To start, I finished the event's story mode, in the morning I'm 100% screwed: do 100 Shots missions, that I developed a strategy for myself.
Now I'm on Shot 21, because I'm doing 30 Shot Quests per day: 10 Quests in the morning, afternoon and evening, for me to take a break or do Bleached Earth's Free Quest to focus on the BB Summer, Jalter Summer and Medusa Bonds.
Speaking of Bonds, BB has just reached Bond level 7.
And I took the opportunity to spend the Evocation Leaft, to obtain the Hokusai Saber.
Now I have 2 versions of Hokusai: Foreigner and Saber.
Apparently I didn't need to spend Apples, at least I'll save them for the summer event next month.
UPDATE
Medusa has just reached Bond level 7.
