Touhou Project EoSD Guide: Characters, Mechanics, and New Classic

Overview

Touhou Project EoSD (Embodiment of Scarlet Devil) is the sixth entry in the series and the first released for Windows, establishing the foundation for the franchise's modern era. While official tier rankings do not exist, player choice centers on distinct character trade-offs: Reimu Hakurei offers a wide attack range and defensive stability, while Marisa Kirisame prioritizes concentrated firepower and speed. The 2026 release of Touhou Koumakyou: New Classic remasters the title with 1080p visuals, a fully rearranged soundtrack, and an infinite-lives mode, earning Overwhelmingly Positive reviews on Steam. This guide covers character mechanics, the unique rank system, difficulty quirks, and the remake's features.

Character Comparison and Shot Types

EoSD provides two playable characters, each with two shot types that define the gameplay loop. The official New Classic site describes Reimu as "hard to hit" with a wide attack range, whereas Marisa specializes in "high firepower." These descriptions align with the mechanical differences between the characters and their sub-weapons.

Reimu Hakurei Reimu's shots cover a wider area but deal less damage per projectile compared to Marisa. * Reimu A: Uses "Homing Amulets" that automatically track off-axis enemies. Her bomb, "Fantasy Seal" (Musō Fūin), excels at clearing basic enemies. * Reimu B: Switches to straight-firing "Persuasion Needles" and the "Evil-Sealing Circle" (Fūmarin) bomb. This configuration is often described as highly balanced and defensive.

Marisa Kirisame Marisa's shots have a thinner spread but trade coverage for speed and power, focusing damage on targets in front of the player. * Marisa A: Fires "Magic Missiles" and uses the "Stardust Reverie" bomb. This setup provides concentrated power against bosses but offers limited screen coverage. * Marisa B: Utilizes the penetrating "Illusion Laser" and the highly destructive "Master Spark" bomb.

The choice between characters affects spell card availability and optimal strategies. Reimu's homing shots can simplify point collection, while Marisa's lasers are effective for maintaining power against bosses.

Core Mechanics: Spell Cards and Item Get

EoSD introduced the Spell Card system, which remains a staple of the series. Bosses and minibosses execute attack phases denoted by named spell cards. Each card has a countdown timer; clearing the phase before time expires grants a point bonus. Players can achieve a "capture" by clearing a spell card without losing a life or using a bomb, which awards a further bonus. There are 64 spell cards in total, viewable in the "Score" menu after encounter. Depending on difficulty and shot type, certain cards may be swapped or skipped.

The "Item Get" mechanic allows players to collect all items on the screen by moving to the top of the display, provided the player is at full power. This screen-clearing collection method was retained in every subsequent Windows entry. Players can also graze bullets for points, with each narrow dodge awarding 500 points.

Rank System and Difficulty Scaling

A hidden "Rank" value, ranging from 0 to 32, dynamically adjusts the game's difficulty during a run. As the rank increases, bullet speed and density rise, particularly affecting boss attacks. The rank value increases over time and rises dramatically when players achieve spell card captures.

The rank system keeps runs tense by rewarding aggression while penalizing mistakes. If the player is hit, the rank drops by 16. This reduction applies even if the hit is survived via a "deathbomb" (using a bomb within the six-frame window after being hit to avoid losing a life). Some specific spell cards, such as "Water Elf," also decrease rank when bombed. Managing rank requires balancing point collection and spell card clears against the risk of taking damage.

Unique Quirks and Accessibility

EoSD retains the fast pacing of the PC-98 era titles, contributing to a reputation for heightened difficulty among Windows entries. One notable quirk is the hitbox visibility: EoSD is the only Windows game where the player's hitbox is not visible while in Focus Mode. Focus Mode slows the character's movement for precision dodging, but the lack of a visible hitbox in this state requires players to rely on muscle memory or external patches.

The game structure includes six stages plus an Extra stage. However, an accessibility quirk unique to EoSD blocks players on Easy difficulty from continuing past Stage 5. This restriction prevents accessing Stage 6 and the Extra stage on the lowest difficulty setting. Additionally, the deathbomb window shrinks each time the technique is successfully performed until the player loses a life, adding a layer of resource management to bomb usage.

Stage Structure and Extra Content

The main campaign consists of six stages leading to the Scarlet Devil Mansion. Completing the game unlocks the Extra stage, where the final boss is Flandre Scarlet. An exclusive Extra demo distributed through Japanese doujin shops featured a significantly harder final boss section compared to the retail version, showcasing ZUN's iterative design during development.

Touhou Koumakyou: New Classic Remake

Touhou Koumakyou: New Classic released on September 9, 2026, developed by Shanghai Alice Reprise and published by Alliance Arts. The remake remasters the game in 1080p and includes a fully rearranged soundtrack by ZUN. It introduces an infinite-lives mode, allowing players to experience the content without life constraints.

The release bundles two versions: * New Classic Version: Features remastered visuals, rearranged music, and new systems like infinite lives. * Classic Version: Preserves the original 2002 gameplay exactly. All text in the Classic version is in Japanese.

The remake holds an Overwhelmingly Positive rating on Steam, reflecting strong reception for the modernization of the series' first Windows title. The Deluxe Edition includes a digital sound player app (or Steam soundtrack) alongside both game versions.

Release History

Embodiment of Scarlet Devil was self-published by Team Shanghai Alice at Comiket 62 on August 11, 2002, with a retail release following on September 22, 2002. As the first Windows-era Touhou game, it marked a "clean slate" for the series after the PC-98 titles, introducing the engine and mechanics that would define the franchise for decades.
