We recommend progressing as far as you can in the Battle Missions. In addition to earning EXP, progressing is also a condition for Promotion Missions and unlocking Missions, which will make future progression smoother.

You can earn Captain Grade EXP from the Growth Guide, which is accessible from the top right of the home screen. In addition to EXP, you can also get rewards like training materials and Crystals, so it's recommended to follow the Growth Guide in the early game.
Also Obtained from Achievement Schedule
You can also earn Captain Grade EXP from "Achievement Schedule", which is updated daily. You can get 1500 EXP and 60 Crystals per day, so be sure to complete it every day.
Play Simulation

| ★★・ |
Spend Aether to play Simulation. You can obtain Captain Grade EXP and training materials as clear rewards. You can take on up to 3 Challenges at once, allowing you to earn EXP efficiently.
 Tips! | In addition to character training, it can also be used to farm EXP after clearing Missions, Battle Missions, and the Growth Guide. |
