I can kinda see that.P3 is one of those games where you will more than likely hate one of the cast.
For some, it's Yukari, some Ken, others Fuuka.
For me, it's Akihiko after I mellowed on Aigis.
Personally the P3 cast is my favourite and I like all of them/love most of them. Ken is probably my least favourite in the group, but I still really like what they did with his character.
