Scarlet Girls is a visually engaging Idle RPG that transports players into a futuristic world where powerful, enhanced female warriors—known as mecha waifus—stand as humanity’s last line of defense. Set in the year 119 of the Old Euro Calendar, the world has undergone devastating mutations caused by widespread catastrophes. These events have transformed animals into monstrous creatures that now roam the Earth, pushing mankind to the edge of extinction. In this post-apocalyptic setting, you step into the role of commander, tasked with assembling a powerful squad of these cybernetic heroines to fight back the onslaught of “catastromechs” and restore order to a broken world.
This beginner-friendly guide will walk you through the foundational systems of Scarlet Girls, helping you grasp essential mechanics, understand your squad, and maximize your early-game progression.
Getting Started with Combat and Core Gameplay
At its core, Scarlet Girls offers a laid-back, Idle combat system ideal for players who enjoy strategic planning without the need for micromanagement. Battles unfold in a turn-based structure, where your units and enemy forces take actions according to their Speed stat. Each cycle completes once every unit on the field has taken their respective turn. You can field up to five characters in combat, and with features like “Quick Dispatch,” the game can automatically select your strongest lineup to get you into battle quickly and efficiently.
Each character—referred to in-game as Stellaris—comes equipped with powerful active and passive abilities. These abilities are activated automatically during battles and typically include cooldowns that determine how frequently they can be used. The overall flow of combat emphasizes preparation over action, so your effectiveness largely depends on how well you assemble and synergize your team ahead of time. Once battle begins, you’re essentially a spectator, watching your strategy unfold.
To make battles even more streamlined, the game includes quality-of-life features like adjustable battle speeds (up to 3x) and the ability to skip scenes altogether. While there are a variety of modes in the game, beginners are best served by focusing on the main campaign—Exploration Mode. This story-driven PvE journey takes players across multiple chapters, each filled with stages leading to powerful bosses. Completing stages not only advances the story but also earns valuable in-game rewards like currency, gear, and upgrade materials.
Idle Rewards – Earning While Away
One of the core benefits of Scarlet Girls being an Idle game is its generous AFK (Away From Keyboard) reward system. Even when you’re not actively playing, your team continues to fight and earn resources for you. These rewards accumulate for up to 12 hours and can be collected at any time from the Exploration interface. The amount and quality of AFK rewards depend heavily on how far you’ve progressed in the campaign, so advancing through stages will boost your offline earnings over time.
Meet the Stellaris – Your Combat Specialists
Your team’s effectiveness depends entirely on the Stellaris you recruit. These characters are obtained through a gacha-style summoning system known as Echo. Every Stellaris has a unique combination of skills and elemental affinities, giving the game a strong strategic layer. Elements interact in a rock-paper-scissors format that rewards smart team composition:
- Void beats Inferno, but is weak to Phantasm
- Inferno overpowers Rancor, but falls to Void
- Rancor has the edge over Phantasm, but loses to Inferno
- Phantasm triumphs over Void, but is vulnerable to Rancor
- Nebula is neutral, offering flexibility in team builds
Each Stellaris is also categorized into one of four classes, which define their role in your squad:
- Paladins act as frontline defenders with high durability, designed to soak up damage and shield allies.
- Support Stellaris provide healing, buffs, and other utility, usually positioned safely in the backline.
- Devastators unleash powerful energy-based attacks, delivering significant AoE damage or focused nukes.
- Assaulters excel at physical damage and quick eliminations, ideal for targeting priority threats.
Summoning via the Echo System
New Stellaris are acquired through the Echo summoning feature, which is essentially the game’s gacha mechanic. Characters come in four rarities—R, SR, SSR, and the highly coveted SSR+. Naturally, higher rarity characters boast stronger stats and more impactful abilities. While luck is involved, Scarlet Girls has a pity system in place that guarantees an SSR character every 40 summons.
Currently, the game features one primary summoning banner—Normal Echo. Players use Echo Tickets or Diamonds to perform summons. Each summon grants Echo Points, which can be accumulated and eventually traded in for specific SSR characters tied to their elemental categories (excluding the neutral Nebula). Here’s a look at the probability breakdown for summoning each rarity:
- R Stellaris: Approximately 19.98% chance per summon
- SR Stellaris: Around 2.67% chance
- SSR Stellaris: Roughly 0.13%
- SSR+ Stellaris: A rare 0.01% chance
Given the odds, it’s wise to save and use Echo Points strategically, particularly if you’re targeting specific team compositions.
Final Thoughts
Scarlet Girls offers a rich blend of idle convenience and strategic depth, wrapped in a sleek and stylish package of 2D mecha-themed heroines. As you progress through the game, your focus should be on building a balanced team of Stellaris, mastering elemental interactions, and pushing through campaign chapters to unlock better rewards. With automated combat, offline resource generation, and a vibrant cast of characters, it’s a great entry point into the world of Idle RPGs. Whether you’re a casual player or a hardcore collector, there’s plenty here to keep you engaged while you work toward assembling the ultimate team of cybernetic champions.
