Seater Port in Chroma QuarterNion
I realize this question is from years ago, but it can be a confusing part of Chroma Quaternion, so I'll post the answer.
If you're ever unsure about what to do next in (almost) any Exe-Create game, check the "Story" option in the menu. The latest Main Quest entry should suggest what to do or where to go. In this case, it should tell you to go back to Cocoon Forest to look for a new role that will help you sneak into the building that you currently can't enter.
Cocoon Forest is a much simpler maze than it looks. Check any route that leads north, south, east, or west and is not on the flower-marked "correct" path, and you should eventually find all of the area's treasure chests, a boss fight, and the role crystal needed to progress the story.
