Tranquility passed her basic competency tests fairly early at 12, and refined her Practice sufficiently to handle particularly upsetting material at 16. She is somewhat experienced now, at 23, but looks fairly youthful aside from the composure with which she carries herself - she appears only slightly older than the oldest child, and would not seem out of place among them.
Uh. Hmmm. She would like to answer honestly. But she doesn't know an honest answer. Or have any idea what the honest answer could possibly be. And "I don't know" would sound very suspicious.
Well, the truth is usually the least complicated lie, but she still isn't excited about the possible results. (Also, "Ohtori Akio"? What does that mean? She knows some people draw their names from conlangs, but usually they'll explain it in their introductions, and "the chaperone of a skool(?) trip" doesn't seem like a name one would give themself on a permanent basis, and it doesn't match the phonotactics of any language she's heard before.) She bows slightly, and then speaks.
"It is good to meet you, Ohtori Akio, and I apologize for any inconvenience. I am Tranquility of Sunflower Creche. I am not exactly sure how I got here either - I just woke up on the beach - and apologize for this oversight."
Her attention is mainly on navigating the potentially risky social interaction, but fragments are still searching for any information about where she is. Does she notice out of the corner of her eye any symbols, statues, architectural styles, uniforms, or other distinctive things that might give her some information about whose mansion this is, or where?
