Why should Juin be a coward? So he doesn't try going anywhere out of sight? They should have used other methods to protect him instead of limiting him so much.
At this point, the only reason I can see for Juin's soul to be shackled is to limit his power and give him the choice on how to live: supernatural or not. It might be for protection, but it just doesn't seem safe. He repeatedly gets attacked and is always in danger physically and spiritually. If the shackles are in place to keep Juin from going on a rampage....maybe? Wouldn't he be more unstable and likely to explode after being so restrained his entire life? It seems like he should've been able to grow into his powers naturally. This could also tie into why he wasn't with Warlock. Did Warlock actually lose Juin or just lose track of him? Neither or these seem too plausible given the power he's demonstrated. Maybe he left Juin in a human situation to distance him from the supernatural thus allowing him to have a "normal" existence.
