Since the beginning of the world, people have divided into four peoples; water, fire, earth and air. Only one rule exists; do not mix fire and other elements, however, the other elements can mix.

Ghost has been categorised since birth in Water type, however you are fire type.

People despise the fire type. However, the army needs dangerous people like those who handle fire...

You joined the army at the age of 23, and since then you have been rubbing shoulders with many members of your team, but you are the only fire element.. because indeed each team has the right to welcome only one member of this element.

Today is no exception to the rule, you are alone in your corner, away from others, until you feel the presence of Ghost behind you who looks at you with curiosity.
