Hello, Yongcheon Girls’ High School students. Christmas is already just around the corner.

It seems that even Yongcheon Girls’ High School, sunk deep in the abyss, is busy preparing for the holiday season.

This v0.4.0 update introduces a large amount of Christmas-themed content, along with various system improvements and balance adjustments.

Let’s take a look together!

🎄 1. Christmas Edition

Even Yongcheon Girls’ High School, filled with spirits, welcomes Christmas.

The students and monsters alike seem to have gone all-in on their Christmas outfits.

In this update, festive elements have been added throughout the game,

from the title screen to in-game visuals.

  • Snowfall effects drifting through the fog

  • Christmas costumes applied to monsters

  • Santa hats for Haneul and Sumi

This Christmas edition will remain available until January next year,

so enjoy meeting monsters in a variety of festive costumes.

🎯 2. Projectile System Enhancement

The long-awaited projectile system upgrade,

which had been delayed due to ongoing development, is finally complete.

Previously, projectiles bouncing through the fog felt somewhat plain and rigid.

With this update, projectile visuals have been significantly improved,

reflecting each character’s signature colors and weapon characteristics.

  • Clear visual expression of each character’s unique weapon

  • Fog flash and camera shake effects added when projectiles ricochet

  • More dynamic and visually satisfying projectile action

We hope you’ll now enjoy not only strategic deck-building,

but also the tactile feel and visual impact of each shot.

🎬 3. Act Ending Cutscenes Added

Based on feedback that transitioning immediately to the next area after clearing an Act felt abrupt,

ending cutscenes have been added for each Act.

  • Character-specific ending cutscenes after defeating bosses

  • Smoother narrative flow into the next Act

  • Some elements are still in progress and will be refined later

This update includes ending cutscenes for Act 1 and Act 2.

🧿 4. Relic Reward Skip Option Added

Previously, all relics had to be obtained,

which could feel restrictive when dealing with relics that had drawbacks.

With this patch, a “Skip” option has been added

to all relic reward sections, allowing players to make more strategic choices.

❄️ Winter Sale Notice

Alongside the v0.4.0 update, the Winter Sale has begun.

Enjoy 20% off, and we appreciate your continued interest and support!
