This is Wolfen Ninjaratzu, Kao and the late Kia Stealthinja's son. The poor kid had the tragedy of witnessing the death of his mother when he was around 13 and while normally a Starmaninjian will revive after they die as if nothing happened, Kia was not to return to the Starmaninjian world because Kiara succeeded in her goal of finding her true father after so many years. However, she was aware that she had a child, Wolfen, and knew that he couldn't be left in the dark about his mother's true identity for long. Going against her own protocal, she told him and made it clear that the goddess he knew of "Solera" was actually Kiara Ratzu, and Kiara was his true mother, Kia being just an avatar she used to revive her father. It took a short while for Wolfen to accept the fact that he was the son of one of the creators of the universe, but Kiara made a promise that to apologize for the tragedy, she would set the portal to her home in the goddess dimension inside of Wolfen, that way, he will never be away from his mother ever again, even if just in spirit. She kept with her word, as from that point on, as Wolfen adventured, she would pop out of him to amplify his attacks and even converse with him to solve problems and figure things out. Whatever Wolfen experiences, Kiara will feel the same thing impact her home. It reminds her constantly of how connected they are.
Wolfen becomes the husband of Rhozia Rhadozia and almost like father like son, swears to protect her at all costs (despite her being stronger than him). They form a very close bond with each other, in that even though Wolfen can't understand a word she says becuase she exclusively speaks Botanian, they still feel as if they know exactly what the other is saying, in ways that words could never fully convey.

Enjoy!
Trivia: Wolfen's story is extremely depressing, but it kind of is a reminder of what I felt when my grandfather passed away. I decided to keep it because it helps emphasize the point that death does not have to be the final goodbye to someone you truly love. Even in a world where you can't permanently die, it's still something that's highly respected. They take life and death very seriously, just as I do IRL.
