At the conclusion of each mission your ninja techniques are reviewed. Your score and rank will depend on how many enemies you killed and under what circumstances. If you score a high rank your ninja items will be increased. Score the highest rank, Grand Master, and you will be rewarded with a special Grand Master item per mission.

The fact that you only need 450pts to gain a Grand Master ranking allows you to deduce two formulae regarding how many times you can be spotted and still gain the highest rank. Suppose a mission has x enemies. Then use these formulae to check how many times you can be spotted, s :
Formula 1 | s < | 20x – 150 |
45 | ||
Formula 2 | s < | 20x – 150 |
30 |
where Formula 1 calculates s assuming you normally kill any enemy who sees you, and Formula 2 assuming you stealth kill any enemy who spots you. Note these formulae assume you kill every enemy on the level.
