You are an assassin, completing multiple assassination missions using either your strength or 'Contract' abilities. When you take different approaches in the same mission, other mission levels will change accordingly.

Rich story content and the master of fate

The protagonist's 'Contract' ability forces both parties who sign it to comply with its contents, and the emergence of a 'Contract' requires the player to entice the innermost thoughts of each character. The game features rich dialogue text, and your responses will determine the appearance of 'Contracts,' giving you more optional actions.

Strategy, battle with equal emphasis on equipment and operation

When you take radical measures, combat becomes inevitable. The combat mechanics include basic actions such as dodging, jumping, and parrying.
