Reiji (レイジ) is a character in the Keroro Gunso anime. Reiji is introduced as part of the singing dancing idol invader unit, Operation Maru-Otsu (〇乙). However, he's actually an android remote controlled by Giroro.
Reiji is Giroro and he makes little effort in hiding his personality. In spite of being a self-proclaimed dancing and singing idol invader, he's quickly seen polishing his weapons like usual.
Kururu researched tastes of Pekoponian girls and created 5 androids that fit their preferences.Giroro controls Reiji using the Invasion Substitute System through a special control room and full body suit hidden inside the Keroro Platon Headquarters.
In episode 320, the platoon invade using the android suits, only to be surprised when Natsumi Hinata easily bows down to them with little resistance. She praises Reiji's knowledge about weapons and military weapons, saying she respects him for it since she doesn't know much about that, which is a big contrast to her usual dislike of Giroro's weapon mania.
Eventually, the second phase of the plan is put into action. Reiji and his friends tell Natsumi and their manager has been challenged by a Pekoponian Rare Beast Hunter and will go on a long marathon due to that. Without him, they have no place to stay. Quickly, she shows the headquarters of the Keroro Platoon to them, and tell them they can stay there since there's no one there. Reiji quickly protests, saying that someone must live there. However, Natsumi calls Keroro and the others worthless garbage, before saying that she'd easily let the idols invade.
Furious with her behavior, Akira and the others break character and accidentally drop a false wall, revealing their hidden command chambers where the Keroro Platoon actually were hidden. They accuse her of letting anyone invade if they're hot, but in response Natsumi just furiously beats them up.
- All the Operation 〇乙 members are based on Gundam Wing characters. Reiji's appearance is based on Duo Maxwell.
