Super Trust Master Rewards are rewards from units that have been awakened to 7★. They can be obtained by increasing their Super Trust Master percentage to 100%.

You can fuse units that are identical to your 7★ base unit to increase its Super Trust Master percentage.

The percentage value that can be obtained from units used as fusion materials varies according to the unit's rarity.

Percentage value gained by rarity:
・When fusing a ★5: +50%
・When fusing a ★6: +50%
・When fusing a ★7: +100%

• *Fusing an identical 7★ unit to your base 7★ unit will raise its Super Trust Master percentage by 100%.
• *Fusing identical units to your base 7★ unit will increase its Super Trust Master percentage regardless of whether or not you've obtained that unit's Trust Master Reward.

You can obtain special bonuses when you fuse an identical unit to a particular 7★ base unit for the very first time.

• *Bonus rewards for any particular 7★ base unit can only be obtained once.
• *Even if multiple identical units are fused to the same 7★ base unit, its bonus rewards can only be obtained once.
• *Whenever bonus rewards qualify as obtainable, you will be notified after the fusion results screen. Bonus rewards can then be claimed from your mailbox.
