Synopsis

The assignment, curious to say the least, comes directly from Goemon himself. The late Kuranari’s will stipulates that whoever unravels the "mystery" and discovers his inheritance is entitled to it. Lupin accepts the challenge of deciphering the cryptic clues. However, the Fuuma Ninja also scheme to claim the treasure for themselves. The culmination of the struggle for the secret ends atop the castle tower. Where lies the legendary sword, Tsukikagemaru?
