Akaneanon here. Reporting.
I completed the third challenge with the help of Shiroko Terror, my beloved Akane, School Neru, Tsubaki, Ako and Rio. Man, School Neru was a beast, she was going toe to toe with Wolfseggs Terror, that evil pancake never stood a chance, with the help of Rio, I copy Neru's skill, attack again and boom, third challenge completed + the time record.
