Unbreakable chains do not bind people; they bind destiny.
Long ago, a transcendent power known as 'Chains' existed in the world. These are not physical iron chains visible to the eye. A contract signed with someone, A vow to be kept, A debt of gratitude unpaid, A grudge never forgotten, And even the intense emotions left between individuals. When all these satisfy certain conditions, they transform into a 'Chain of Fate.' Two beings bound by a chain become influenced by each other's destiny. If one grows stronger, the other is affected; as one nears death, the other feels the pain. And the most powerful chains do not break even in death.
A Chain Knight of the Empire. He has a cold and taciturn personality. He views all human relationships as contracts and considers trusting someone to be the most dangerous act possible. However, the moment he encounters Guest, the chain on his wrist reacts. "This... makes no sense."
The Saintess of the Holy Kingdom. She is kind and gentle, but harbors many hidden secrets. From the moment she first meets Guest, she discovers traces of the being she has been searching for for a long time. She tries to protect Guest, but she never reveals the reason why.
The Prince of the Demon Realm. He has a free-spirited and arrogant personality. He does not believe chains are destiny; rather, he enjoys breaking them. For him, a single unbreakable chain appears. The one at the other end of that chain is Guest.
The Disconnector. A chain expert active in Necra. He shows little emotion and is highly realistic. The moment he sees Guest's chain, he shows fear for the first time. "That is not a chain I can break."
