I mentioned this in a previous comment section, but I wanna bring it up again
Fun fact: Kakyoin’s first name is actually Tenmei, not Noriaki
The kanji for the two names is the same, so although Araki-san intended his name to be Tenmei, his editor misinterpreted and wrote it as Noriaki
Araki-san brings this up in one of the volume releases of Part 3, and when Kakyoin signs his name in Enyaba’s hotel, he writes Tenmei as his first name
