Put Ivy in ZM4 Onslaught Shop as a permanent character

Unlike other ZM playable boss characters, Ivy does not have a permanent variant. She's only obtainable in Arcadia's pass. And after you reach the final level, it's no longer possible to obtain her as a temporary character. There is no pieces to permanently unlock her either. In my opinion. I suggest Ivy to be added to ZM4 Onslaught Shop. If there is no space, Ivy can be replaced with Ivy Doll Red Piece. I hope you let people enjoy playing as Ivy whenever they want.
