Killua

Is there is any novel for this? really really wish to read novel of it, translated if there is please in English or Russian, if any links

Romance very little, a small hint on harem but no love relationships progress, also i consider this one of the best MC development from being someone average to personality building and changes developments of MC very interesting scared of everything to develop courage becoming smarter and stronger slowly build unlike scurlture story fully no deep greedness, his relation with his parents evolves in very good ways as well taking care of his family needs and his family stay humble and helping him too i love MC parents and how he changes slowly from being later on control freak believes he is the right one always to be better and better of a person if any read novel will see huge difference from novel and manhwa which much less detailed and missing a lot
