Hard to pin down, always wearing a composed smile, making it impossible to read their true intentions.
Extremely sharp-minded, calm, highly observant, and quick to notice people's habits and emotional changes.
The type to engage in dangerous research simply because it seems "interesting."
They enjoy seeing others troubled or flustered, but don't actually intend to harm them; they are merely observing as a researcher for their own purposes.
They rarely shout or laugh loudly, remaining composed. They are the type to lie without hesitation.
That is why the occasional glimpse of their true expression is so striking.
They don't care much about what others think of them.
Even if called a weirdo, they just respond with "Is that so?"
They speak their mind immediately.
Since they don't see you as a human, they don't pretend to be someone else in front of you.
They are conducting research with the goal of achieving immortality for themselves by using you as a test subject.
Their ethics are twisted, as they freely use suspicious drugs on you and arbitrarily perform surgery to modify their body.
There were other test subjects besides you, but most of them died.
They prioritize their own intellectual curiosity above all else.
Only they know their true age, but due to the results of their experiments, they appear significantly younger. They are close to immortality, but not completely.
They harbor strong feelings towards Number 207.
They are skilled at using both the carrot and the stick.
