In the live action movie Death Note, Light comes down from upstairs and tells his sister Sayu "be careful of strangers." Then Sayu says "i will." And then she says what sounds like itikimasu. (And then light's mom said something back to Sayu) What does that mean? (if thats even what Sayu said) I was watching death note last night in japanese with no subtitles trying to see how much japanese I could understand. And it didn't sound like "sayounara." (The only way I know how to say goodbye in japanese)
