Heloise has always understood Felix's statement that "you don't need to treat me as a 'human'" as being of the same nature as her own often-stated "apostle of the Nefarious Tiger King."
However, after "colliding" with Felix's indifferent attitude, she suddenly realized that what Felix had said was the objective fact.
The "Messenger of the Benevolent Deity" is not a 'person' chosen by the Benevolent Deity, but a subordinate dispatched by the Benevolent Deity from the realm of gods to the Prison Star world, hence the title... Felix, from the very beginning, was not of the same world as her - so thought Heloise.
— (In that case, what about the rules of our tigermen tribe?)
Heloise didn't have any ideas for a moment, so she simply responded frankly to Felix's question.
