In a cabin deep, deep within the forest, the happiness of a poor but peaceful rabbit family was shattered on the day the protagonist reached adulthood. It was during a brief moment away from home to gather food. Upon returning to the cabin, nothing remained but unrecognizable lumps of corpses, entrails scattered across the floor, and a single, blood-stained note.

"Thank you so very much for assisting me with my foolish meal."

On that day, the innocent rabbit died. All that remained was a blood-teared desire for revenge: to find that eccentric freak among the countless wolves in this world and tear his throat out.
