Rows kept from run to run have one purchase counter in the data, so their limits most likely count across all runs: the boss card can be bought once per account (inferred). Rows added anew each run start a fresh limit.

Dialogue

Show every line

First visit (CLASS B open)
A world without smiles and humor has no
bright future. Let's see if you're worthy of it.
CLASS A unlocked
I see that you're not useless,
but I'm not saying you're worthy.
CLASS S unlocked
With no symbol, can you become a
bright, shining light? Let's see it.
CLASS SS unlocked
This will tell me if you can
be a light for the people.
CLASS SS cleared
So you wished for one future alone.
Perhaps it can be changed.

Lines on the Climax Battle screen as you progress (when each one shows is read from the data: inferred).

How Climax Battles work

Unlocked by clearing Main Quest 5-9 (Normal).
CLASS B → A → S → SS: clearing a class unlocks the next.
No Stamina, no skip tickets, no turn limit, no team restrictions.
A boss changes phase at set HP thresholds; until the phase change plays, its HP cannot drop below the threshold.
Each class pays Hero Gems ×50 on its first clear of every run (inferred: the data keeps this reward per run); CLASS SS also gives the boss's UR card on the account's first clear ever.
Climax Emblems drop from every clear and carry over to the boss's next run.
Tries instead of Stamina: 3 a day*, shared by every Climax Battle, reset at 00:00 (JST). A defeat or a forfeit costs no try.
*Inferred: the number is server-side; no run's missions ask for more than 3 clears a day, and many ask for exactly that.

The game's own help

What are Climax Battles?

Climax Battles are extreme difficulty challenges with the ultimate bosses.
Complete the highest difficulty level CLASS SS to get your hands on a new UR character.

You will receive Climax Emblems as a part of your completion rewards.
Use these Climax Emblems to purchase various items at the Climax Battle Event Gear Shop.

Climax Battles are not always open.
Once an event period closes, you will only be able to receive Mission Rewards and use Climax Emblems to purchase items.
After some time, you will no longer be able to access Climax Battles to receive rewards or use your Climax Emblems. Climax Battles will be closed until the next event period.

▼How to Unlock Climax Battles
Complete Main Quest Ch. 5-9 (NORMAL)

Classes

There are several tiers of difficulties in Climax Battles labeled with a different "CLASS".
The next CLASS becomes unlocked when you complete the previous CLASS.
The higher the CLASS, the more difficult your opponents will be.
In exchange, your rewards will get better as you climb up in difficulty.

The most difficult CLASS SS is quite the challenge, but you will receive a UR character the first time you complete it.

Tries

Instead of using Stamina, you will have a number of "tries" to use when taking on Climax Battles.

There is a limit to the number of tries that you can use. They reset at 00:00 (JST) every day.
You will not use up your tries if you are defeated or if you forfeit.
*The daily number of tries is for all Climax Battles.

Event Gear Shop

You can use the Climax Emblems you obtain to exchange with various rewards at the Climax Battle Event Gear Shop.

At the Event Gear Shop, you can exchange your Emblems with the UR characters that appear in battle as bosses, UR character pieces, UR character orbs, and more.

Even after one event period ends, Climax Emblems can be exchanged later in the next event period where that boss appears in battle.
However, Climax Emblems will not roll over if the boss that appears in battle is different.

Missions

You can obtain lots of different rewards by completing the various tasks given in the Climax Battle Missions.
You can check on the progress of your Missions by going to the Missions tab within Climax Battle.
*Climax Battle Missions will not be included in the main Missions area from the Home Screen.

There are two types of Missions—"Daily" and "Ongoing".

Tap on the "Claim" button after completing a Mission to receive your rewards.
Tap on "Claim All" to receive all of the rewards of Missions that you have completed.

Tap on "Filter" to see Missions based on their completion status.

Phases

During Climax Battles, a new Phase begins every time certain set conditions are met. This causes changes in attack patterns and sometimes triggers different animations.

When an animation is triggered because of a Phase change, HP will not go below a certain amount, and the opponent will not take any damage.

Data: the game's final master data (client 5.0.0). It holds one copy of each boss's battles, so early runs may have used other enemy stats or rewards.
