Description
Blood Seal ~Eternal Mermaid~ is the twenty-third Made-for-TV Movie in the Lupin III anime franchise. It debuted on December 2, 2011 to a modest viewing audience.
Made to celebrate the 40th Anniversary of the Lupin III franchise on television, the special brought a number of changes to Lupin. The first notable one is the major art style changes to the Lupin characters; past specials for the last decade had relied on designs largely derived from Shin Lupin III, the second TV series. TMS Entertainment (originally Studio Telecom), who was involved with the early days of Lupin, was brought back to do the animation for Blood Seal, and accordingly the designs were redone to evoke the early years of the first "green jacket" Lupin series and the proto-Studio Ghibli designs used in The Castle Of Cagliostro.note
The second change was the first major shakeup of the Lupin cast since Kan'ichi Kurita took over the role of Lupin in Farewell To Nostradamus, following the death of original seiyuu Yasuo Yamada. It was announced with this special that the long-time voice actors for Zenigata (Goro Naya), Fujiko (Eiko Masuyama), and Goemon (Makio Inoue) had retired; they were replaced with Koichi Yamadera, Miyuki Sawashiro, and Daisuke Namikawa, respectively. With this cast change, Kiyoshi Kobayashi, who plays Jigen, is the only original Lupin voice actor remaining.
The movie opens with Lupin being ordered at gunpoint by crime boss Toudou to steal a precious gem, the Mermaid's Scale, at an upcoming black market auction. Although he succeeds, things go badly wrong when a bomb goes off shortly after he departs. In addition, a perky and persistent 14 year-old popcorn vendor and would-be thief, Maki, begs Lupin to make her his apprentice in crime. Combined with another gem, the Dragon Scale, owned by the sinister head of a medtech company, a mysterious waif of a girl who seems to defy death, and a treasure that Lupin's own grandfather seemingly failed to steal, the gang becomes tangled in a dark and mysterious plot for the treasure of mythological figure Yao Bikuni... and possibly the secret of immortality itself.
