I'm about to tag into a post so I thought I'd drop a comment here. Sui has one red lock and one black lock. The red lock comes from hiding the fact he's actually a nine-tailed fox temporarily reincarnated as a human. The black lock is the result of hidden memories. I'm fine with the red lock being opened fairly quickly, but for now, I'd like to keep the black lock.

Let me know if you have any questions.
