um so first off in the hunter exam tonpa wanted to HAVE FUN. like we can see he was giving out orange juice while KURAPIKA DIDNT want to have fun becuz he was serious the whole time. this contrast between them is so mindblowing togashi is a GENIUS.
next up TONPA represents KURAPIKA when he was a child because he had kurapika's personality where as they were both happy and playful ... i jus.. togashi is so genius
also remember when tonpa didnt fight the guy that pretended to be in the phamtom troupe?? this foreshadows that kurapika is going to fight someone in the phantom troupe.
last but not least tonpa and kurapika are overpowered. The interrogatory which inaugurated this particular interlocution presupposes the existence of an erudite but languorous subclass of Quora participants who are prepared to eschewthe customary virtues of transparency
ok now give me compliments this was hard to figure out considering both are very minor characters
