24hr Challenge
The 24hr Challenge is a game mode unlocked after completing Chapter 5-1 in the Main Story. It featurrs 24 levels which can be reset daily after 5:00 AM (UTC-8).
Each level, a player must select up to three Karma to face off against another player's team. Unlike normal Karma battles, Karma can become damaged during challenges (only valid inside 24hr Challenge and resets when you reset 24hr Challenge) which decrease the Karma's stats, making later challenges more difficult as opponent strength increases while the amount of usable Karma decreases.
Mechanics
There are 24 challenges where the opponents in each challenge are matched based on the player's strongest 6 Karma owned, with later challenges becoming increasingly difficult.
Guardian Effect
Players can select two Lv. 20+ Karma to act as "Guardian" Karmas to further boost the player Company's strength. Since Karma can be damaged during challenges, this is one of the methods to have a form of strength which does not get depleted.
Each week, there are two featured Karma which give additional "Guarding effect". The "Add Now" button can be used to automatically select the Featured Karma for that week.
A featured Karma gives 25% Guarding effect while a non-featured Karma gives 5%. The following table shows the total amount of Guarding effect possible depending on the Karma used:
| Karma 1 | Karma 2 | Total Guarding Effect % |
|---|---|---|
| Non-Featured Karma (5%) | Non-Featured Karma (5%) | 10% |
| Non-Featured Karma (5%) | Featured Karma (25%) | 30% |
| Featured Karma (25%) | Featured Karma (25%) | 50% |
Quick Clear
The Quick Clear feature is enabled after completing Challenge 12 and allows players to skip challenges up to:
- Without VIP: Clear 22 challenges
- With VIP: Clear all 24 challenges
This allows players to go through levels without needing to use or damage the Karma. There are no downsides to Quick Clearing over normally doing the Challenges, so it is always recommended to Quick Clear once it's unlocked. You can't bypass or abuse the Quick Clear by doing some easy challenges first and then Quick Clear, it will just fast forward you to the same Challenge you would've been sent to if you had Quick Cleared from the start.
Quick Clear remembers your highest Score ever, so if you ever made it to Challenge 12 and Quick Clear on the next day to Challenge 4, but choose not to manually progress any further, on the following day you will still Quick Clear to Challenge 4.
Battles
Like normal missions, there will be two key attributes for each challenge, and players will select up to three Karma to battle. Unlike normal missions however, Karma deployed will take damage during the battle which will persist until the player resets.
Company Strength Calculations
A rough calculation that can be used to determine if you are strong enough to defeat the opponent is the total amount of Strength. When first previewing the opponent, the opponent's Company Strength and Karma Strength will be shown.
When selecting Karma, before confirming, the player's own Company Strength will be shown. If the player's Company Strength is greater than the opponent's Company Strength + Karma Strength, then this is a rough estimation that a player can possibly win.
This value is not exact though since during battle calculations, attributes are weighted differently. For example, if two Karma have the same amount of stats (Karma strength), but one has a higher Decision stat value, then during a Decision-based challenge, the Decision-heavy Karma will have a greater amount of Karma strength.
Damage Calculations
Karma will take damage in battle from left-to-right by continuously subtracting from the attribute. Damage is calculated by subtracting the player's Karma from the enemy's attribute stat total until either the enemy's total or the player's Karma in that attribute reaches zero.
Here is a sample calculation:
| Opponent's Karma Decision Stats | |||
|---|---|---|---|
| Karma 1 | Karma 2 | Karma 3 | Total |
| 50 | 100 | 100 | 250 |
| Player's Karma Decision Stats | |||
| Karma 1 | Karma 2 | Karma 3 | Total |
| 100 | 200 | 200 | 500 |
Karma 1
- Player Karma 1 has a Decision stat of 100.
- Subtract 100 from the Enemy's Decision Stat Total and 100 from the Enemy Karma from left-to-right.
- Player Karma 1 used all of its Decision stat and takes damage to its Decision stat.
