I think the Noah side of Tyki looks like Neah more....because we havent seen Neah's human side yet....but then we don't know Neah's noah name either
But ya I feel I'm refering to the Noah more....it was just an idea I had XD
Now that I think about it this would imply that Sheryl is also related to Neah if we're thinking of the noah....unless he's only a half-brother to Tyki's noah....
But then Tyki himself (human) would have been born first then his noah would have awakened at some point in his life, if I'm not mistaken the noah are 'chosen'
Maybe it's Tyki's human side that is Neah's son? Tyki would have been born after Neah died, maybe that's why Tyki is the noah of pleasure?
