Training First-Time Clear Rewards

You can also earn Dimensional Crystals by clearing each difficulty in Training for the first time. Higher difficulty levels unlock as your Special Ops Rank increases.
Fierce Battle Arena Rewards

You can also get Dimensional Crystals from the ★ completion rewards in the high-difficulty content "Fierce Battle Arena" which is unlocked at Special Ops Rank 2.
Free Dimensional Crystals from Web Store

You can receive 150 free Dimensional Crystals from the Web Store. There are no special conditions; simply log in and claim them.
Special Request Rewards

Achievement Rewards

You can get Dimensional Crystals by completing achievements.
Message Rewards

You can earn Dimensional Crystals by reading messages. It only requires reading some dialogue, so consider it an additional way to obtain them.

In Kaiju No. 8, the recommended use for Dimensional Crystals is the Gacha. Gacha Tickets are limited to sources like Guide Missions and event rewards, so you'll primarily use Dimensional Crystals for pulls.
Quick Claim for Expedition

You can also recover Stamina by using Quick Claim for Expedition Rewards. This can be done up to five times a day, and the recovery efficiency is higher than spending Dimensional Crystals directly, even up to four uses, so prioritize consuming those first.
Stamina for Dimensional Crystals
Times | Dimensional Crystals Required |
1st-2nd time | 20 |
3rd-4th time | 30 |
5th time | 50 |
Using for Stamina Recovery
Using Dimensional Crystals to recover Stamina also grants Reinforce materials and increases your Player Rank.
Level Up Battle Pass

You can also use Dimensional Crystals to level up the Defense Force Pass. This is generally not recommended, unless you absolutely won't be able to get the featured reward in time.
