I don't even have enough units to fill out a Whaleship yet.
I did the story missions a lot when the 33% off stamina was going and leveled to ~55 in a week to get my max stamina up so I am low on units from the reissued events.
I have 3 5* (Gerberda, Glory of the Sun, and Chocolate Cosmos (Swimsuit)) and 3 3* (Blue Lotus, Mountain Hydrangea, and Gladiolus) HP Absorb units so I might be able to do the "Take Back the Stolen Lifeforce!" Unique mission.
The only thing I need to bloom Gerberda is a second Red Blooming Bird.
I did the first stage of "Skill Clean Sweep Operation" and got the Red Bird I needed from the Quest and Bloomed Gerberda.
I need to level another to 70 before I can bloom another unit.
