Features
Catgirl Downloader

The Catgirl Downloader is an application which allows you to download images of nekos. It also has an NSFW toggle, which, I think, makes Nyarch Linux the only OS
to come with such a toggle by default. Maybe some beta of OS/2 had one, but I don't know.
Waifu Downloader

Waifu Downloader is very similar to Catgirl Downloader, but you can download pictures of Waifus instead. It also features the NSFW toggle.
Nyarch Assistant
Nyarch Assistant is an AI Assistant
It doesn't work on any of my Laptops because they are too old, so I don't have any screenshots
Komikku

Komikku is a Manga Reader.
It can be a bit confusing since it offers many services in many languages.
And most of these services host the same content.
Lollypop

Lollypop is a Music Player, which seems a bit redundant since there is also the Gnome Music Player
and VLC already installed. As for Lollypop, It's a decently competent music player I guess.
It can play from online streaming sites, but it only shows albums, not individual songs.
Shortwave

Shortwave is an Internet Radio App. It is included for you to listen to anime and weeb online Radio stations, like Listen.moe,
but you can listen to regular ones too
