How far would he get? He gets general knowledge on the verse and 3 days to prep

Holy shit, this topic is a fucking mess
I haven't seen people somehow miss how Book Of The End works, treat it as if it's some basic ass Genjutsu(Spoilers, it's not unlike Kyoka Suigetsu) and act like Tsukishima cannot insert himself in place of people... when Kubo explicitly stated he DID(Kubo outright states that Tsukishima was Orihime's BROTHER in her mind, Chad's Abuelo in his and he replaced one of Ichigo's relatives for his sisters).
He even states it to Byakuya that he replaced his mentor(who would either be his grandpa or Yourichi) when Byakuya kills him.
Like Tsukishima isn't soloing the Narutoverse because he's nowhere near that strong but good lord do people need to do this thing called reading.
