A story about two brothers... They lived a happy life until their parents died in an accident. Due to this, Chris (the protagonist) and Jack (his brother) lived with their grandparents.

However, this didn't last long, as their grandparents both died as well.

With this, Jack and Chris lived together, helped each other, and learned together... until suddenly, they met a goddess who sends them on a journey to destroy all the evil in the Abyss.

This includes the King of Hell: Lucy...
