>>58621382Even without worrying about the opening, LGPE just doesn't fit into any timeline because of Mina's appearance, wherein concept art puts her around 13-15 years old.
Problem is, if you believe LGPE to be compatible, then that'd make Mina 33-35 by the time of SMUSUM, which is 20 years after the events of Kanto. Which means she shouldn't be a Trial Captain, as they have to resign from their position at age 20.
