That first one is Vagabond Suzuki. The second one is Satoru Ogura.
I do have one suggestion. When you encounter a kanji name, please paste it into our search, and use the English name that our search finds. If this doesn't give any results, and you can't find a reliable reading for the name, then leave it as kanji. Never copy name romanizations from translators.
Another interesting thing: the anime actually made it here as Spirit Warrior, even though the title translates as Peacock King.
