CHAPTER 1
Tower of Samsara
On the day he stopped counting, Kai stood on the Tower's first step once more.
WORLD
Promises made to allies vanish without a trace, and Kai alone remembers every rebirth.
But at some point, a voice that remembers Kai begins to reach him.
The sky-piercing Tower of Samsara. Those who fall here do not die. They simply lose everything and return to the very first step.
On the day he stopped counting, Kai stood before the Tower once again. Allies who greet him as a stranger every time, enemies who wait in the same spot every time. And at the top of the Tower, the Administrator, who watches over every rebirth.
The higher you climb, the more the darkness lifts, as forgotten names and the truth of a vanished kingdom slowly come to light. What awaits at the end of the loop?
CHAPTER 1
On the day he stopped counting, Kai stood on the Tower's first step once more.
CHAPTER 2
The city of the sealed crown. Beneath the collapsed floodgates, the voices of refugees still linger.
CHAPTER 3 Coming Soon
A frozen sea where the signals went silent. Retrace the routes of the ships that never returned.
CHAPTER 4 Coming Soon
A sky road that reconnects the severed floating isles. Beyond the storm, dawn is coming.

FEATURES
We've layered party-building strategy on top of stress-free idle progression.

01 · AUTO GROWTH
Even while you're offline, your party keeps fighting on its own and piling up rewards. Just come back and collect them for stress-free progress. With 2x and 4x speed auto battle, you can enjoy every Ultimate animation in all its glory.

02 · PARTY STRATEGY
Front and back rows, five elements (Fire, Water, Earth, Wind, and Lightning), and roles from tanks to healers and boss-specialist DPS. Who you place where changes the flow of battle.

03 · MYTHIC SUMMON
A Mythic-exclusive prism effect where the card splits open and light bursts out. The pity gauge guarantees a Legendary within 70 summons and a Mythic within 90, taking the pressure off summoning.

04 · REINCARNATION
Even as the climb repeats, your growth and clues carry over to the next journey. Raise your heroes to the max with star promotions, Awakening, and Gear Enhancement.
STRATEGY MODE · SLG
Enjoy Strategy Mode alongside your climb up the Tower. Grow your Estate, lead an Airship fleet, and expand across the sky map with your Clan. In the closed beta, you can start with Estates, the World Map, and Clan Rallies.

01
Construct buildings, train soldiers in the Barracks, and grow your Estate through research.

02
Send Airships across the sky map to gather resources and hunt monsters. Each Airship skin has its own appearance and Ultimate animation.

03
Face tough opponents with your Clan. Start a rally to bring allied fleets together and challenge fortresses and the Storm Whale.

04In Preparation
Compete against other Clans in duels with a different theme each day of the week. League rankings and the Monthly Cup determine the next tier. These will open gradually after the closed beta.

MADE BY ARUMY
A beautiful world, held in both arms
Arumy comes from the Korean word areum. It is the areum in areumdapda, “beautiful,” and in han areum, “an armful”: as much as you can hold in both arms. It is also the name of our very first player, who played this game before anyone else and gave us the most honest feedback.
Our emblem comes from the flower lattice of traditional Korean doors. Four overlapping circles bloom into a flower, the diamond around it holds it close, and the rouge gem at the center is the heart.
