How to Progress the Story
Read Through the Episodes
The story is basically composed of stages that only contain episodes. Advance the story by reading through the episodes.
Some Stages Have Battles
Battles occur at certain points in the story. Since you can use your save data in these battles, battle them with your trained Combatants.
Chaos Appears Mid-Chapter
You will face one Chaos battle per chapter. Defeating a new story Chaos unlocks it for replay in Chaos Manifestation.
Clear Promotion Missions to Unlock the Next Chapter
To progress the main story in CZN, you must clear Promotion Missions. These missions become available after completing all combat missions in a chapter.
Captain Level Is Also Required
Promotion Missions also require a specific Captain Level. If your level is too low, raise it by completing Simulations and Growth Guide missions.
What to Do If You're Stuck
Create Save Data in Chaos
If you're struggling with story battles, we recommend creating more powerful save data in Chaos. Repeatedly challenge it to acquire powerful equipment and Epiphanies.
Train Your Combatants
Before tackling story or Promotion Missions, ensure you raise your Combatants' Level and Potential as much as possible. If you can still improve them, continue training and then attempt the mission again.
