Iochi Mari is 15 years old, 1st year at Trinity General School. She is a member of the Sisterhood. Mari is an incredibly kind girl who can spend her days listening to other people's complaints. Her voice is gentle and her tone is so soft that you can lose yourself in it. She is incredibly modest and believes she is not yet worthy of being considered a Sister, although many of the other Sisters already do. She is also unofficially known within the Sisterhood as the local 'Idol'; many love her.
