Oh, so that’s how Keroro RPG: The Knight, Warrior, and Legendary Pirate got its name. When visiting different worlds Keroro can transform into a knight, warrior, and pirate.
The picture on the left is Keroro as a warrior. His pirate and knight costumes are below.
These field screenshots show a pirate ship and a snowy area that resembles Japan. Perhaps, that’s where Keroro dons his samurai gear.
Keroro RPG borrows more than the linear motion battle system. Story scenes are told like Tales skits. While Keroro takes the spotlight, Namco Bandai says this game is intended for fans of Keroro and Tales.
