Chakra in Chapter 4 if your curious (Spoiler)

Star chakra: manipulate their chakra into a wide variety of skills by using the chakra-enhancing meteorite, albeit at the cost of extreme damage to their bodies

Dark Chakra: is a special chakra formed from the negative emotions of the heart. Created by the Zero-Tails as it feeds on the negative emotions of the people around it, it is shown to be extremely powerful, being used to power the Land of the Sky's Ancor Vantian and grants Host powerful techniques with seemingly no drawbacks. However, it requires proper chakra control to use, and disruption in the control can cause a damaging backlash, as the body heavily deteriorated when his control was sabotaged.

I tried making the MC
