SAO: Reincarnated with skill [Seer]

My name is Jnanesh Sato, my parents - both are otakus who forced me to be an otaku but we all died cuz my mother was to excited to see MHA S7 ep 3.. yeah it was a very bad gas explosion Next moment i saw I was born to my loving parents Aiko Kirigaya (mother)and Akira Kirigaya (father) and was also born with a status board yup don't worry I checked but yeah there is no system no nothing other than a skill [Omniscience] Then 4 years later I have a brother called Kazuto Kirigaya...yeah I now praise my parents with every adjective I know of 1 years later now I have a sister called Suguha Kirigaya and then 4 years later father died to marshmellow by choking on itand mother died to shock that father died next I as a 9 year old had to survive with 2 other kids... Good thing for me being 1st in my country and no.3 In the World in academics and as this world is not that different from my old one so i became the world's richest and youngest person in record time of 9 years and that was when the story starts with the release of Sword Art Online... And as his big brother of course I will play with him ( of course I trained in some stuff throughout the years) _________________ what to expect system: yeah a very weak one harem: nope multiversal travel(anime to anime jump): yup
