i put down the name of the persona, but i'm a bit confused about the name though being Izanagi, i remember Yousuke saying Adachi's persona's name was Izanami when he summoned it. and i'm pretty sure Adachi called it Izanami as well.
as for the cabbage thing it's cause in the game he was talking about the good deals he would get on buying cabbage at Junes. it wasn't anything central to the story line just a little tidbit he mentioned when you run into him.
