From the very beginning, this project was born out of a dream to create fast, fluid, and visually striking action gameplay, and I’m incredibly excited that you can now experience the full adventure – or get a taste of it with the demo.
Blades flash like lightning. Movements blur like wind. This is the heart of Lost Soul Aside and today marks just the start of your journey.

Demo beginner’s guide: The art of high-speed combat
In this demo trailer, Kaser and Arena join forces to overwhelm enemies with their lightning-fast, high-octane combat style. The trailer showcases radically distinct weapon techniques, split-second combat performances, and breathtaking dance of clashing blades, embodying the game’s combat philosophy – “Strikes roar like thunder, evade fade as phantoms.”
This playable demo features an early-game boss challenge and a mid-game adventure stage, allowing players to experience Lost Soul Aside’s signature combat system:
Core combat: fast-paced, seamlessly smooth, and endless-combos.
- Seamless weapon switching: Sword (split-second strikes) and Greatsword (earth-shattering power) enable endless combo variations, making battles flow like poetry in motion.
- Aerial combat: Launch enemies mid-air and strike with unstoppable combo storm.
- Boss encounters: Face off against enemies like Rose Queen, Holy Knight Commander Victor, and the titanic Ancient Mecha. Master movement, timing, and counterattacks to survive.
Combat tips: Precise Dodges, Precise Blocks, Energy Burst Pursuits
- Perfect Dodge: Evade at the last moment to trigger a special counterattack.
- Precise Block: When blocking an enemy’s powerful attack right as the blue circle warning appears, you’ll stagger them and create an opening.
- Burst Pursuit: When a blue glow appears on Kaser, press the Burst Pursuit button to unleash a spectacular strike.
