Umichi would rather not engage with an orange player and probably suggest to the team not to either. Something along the lines of, "If we are staying on the front lines, we want to be trusted by the other groups on the front lines. Actively engaging and have connections to orange players might cause them to distrust us."
And it would make sense really.
Although I'd rather not have my second character engage with them either, but will if it becomes necessary for your character to have some interaction.

The bin is for a collection of our characters, and so that we can quickly check what the character's level and stats are and such.
And so that people don't do silly things like liferusher did, leveling from 6 to 8, before (probably by accident).
