It is an executable that boots Kali-Chroot (one Installed with Nethunter apk) in Termux.
NOTE: This is not same as Nethunter Rootless.
If you have ever used Nethunter-Rooted, then you would have definitely come across Nethunter-terminal. Nethunter-terminal is one of the good interfaces but, it doesn't support that much customizability when compared to other interfaces such as Termux.
If you ever took a fancy to start the Rooted Kali chroot in termux but faild. Then this is the right place.
