The genin of Konoha are having a sports day filled with races, obstacle courses and of course the relay and the prize is a paid vacation for the winner. Unfortunately Naruto and his stomach are getting him into trouble again.

The official website for the Nanbaka television anime announced that the "Nanfes" event in April will screen a previously unreleased anime special.

The story is set in Shahalta, a tiny European city-state floating in the air with practically no contact with the outside world for years. The government is transitioning from a monarchy to a republic, and to celebrate the occasion, a national treasure exhibition is being held. Lupin infiltrates the exhibition for the secret royal treasures, but not before sky pirates snatch them first.

Mamo hurls Lupin, Jigen, Goemon, and Zenigata 500 years into the past; as two warring factions fight over a legendary shrine dedicated to time travel, Lupin must find a way to survive the past to ensure his future.
