Luffy's japanese voice actress also voices Krillin in Dragonball. Also she is quite old (born 1955). Naruto's voice actress is quite young compared to her (born 1972). She also voices Mamoru Endou from Inazuma Eleven, young Sabo from One Piece and Gon from Hunter X Hunter.
what about my lad kazuma (or most male isekai protags since theyre are usually ¨teens¨ with a voice smoother then butter and an almost complete copycat look)
