Espera que la fumada es mayor
When teenage reporter April O’Neil has a clandestine meeting with Tsunade, the leader of the Hidden Leaf Village, it garners the attention of Naruto, Sasuke, Sakura, and Kakashi. They aren’t the only ones who are wondering what the two women were discussing, though. The sinister Foot Clan have their own interest in April’s visit, as they think she might hold the valuable information on mutation research being conducted by the scientist Baxter Stockman. With April caught between the forces of the Hidden Leaf Village and the Foot Clan, it can’t be long before the Teenage Mutant Ninja Turtles show up to lend her a hand!
