Fuyuki as seen in Episode 3
|First Appearance||Episode 1|
Fuyuki lives with his mother, Aki Hinata, and his sister, Natsumi. He doesn't seem to have many friends, so he was eager to befriend Keroro when he broke into their house. Not much else is known about him, besides his general idiocy and dubious attention span.
Fuyuki gets along with everyone in the series. He is arguably closest to Keroro, who has been shown to genuinely care about Fuyuki.
"Tear down this school!" - Episode 1
Keroro: "Didn't I tell you? I'm an alien invader."
Fuyuki: "I wanna be your friend too!" - Episode 1
"WHEN DOES THE MAGIC HAPPEN?!" - Episode 3
"Speed lines are cool!" - Episode 5
- Fuyuki's voice and occasional over-the-top demeanor is a result of Thorn making fun of child voice actors auditioning for various Sgt Frog projects around YouTube.
