So I downloaded O Ilusionista's Nightwing and patched him for add004. during single mode he is able to operate normally, however when you enter simul mode, no matter whether he is p1 or p3 he won't move at all. the only functions he has available is stance switch and jumping.
i probably wouldn't say a persona like game, since they usually look like actual students in those kinds of games. if anything shun'ei is dressed more like the usual japanese chuni students who so desperately want to stand out that they have convinced themselves they have hidden knowledge or secret powers.
