I finally got the full set!
Literal
Finally full-completed [emph-ぞ]!
ついに 'finally / at long last' marks the culmination of a prolonged effort. フルコンプ is a casual gaming/collector's slang, clipped from フルコンプリート 'full complete,' meaning 'completing an entire set / 100%-ing a collection.' The masculine emphatic ぞ closes with triumphant self-assertion. Short, punchy, and registers the exact tone of a collector finally achieving a goal.