This is what the stats look like now:
| Opponent's Karma Decision Stats | |||
|---|---|---|---|
| Karma 1 | Karma 2 | Karma 3 | Total |
| 50-50=0 | 100-50=50 | 100 | 250-100=150 |
| Player's Karma Decision Stats | |||
| Karma 1 | Karma 2 | Karma 3 | Total |
| 100-100=0 | 200 | 200 | 500-100=400 |
Karma 2
- Player Karma 2 has a Decision stat of 200.
- Subtract 200 from the Enemy's Decision Stat Total and 200 from the Enemy Karma from left-to-right.
- Since Player Karma 2 has a greater Decision Stat Total then the Enemy's Decision Stat Total, Player Karma 2 only takes partial damage equal to the Enemy's Decision Stat Total left.
This is what the stats look like now:
| Opponent's Karma Decision Stats | |||
|---|---|---|---|
| Karma 1 | Karma 2 | Karma 3 | Total |
| 0 | 50-50=0 | 100-100=0 | 150-150=0 |
| Player's Karma Decision Stats | |||
| Karma 1 | Karma 2 | Karma 3 | Total |
| 0 | 200-150=50 | 200 | 400-150=250 |
This means that Player Karma 1's Decision stat is now 0 for the rest of the 24hr Challenge, Player Karma 2's Decision stat is 50, while Player Karma 3's Decision stat remains undamaged.
Undo
It is possible to undo the result of the battle by using Gem x5 (as many times as you want). This will revert the damage taken by both the player and the opponent.
Resetting
Every day after 5:00 AM (UTC-8), a player can reset the 24hr Challenge. This will reset all damage taken as well as all the Challenges and Karma Deploys (whether they were completed or not). This includes unclaimed rewards, so be sure to claim all rewards before resetting.
Karma Deploy
There are four different genres at the left of the screen that unlock depending on how many 24hr Challenge Missions a player completes.
Tapping on the genre brings up a list of 4 random Karma for a player to select as well as a list of rewards. A player selects the Karma he/she has and then deploys the Karma for two hours. After two hours, a player can claim the listed rewards.
| Genre | # of Missions to Unlock | Rewards |
|---|---|---|
| Sci-Fi | 6 |
|
| Thriller | 12 |
|
| Action | 18 |
|
| Romance | 24 |
|
The 4 random Karma also give two types of bonus: Karma Bonus and Star Bonus.
Karma Bonus depends on the rarity of the Karma.
- R = 25% Bonus
- SR = 50% Bonus
- SSR = 100% Bonus
Star Bonus depends on how many star-ups the Karma has. Each star is +5%.
Resetting the 24hr Challenges also resets these as well, so be sure to complete/claim any incomplete or unclaimed deploy rewards before resetting.

Tips
To easily reach the last node, try to keep all your Karmas in your possession below level 20 and collect as many Star Up items and Experience Items like 
Encounter Wish, 
Bond Wish and 
Confess Wish as you can.
Reset the 24hr Challenge while having only low Karmas, this will set the list of your opponents to the same state as you're currently in. Only afterwards level and star up all the Karmas up at once, so they become unlocked for the battles. This tactic will make everything way easier, as if you do it the other way around, or try to progress through the tree gradually.
- Always weaken the opponent with already damaged Karmas, before taking new ones.
- Sometimes it makes sense to deploy only two Karmas instead of three, for example if you have 2 Karmas which are 90% damaged and one that is only 20% damaged
- Always filter for the required Attribute and select accordingly.
- Try to place one strong Karma in your possession on the 3rd Spot, so the damage to the Karmas on the first two spots will become less.
- Observe the battle instead of skipping it. You can see the attribute bars of the opponent Karmas decreasing with each hit of your own, this way you know which attributes can still hurt you (if they're not completely depleted)
- It also doesn't result in anything attacking the opponent with an attribute, which is already depleted for all of their Karmas to 0. For example, if the bar of the opponent is completely grey for the Creativity round, it won't result in anything attacking your opponent with Karmas which also have only Crativity strength left.
