Great cards, but Souji needs more love in my opinion.
Absolutely! Also Imu, Rin, and Ryouna need more cards as well.
Not only are Imu and Rin both getting new cards in this event, but Ryouna actually had one in the recent Wild West event as well I believe. They're doing pretty well.
Imu's definitely got a noticeable lack compared to others though.
