In a highly advanced future city, a special energy source known as Elemental Energy Crystals has been discovered.
These crystals can only release their power stably when arranged in specific patterns — the classic shapes of Tetris blocks.

You possess the rare Attunement Ability, allowing you to manipulate these energy crystals.
Rotate, drop, and clear lines… every precise combination becomes the combat power of the girls.

Maiden  Legion is a deep fusion of falling-block puzzle and tower defense.
You’re not just playing a mini-game — you’re actively assembling battle energy on the battlefield and summoning the members of the Girl Legion to fight alongside you.

But a carefully laid trap leads to the capture of seven of your companions.
Only Rena, Greta, and Sylph remain by your side.
To rescue the controlled girls, you must infiltrate seven enemy-occupied districts of the city, destroy their strongholds one by one, and disable the control devices.

Each girl you free unlocks her unique crystal color.
When all ten members are finally reunited, the Girl Legion will continue protecting the city.

Game Features:

• Tetris-style gameplay that directly drives combat — clearing blocks summons and empowers the girls

• Ten distinctive members of the Girl Legion, each with her own color and combat role

• Story and stages set in a cyberpunk future city

• Full experience from the rescue operation to endless city defense missions

• Adult content and character interactions (including nudity and sexual scenes)

The moment the blocks fall is both a strategic choice and the beginning of fighting side by side with the girls.
Join the Maiden Legion and bring them all back.
