Magic Kaito

Magic Kaito (まじっく快斗, Majikku Kaito) is a Japanese manga series written and illustrated by Gosho Aoyama, that began in Shogakukan's Weekly Shōnen Sunday in 1987. Aoyama put the manga on hiatus after the first two tankōbon volumes were published in 1988, and only occasionally draws new chapters; the third volume was published in 1994, the fourth in 2007, and the fifth in 2017.

Twelve animated television specials based on the series have been produced by TMS Entertainment and aired between 2010 and 2012. A 24-episode anime series titled Magic Kaito 1412 (まじっく快斗1412) was created by A-1 Pictures and aired from October 4, 2014 to March 28, 2015.

Plot
On the opposite sidelines from Conan Edogawa, Kaito Kuroba is a normal teenage student whose father died under mysterious circumstances eight years ago. Now in the present, he is made aware of his father's secret identity; a famous international criminal known as Kaito Kid, who was murdered by a mysterious organization because he tried to steal a gem which was also targeted by them. The goal of the organization is to find within a year the Pandora Gem, a mystical stone said to shed tears during the passing of the Volley comet (which happens once every 10,000 years): drinking these tears bestows immortality.

He vows to prevent the organization from gaining immortality, and assumes his father's thief identity as he begins his quest for the gem. His only clues as to the gem's location are that it glows red under the full moon and that it is a doublet: a gem hidden within a larger gem. Thus, it would have to be a relatively large one with a bizarre history, and always stored in a place that never receives moonlight. He thus researches and steals famous priceless gems with odd histories from incredibly well-defended areas, but returns them after the very next full moon as they are not the Pandora.
