rewards the Nushi Skill "Sakura Storm" and unlocks the Sakura skill line. community-reported
Game8 boss table; GamesRadar's Rangifer guide agrees on the fight, weakness pending wider confirmation
Parry economy wins this fight: successful parries refill Koo's FP, build the Down Gauge, and charge Emma's Blade Arts — three currencies from one input. Learn it here. ✓ corroborated
Game8 beginner guide, GamerFuzion and PixelNitro all describe the same parry economy

2. Lacerta's End ✓ corroborated

Lacerta — the salamander (api id: salamander)

Beaten by

3.1% of launch-day players

Chapter 2's closing Nushi (encounters reported at levels 13 and 16). The funnel drops hard here: only a quarter of the players who beat Rangifer have beaten Lacerta.

Weak to lightning. Rewards the Nushi Skill "Dokuzeri Shower" and the Dokuzeri skill line. community-reported

6. Erymanth's End ✓ corroborated

1% of launch-day players

Chapter 12 Nushi (reported level 47), late in the funnel.

7. Koo de Grâce unconfirmed

Unidentified (api id: ku) — we have not confirmed which beast this is

Beaten by

1% of launch-day players

The seventh Nushi checkpoint in the achievement data. The api id says "ku"; the display name puns on Koo. We have not matched it to a boss in any credible source yet, and we would rather say that than guess.

No credible strategy data yet — we’d rather say that than invent one. Beat it? Tell us how.

Non-Nushi bosses reported by Game8

Game8’s boss table also lists Nue Malefact (ch. 1/3/6, weak to poison), Shidou and Nue (ch. 3/6/11, poison), Kunai and Kirin (ch. 8/12, poison), Crimson Malefact (ch. 9, water), Door Golem (ch. 1 side boss, binding/acid), and the final boss. community-reported These match hidden achievement names we can see in the Steam data (Shidou & Nue, Kunai & Kirin), which is a good sign, but chapter/level details are single-source for now.
