Touhou Koumakyou New Classic All 24 Steam achievements explained

Touhou Koumakyou New Classic ships 24 Steam achievements. Some are story natural clear conditions; others require specific shot types, difficulties, or Challenge Mode farming. This page lists every entry with conditions you can act on, an unlock order that prevents wasted runs, and notes on the tricky ones.

How to read this list

Achievements are grouped by type: story clears, shot-specific clears, spell captures, Challenge Mode milestones, and collection tasks. The unlock order column is a recommendation, not a rigid sequence. The game does not enforce an order; this column helps you avoid earning an achievement on a run that then prevents a harder one on the same credit.

Challenge Mode makes a large portion of this list easier because unlimited lives let you practice full fights without a deathbomb budget. Use it for milestone achievements before attempting limited-life credits.

Normal 1cc run for achievement reference

Story clears (6 achievements)

These six are the base clear conditions. They are the spine of the achievement list.

Achievement	Condition	Difficulty	Notes
The End of Winter	Clear Easy	Easy	Ends at Stage 5. Remilia not required.
A Certain Magic Weapon	Clear Normal	Normal	Standard 1CC. Opens shot-specific achievements.
The Grimoire of the Scarlet Devil	Clear Hard	Hard	Adds more spell cards per boss.
The Unreachable Night	Clear Lunatic	Lunatic	The skill ceiling. Most players stop here.
You and I Are Bound	1CC with Reimu	Any	Story clear; shot is locked at the menu before Stage 1.
A Little Magical Research	1CC with Marisa	Any	Same as above with Marisa.

The shot-specific achievements (You and I Are Bound and A Little Magical Research) unlock on any difficulty 1CC with that character. They are not separate runs if you are already going for a Normal 1CC — pick the shot at the menu and the achievement fires when you beat Remilia.

Shot-specific clears (4 achievements)

Achievement	Condition	Difficulty	Notes
Spirit Sign — Fantasy Seal	Clear with Reimu A	Any	Homing / Fantasy Seal. Most forgiving for beginners.
Divine Spirit «Fantasy Seal»	Clear Lunatic with Reimu A	Lunatic	The hardest individual achievement.
Magic Sign — Stardust Reverie	Clear with Marisa A	Any	Missiles / Stardust Reverie. Faster boss kills.
Magic Sign «Stardust Reverie»	Clear Lunatic with Marisa A	Lunatic	Same as above, Lunatic only.

Divine Spirit «Fantasy Seal» and Magic Sign «Stardust Reverie» are the two hardest achievements in the set. You need a Lunatic 1CC with Reimu A or Marisa A respectively. Do not attempt these until you can comfortably 1CC Normal with that shot. Challenge Mode on Lunatic before the credit. Spell Practice the cards that killed you on Normal.

Spell card captures (6 achievements)

Achievement	Condition	Difficulty	Notes
Spell Card Apprentice	Capture 10 spell cards	Any	Spell Practice counts. Do not need to capture in story.
Spell Card Expert	Capture 30 spell cards	Any	Total across all runs. Farm in Spell Practice.
Spell Card Master	Capture all spell cards	Any	Requires Hard or Lunatic for the extra cards.
Extra Stage Cleared	Clear Extra Stage	Extra	Unlock by 1CC Normal no-continue first.
Sister’s Seal	Capture Flandre’s last spell	Extra	Q.E.D. must be captured, not timed out.
The Sealed Scarlet Devil	Capture every spell card in the game	Any	Hard/Lunatic spell sets required.

The Sealed Scarlet Devil is the longest grind. It requires capturing every spell card in the game, which on Hard and Lunatic includes spell lists not present on lower difficulties. The fastest path is Spell Practice all cards on Hard first, then use a Hard 1CC to cover the remaining cards in one run.

Sister’s Seal is straightforward once you reach Extra: capture Q.E.D. rather than timing it out. Reimu B and Marisa A are common picks because point-blank range makes needle and missile patterns easier to capture than homing amulets.

Challenge Mode milestones (4 achievements)

Achievement	Condition	Difficulty	Notes
First Run	Complete any stage in Challenge Mode	Any	Tutorial unlock. Happens naturally.
Extra Practice	Clear any stage in Challenge Mode with no deaths	Any	Punish-free practice run.
Unlimited Problems	Clear all six stages in Challenge Mode	Any	Does not unlock Extra. Separate from 1CC.
100% Challenge	Clear all six stages with no deaths in Challenge Mode	Any	Requires a perfect Challenge run.

100% Challenge is a separate tracking milestone from a story 1CC. It asks for six stages with zero deaths in Challenge Mode. Use the death counter as your progress metric; do not confuse this with a 1CC.

Collection and miscellaneous (4 achievements)

Achievement	Condition	Difficulty	Notes
Power Lead	Collect 128 power items	Any	Happens naturally in normal play.
Graze Counter	Graze 1000 bullets in one credit	Any	Graze farming in Challenge Mode helps.
Overwhelming Victory	Beat Remilia with 20+ lives remaining	Any	Requires a dominant Normal or higher run.
Spell Card Overload	Use 100 bombs in a single credit	Any	Challenge Mode farming works.

Overwhelming Victory is the rarest in this group. Getting 20+ lives to Remilia on Normal or higher means hitting most extends (10, 20, 40, 60 million) and not dying. This is a score-run byproduct, not a separate achievement farm.

13. Divine Spirit «Fantasy Seal» or Magic Sign «Stardust Reverie» — Lunatic 1CC with target shot.
14. Spell Card Master — remaining spell cards.
15. The Sealed Scarlet Devil — full capture on Hard/Lunatic.
16. 100% Challenge — perfect Challenge Mode run last.

Challenge Mode versus story credits

The key insight: many achievements are easier in Challenge Mode (spell captures, graze, bombs) but story clears and shot-specific achievements require limited-life credits. Plan separate runs for each category. Use Spell Practice for card captures regardless of mode; it is faster and does not waste a credit run.

For spell card farming, open Spell Practice on a card, capture it, and repeat. The achievement counter tracks total captures, not the mode you used. Spell Practice is the fastest path to Spell Card Master and The Sealed Scarlet Devil.

Difficulty achievements stack: a Lunatic 1CC with Reimu A also unlocks The Unreachable Night, You and I Are Bound, and Spirit Sign — Fantasy Seal in the same run. Plan your shot before starting the credit, not after.

Notes on specific achievements

The Sealed Scarlet Devil requires every named spell card in the game. On Easy and Normal, bosses have fewer spells. Hard and Lunatic add cards to Patchouli, Sakuya, Remilia, and Flandre. You cannot earn this on Easy or Normal alone.

Sister’s Seal specifically asks for Q.E.D. capture. Timing it out does not count. Bring a shot type that can sit under Flandre at close range; Reimu B’s needles or Marisa A’s missiles work better than homing amulets here.

100% Challenge is independent of story progress. You can earn it before unlocking Extra, and it does not affect Extra unlock. It is purely a Challenge Mode tracking achievement.

Full spell card lists are on spell cards. Shot comparisons are on the shot type ranking. A practice planner is under practice.
