Trivia

 * His name means "purity" or "innocence".
 * Muku is very similar to Sasuke Uchiha, with Muku resembling Sasuke. Both using Fire Release. Similar to Sasuke at the beginning of Part II, they only felt hatred for a family member and no other emotion, and with the death of that family member they both grew stronger. Muku also feels that bonds makes one weak similar to Sasuke. The movement Muku used to attack his father was similar to the movement Sasuke uses, when using the Chidori.
