Sgt. Frog Season 2 Blu-ray contains episodes 52-103 of the anime directed by Junichi Sato in standard definition on a Blu-ray disc. All episodes feature Japanese audio and English subtitles. Episodes 52-78 also include an English dub.

The comedy kicks off as Keroro tries to take over the Hinata household again, but the season ends with a suspenseful storyline that may mean no season 3! It begins with a computer virus that wipes out data all over the world.

Then, all of humanity freezes in place except for a few select people like Fuyuki, Natsumi, and ninja girl Koyuki. Finally, invaders from space start taking over Earth, and the Keroro Platoon is helpless to stop them. But why would they want to, when the Garuru Platoon vanguard is part of the Keronian army?

Special Features: Clean Openings and Endings, Promos.
