Dive into the thrilling world of Scarlet Girls, a brand-new Idle RPG that introduces an all-female squad of technologically enhanced mecha waifus. Set in the 119th year of the Old Euro Calendar, the game unfolds in a post-apocalyptic world where mutated animals and powerful beings have pushed humanity to the brink of extinction. As one of the last hopes for survival, you'll recruit and train these mecha girls to combat the menacing catastromechs and restore peace to Earth. This beginner's guide will illuminate the core game mechanics and various game modes designed to enhance your account's power and progression. Let's get started!
Understanding the Combat Mechanics of Scarlet Girls
The heart of Scarlet Girls lies in its Idle-based combat system, perfect for players seeking a more relaxed gaming experience. Battles unfold in a turn-based format, where the sequence of actions is determined by each character's Speed stat. A round concludes once all allies and enemies have taken their turns. You can deploy up to five characters in battle, and the game offers a convenient Quick Dispatch feature that automatically arranges your team based on the strongest characters available. Once your squad is set, sit back and enjoy the visually stunning animations that accompany each character's unique abilities.
In Scarlet Girls, your characters, known as "Stellaris," possess both active and passive abilities that they deploy automatically during combat. Each skill has a cooldown period, measured in turns, before it can be used again. Crafting a synergistic squad of mecha girls is key to overcoming your foes. The battles occur in real-time, leaving no room for manual intervention; your strategy hinges on the strength of your characters and the strategic line-ups you create to maximize their potential.

Each Stellaris is categorized into one of four classes, each with distinct roles and utilities:
- Paladins – Boast the highest armor stats, acting as frontline defenders to absorb enemy attacks and protect their teammates.
- Support – Equipped with healing and supportive abilities, these Stellaris provide crucial utility from the backline.
- Devastator – Masters of heavy firepower, these Stellaris are designed to unleash devastating energy damage on enemies.
- Assaulter – Skilled in close combat with bladed weapons, these Stellaris excel at dealing physical damage to dismantle and defeat their targets.
Echo – The Gacha System of Scarlet Girls
Recruiting Stellaris is facilitated through the game's gacha system, known as Echo. Stellaris come in various rarities: R, SR, SSR, and SSR+, with higher rarities boasting superior base stats and more potent abilities. At the global launch, the "Normal Echo" banner is available, offering R to SSR Stellaris. You can summon using Echo tickets or Diamonds, with a guaranteed SSR character within 40 summons. Each summon also earns you 20 echo points, and accumulating 2000 points allows you to select a random SSR character from one of four elemental banners (excluding Nebula). The recruitment probabilities are as follows:
- R Stellaris – 19.979% chance per character
- SR Stellaris – 2.667% chance per character
- SSR Stellaris – 0.133% chance per character
- SSR+ Stellaris – 0.010% chance per character
