ah, so they use " i cast universal translator Bullshit" to fill the language plotholes lol. been wondering since the card introduced like "aint this card has description on it? how the fucc isekai people can read it?" some people suggest that many reincarnators has influenced languages in isekai making them understand the basic English or Japanese. but pulling a magic translator card like this sure convenient (in fact, why not? this is magic fantasy world after all lmao)
also who the fucc putting that dangerous items next to items for sale???
