You cannot fight Puppeteer. He only appears during dialogues. You will fight random ninjas during Ascension mode which is unlocked after clearing 12 tournament rounds in Act II. Note that Ascension is not available for Windows or SF2 Special Edition.

As for Tempest Rage, from the Enchantments page:

"Every successful hit gives a chance to grow a blue aura around Shadow that can stack up to four times. When in full glow, the next unblocked hit will deal 400% more damage and knock the foe a great distance. However, taking hits will give a high chance to reduce aura stacks. An opponent's throw is guaranteed to reduce one stack."

In short, hit your opponent but avoid being hit yourself to gather a blue aura around you. After the aura is fully charged your next hit will do massive damage to the enemy.
