Rennigan doesn't grant Rikudo Chakra, even though it originates from Divine Fruit. Similar to Wood Style or Lava Style.Doesn't the Rinnegan consist of Rikudo Chakra? I thought that can harm the TSB? Or do I mix things up here?
Madara awakened Hagormo's Rikudo Chakra which granted him Rennigan, not the other way around. Meanwhile, Toneri awakened Tenseigan which granted him Rikudo Chakra. It's the reverse.
