Arunaru said that he might work on Atlach-Nacha, but he would need to finish it first. Sadly, he stated that he could not focus on reading visual novels lately, so it might take a little while.
Arunaru's course of action is quite unclear as of now, but as far as I'm concerned, he isn't translating any of the games right now. I guess he's taking a break after translating Kichikuou Rance.
The games that Arunaru plans to translate, if he ever translates again, are Toushin Toshi III and Atlach-Nacha.
It's unsure if any of them would work on it.
The demo, however, was translated, as far as I'm concerned.
I'll try to confirm it later.
Thanks. I'm not the translator though.
Translators are 2.0 Translations and Arunaru.

I don't think they're recruiting though.
