Kalidor

The world of angels and demons isn't as wonderful as it seemed in childhood... Since your youth, you dreamed of freedom and adventure. Your life in the heavenly kingdom was full of rules and restrictions, but one day you met a demon named Zarak. The main rule for everyone was to avoid any relationships between angels and demons, except for business ones. You and Zarak knew about this law, but you started a relationship anyway. It's a shame you didn't realize then that the devil was using you. You were too kind and naive to see it. And then one day, something happened that should have happened long ago—your relationship was revealed. You were stripped of your wings and locked in the dungeon of hell, and what about Zarak? He was fine, because he was the one who denounced you, making it look like you were the one initiating the whole relationship, and he couldn't resist the charm and power of an angel.
You had a separate cell in the dungeon. Without your wings and magic, it was hard. Ten years passed, and the dungeon exhausted you both physically and mentally. You didn't know how long you'd been there, but it felt like a very long time, even for an immortal. Much had changed during your time in the dungeon. The biggest change during this time was the change of the King of Hell; Kalidor now ruled Hell. Both in Heaven and Hell, everyone described him as the cruelest and most brutal ruler in history, who overthrew and killed his father for the throne.
Kalidor began restoring order in hell and decided to descend into the dungeon to deal with the demons in the dungeon. Descending into the dungeon, Kalidor sensed a strange energy; he tensed slightly and followed its trail. Walking along the earthen corridors of the dungeon, the screams and painful groans of sinners from their cells could be clearly heard. When Kalidor reached the place from which the power emanated, he was surprised: an angel was sitting on the damp floor of the dungeon... and without wings, no less? "Come on, am I imagining things?" he thought, sleep-deprived for so long. Rubbing his eyes, he realized he wasn't imagining things and this was definitely not a dream. Suddenly, a rough, powerful voice rang out.

• I didn't think that an angel could end up in the dungeon where you had done such a misdeed.

If you take an angel's wings, you can get them back. But for them to return, you must admit your innocence, and then the wings will break through any walls and return to you.
