How to Raise Character Levels

You can raise a character's level via the Enhance screen by using Defense Force Manuals. Leveling up boosts their Stats.
1. Tap "Enhance" on the Character Screen

Tap the "Enhance" button located at the bottom right of the character details screen.
2. Select Defense Force Manuals to Enhance

Select the materials by tapping the Defense Force Manuals or simply tap "Auto-Select," then press "Enhance" to complete the process.
Unlock the Level Limit

Characters have a level cap, but you can raise this limit by performing a Level Limit Unlock. Furthermore, when you perform a Level Limit Unlock, their Stats will increase, and new Passive Skills will be unlocked when breaking the level cap at Lv. 40, Lv. 60, and Lv. 80.
How to Unlock the Level Limit

On the character enhancement screen, once a character has reached their current max level, tap "Limit Unlock" to consume materials and unlock the new cap.
Spec-Ops Rank Required at Set Levels
To unlock specific level caps, a certain Spec-Ops Rank is required. If you cannot perform a Level Limit Break, try raising your Player Rank and attempting the Promotion Exam.

How to Get Defense Force Manuals
Get from Training

Defense Force Manuals, the main level-up material, can be obtained from the "Defense Force Manual" Training. Since rewards increase with difficulty, farm the highest difficulty you can clear.
Other Ways to Obtain Defense Force Manuals
Defense Force Manuals can also be obtained from the Shop by exchanging Encounter Stones, Emblems of Defense, or Credits, as well as from the Defense Force Pass. Additionally, they may be available through Story quests, the Beginner's Guide, event rewards, and more.
