This anime is based on one of Sony's greatest yet most underrated franchises: Ape Escape. It's called サルゲッチュ～オンエア～(Saru Get Chu ~On Air~). The 2nd season to the show is called サルゲッチュ～オンエア～(Saru Get Chu ~On Air~ 2nd). The 1st season has 26 episodes, while the 2nd season has 51 episodes.
Although the 1st season has already been subbed, the 2nd season has never been subbed after the show ended 4 years ago. It was never released outside of Japan and it hasn't got an announcement of a DVD release for a while. For the past few years, fans of Ape Escape and people who watched it have been screaming for the 2nd season to be subbed.
It's very hard to find the 2nd season episodes nowadays, since most sites have the 1st season episodes. I have been collecting nearly every episode for the past 5 years since the show was first aired.
People once uploaded the 2nd season episodes on Youtube, but they were easily taken down by Shopro and XEBEC so I wasn't able to get all of the episodes. Although I have been learning Japanese for 5 years, I still find it hard to translate every single dialogue in the episodes.
For those who do not know this video game franchise very well, this is a great way to introduce yourself to the Ape Escape games. I, myself enjoyed the show and I have been a fan of Ape Escape ever since the day I got Ape Escape 2 in 2003. If you have played Disgaea before, you will hear Etna(Disgaea)'s Japanese voice actress: Tomoe Hanba.
For anime fans who never heard of this show, you may recognize some of the voices in the show such as Naruto's current Japanese voice: Junko Takeuchi and Soifon(Bleach)'s former voice actress: Tomoko Kawakami.
If you are interested in subbing the 2nd season of this anime, I will be glad and honored to give you all of the 2nd season episodes that I have in my computer.
Here is one of the 2nd season episodes on Youtube:
Thank you very much from the bottom of my heart.
