Card Battle Tips & Current Version

■ Card Battle Tips

(1) Basic Rules

Battles are fought using cards — each card represents an Art.

The party requires Actions to use Arts each turn! (5 Actions are given per turn)

Characters need AP points to use Arts.

(All characters recover 1 AP at the start of each turn!)

Make the most of your actions and AP each turn to defeat the enemy!

(2) Aim for Breakdowns!

The fastest way to defeat enemies is by inflicting Breakdown!

Reduce their Break Count to trigger Breakdown, stopping them from acting and increasing the damage they take.

If you inflict Breakdown on all enemies, your damage will skyrocket!

(3) How to inflict Breakdown?

Use Strike Arts (Red attack cards) to execute Art Impacts and deal Break damage! (Land your attack in the red zone to trigger an Art Impact!)

Each time you trigger an Art Impact, the enemy's Break Count decreases. When their Break Count reaches 0, they will enter Breakdown.

That's when you go for the kill!

(4) Let's get Superior Arts in the Chain!

The higher your Art's Chain Rate (%) is, the greater your chance to trigger a Chain and obtain a Superior Art!

Superior Arts consume more AP, but they're also more powerful! Manage your AP wisely and try them out!

(5) Protect your allies with AC (Armor Class)!

AC (Armor Class) plays a crucial role in reducing damage from enemy attacks!

The more AP you have at the start of your turn, the more AC you'll recover.

Some Support Arts (blue auxiliary cards) can also boost your team's AC. Keep this in mind and stay ready for enemy attacks!

(6) Spirit Arts can be a trump card!

When selecting an Art, you can access character-specific Spirit Arts by choosing the yellow (X) Spirit Card!

Spirit Arts can only be used once per battle, but they're powerful enough to turn the tide!

Use them when the time is right!

(7) Adapt your tactics to the battlefield!

You can choose to break all enemies, focus on a single target, boost your team's AC to withstand attacks, and more! There is no one-size-fits-all strategy!

Flexibility and resourcefulness are the keys to victory!

About the Demo

Spend your school life with beautiful, unforgettable heroines!

Hart Grancer, a former mercenary turned agent of the Ancient Prehistoric Civilization Central Intelligence Executive Agency (A.C.E.), has infiltrated the Academy, a school run by the very agency he serves.

But what seemed like a simple assignment at first — coaching a group of girls, each with their own mysterious reason for being there, and handling miscellaneous tasks from the A.C.E. — quickly turns into something far more dangerous than anticipated, as Hart is tasked with recovering a Grimforge — an ancient artifact at the heart of a massive conspiracy.

Birthday: October 12. Height: 156 cm (5'1"). Weapon: Darts and rapier. Hometown: District 7, Moomoo.

Cheerful by nature and a lover of all things pretty, Akina is a perfectly ordinary girl. Despite her hard work, she can't help but feel overshadowed as she is often surrounded by people with extraordinary talents. There's nothing particularly remarkable about her — except for her surprisingly large breasts.

Birthday: August 15. Height: 156 cm (5'1"). Weapon: Gun and sword. Hometown: Imperial City of Invoa.

The third daughter of a former noble family — as her constant, unprompted quoting of her family mottoes often reminds everyone — Elise is the very picture of haughtiness and pride. Yet despite her airs of superiority, she doesn't handle pressure or criticism well, and a little flattery is often all it takes to wrap her around your finger. Contrary to what one might expect from a well-bred lady, she has a soft spot for all things flashy and sparkling.

Birthday: February 4. Height: 141 cm (4'7"). Weapon: Yoyo. Hometown: District 212, Tajine.

Lively and full of energy, Ling has a small frame and a playful, childlike personality. However, she's actually the oldest member of the group and naturally slips into the role of a caring big sister. Headpats are her weakness, and her quirk is slapping stickers on people, marking them as approved.

Birthday: March 3. Height: 151 cm (4'11"). Weapon: None. Hometown: District 351, Caldoverde.

Shy and quiet by nature, Alesha is more likely to be found tucked away in a corner with a book than engaging in small talk with coworkers or friends. Her reserved temperament shows through in her difficulty with social interactions, and she's utterly hopeless in crowded settings.
Although she's the type who looks slim in clothes, Alesha is actually quite well-endowed.

Birthday: May 3. Height: 141 cm (4'7"). Weapon: Railgun blade. Birthplace: Unknown.

Often seemingly lost in her own world and hard to read, Selene is actually full of passion and a little clingy beneath the surface. Animals are naturally drawn to her, and she cherishes them just as much. Petite in build, she's surprisingly fit and toned.

Birthday: January 18. Height: 158 cm (5'2"). Weapon: Stun rods and heavy pistols. Hometown: District 81, Yamato.

The honor student heroine. Gifted with brains and beauty, her academic prowess and perfect figure have earned her the admiration of her classmates — both men and women. Although serious on the outside, Saki indulges in small pleasures, like secretly writing romance light novels, a hobby she hasn't shared with anyone.

Fragments scattered across the world stand as silent witnesses to the pain of a forgotten age.
Each time our heroines reach for them, they find themselves caught between what once was and what is yet to come.
Within the flow of their ordinary days, desires take root, compelling them to make their choices that will shape their fate.
Thus begins our story, shaped equally from their sins and their prayers.

Hart Grancer, a former mercenary turned agent of the Ancient Prehistoric Civilization Central Intelligence Executive Agency (A.C.E.), has infiltrated the Academy, a school run by the very agency he serves.

But what seemed like a simple assignment at first — coaching a group of girls, each with their own mysterious reason for being there, and handling miscellaneous tasks from the A.C.E. — quickly turns into something far more dangerous than anticipated, as Hart is tasked with recovering a Grimforge — an ancient artifact at the heart of a massive conspiracy.

Amid the rush of their busy days, brief moments of calm appear. In these quiet moments, subtle gestures and fleeting smiles come to light. It is here that the distance between you and the heroines narrows — a small promise of a future yet to be written.

Play the cards that reflect the heroines' personalities and skills, and claim victory in every battle!

Your actions in battle add new cards to your hand.
Will you play your best move now, or save it for the battles ahead?
Every fight is a chance to build your deck!

Equip your characters with artifacts to compensate for their weaknesses or enhance their strengths — the choice is entirely in your hands!
Make your favorite heroine as powerful as possible!

You can also synthesize artifacts to create new ones that inherit the abilities you want!
