i just found out something interesting regarding the hidden inventory arc. so im gonna share it.
hidden inventory in japanese is ‘懐玉’ (kaigyoku) which means ‘harboring a jewel’ and comes from an old chinese idiom ‘被褐懐玉’ (hikatsu kaigyoku). the idiom describes someone who has ‘hidden’ great worth, talent, wisdom, virtue that is kept under a humble appearance.
by my understanding this reflects gojo. sure he wasn’t humble but this title refers to his enlightenment. he is ‘revealing’ his jewel, his talent and therefore becoming ‘precious’ like one. satoru (悟) literally means enlightenment.
but now to premature death. premature death in japanese is ‘玉折’ (gyokusetsu).
as you can see both share the kanji ‘玉’ (gyoku), which means gem/jewel or a precious stone like jade.
however ‘玉折’ (gyokusetsu) means something else. it comes from the idiom ‘蘭摧玉折’ (ransai gyokusetsu). its english meaning is somewhat: ‘[the orchid is destroyed] and the jade is broken.’ both orchids and jades symbolize precious, beautiful things. it can also be understood as ‘the breaking of a jewel’.
but this idiom is used to poetically describe the premature death or tragic end of a person who had great talent or high morals.
i believe it refers to geto. he used to be the one with the moral concept of protecting others, but due to the events and the ugliness of humans and the constant pressure, he defected. in words, his jewel ‘broke’, which also marks the death of the person he used to be. suguru (傑) literally means excellence/worth or extraordinary/outstanding.
and if you put both titles together:
懐玉・玉折 (kaigyoku gyokusetsu) translates as ‘hidden inventory | premature death’.
it symbolizes the finding of a jewel (in gojo’s case—his enlightenment) and the destroying and loss of a jewel (in this case geto and his deterioration/defection).
