Malisanka
The Huntik team is assigned a mission in Japan. During it, they are unexpectedly drawn into the world of dead samurai. It turns out that a danger lurks in this other world and only the team can put an end to. Will they manage to earn the trust of the ninjas who live there? What was the reason they were summoned to this world?
I rather recommend being familiar with the plots of Naruto and Huntik to avoid spoilers, but I tried to describe things in a way that allows to every reader to enjoy the story without too many unanswered questions. Also, some elements have been changed for the sake of the story, but you'll learn everything as you read.
