Yū Shirogane (Japanese: しろがね遊 Shirogane Yū) is the main character of Pocket Monsters Platinum: Aim to Be Battle King!!. He is a schoolboy who plays the video game Pokémon Platinum Version, aiming to become the Battle King.


Yū's goal is to become the Battle King, and will try very hard in obtaining that goal. He is also prepared in most situations as he gives items to his Pokémon and chooses the right Ability in a situation.


Yū debuted in the first chapter of the manga. He recently got his Platinum game and immediately trades his Shaymin in exchange for a Bidoof. It became disobedient towards Yū afterwards. Yū's rival, Shin, arrives and mentions that he doesn't have enough badges to make the Shaymin become obedient. This made Yū upset that he wanted to challenge Shin to prove him wrong. However, Shin declines since Yū only has one badge. After Yū obtained more badges, he requests to battle Shin in which Shin accepts this time. During the battle, his Shaymin was able to listen to Yū especially when both sides were down to one Pokémon. Yū was able to win with the help of Shaymin.

Following the battle, Yū heads to the Battle Tower and trains by battling various Pokémon. He gets partnered up with Shin when they battle two Trainers and their Magmortar and Electivire. Their opponents easily defeated them as Yū and Shin were not in sync with each other. Yū and Shin head home to work on new strategies to defeat the duo. The next day, Yū and Shin have a rematch with them and unlike last time, Yū was able to defeat them with Infernape. Yū then battles a Trainer with a Groudon and Vaporeon. He takes advantage of his Pokémon's Ability by swapping them with his Bronzong's Skill Swap which helped him win the battle.

He witnesses a Trainer with all of the members of the Pokémon of Myth. The Trainer easily defeats Shin with only Dialga and Palkia. Yū takes Shin's place in battling the Trainer. Yū was having trouble with him as his Infernape was taken out by a combined DragonBreath from Palkia and Giratina. Despite the obstacle, Yū managed to win. Yū gets invited to a tournament to determine the true Battle King. He goes to it and manages to gets 100 wins. A Trainer with a Pikachu hat watches and becomes interested in him.

Yū has his second rival battle with Shin. Unlike last time, Shin had some improved strategies that put Yū at a disadvantage. However, Yū's trump card, Quagsire, managed to defeat Shin's Tyrogue and Wailord. After the battle, Yū goes on to find out that the Trainer with the Pikachu hat turned out to be the current champion of the tournament. He appears to be tougher that Yū expected, preventing Yū's Pokémon from doing anything using his strategies. After both sides lost two Pokémon, Yū was down with Infernape while his opponent had a Snorlax left. As Snorlax used Belly Drum to maximize its attack, it became stronger that Infernape. One Flare Blitz from Infernape managed to finish Snorlax off, which made Yū the winner as well as the new Battle King.
