Minato is someone from the same world as Rise, but she never knew him until he arrived in Death City. He had been here for a short while at the very beginning but was returned by BREW before she got to know anything other than him being from Port Island. Needless to say she was glad when he returned and she was able to get to know him.

She learned that he also had the ability to summon Persona, and numerous ones just like Souji. He had a group of friends who also had designated Personas. Like the Investigation Team they fought Shadows, but their story is a very different one.

Strange similarities aside, Rise likes Minato because of his languid manner and sense of humor. He's someone very easy to relax.
