Inside the rift and beyond is a nightmarish world of saturated, malicious chakra called Ten-Ja. Inside Ten-Ja is more than a super-massive amount of demonic chakra. This world is home of the Four Guardian Beasts of Hell's Gates, four monsters made of the chakra that can rival the power of four Tailed Beasts. However, whomever his swallowed by the rift is either already dead, killed upon the of the entry of the rift and touching the dark chakra, or is absolutely thrown deep within Ten-Ja and is never heard of again.
