This is a new fusion feature that allows for multiple copies of identical units (base rarity 1★ - 4★) to be fused in bulk.

You can access Bulk Fusion by accessing the Units menu and tapping on Bulk Fusion.

- Units used as fusion materials will disappear.
- Certain conditions/filters can be set to customize a bulk fusion, such as applicable unit base rarity (1★ - 4★), restricting fusion to Lvl. 1 units only, or limiting fusion to units in Reserves.
- Trust Master Rewards will be obtained and automatically sent to your inventory for units whose Trust Mastery reaches 100%.
- If a unit reaches 100% Trust Mastery in the middle of a bulk fusion with identical copies of the unit still remaining, no further units will be fused to it.
