== Trivia ==
* His concept art is designed by Noob_Daddae.
* Isamu Uchiumi will most likely defeat Enzukai, like Yasu defeated Kintoru in Control's Book.
* Isamu Uchiumi is NOT a part of the Masashige bloodline and under a different genealogy.
** Many players thought that Yasu was the main protagonist for Jealousy's Book. However, this is not true as he had finally accomplished what he was supposed to do and freed his family and ancestors, and can live peacefully.
** It is also confirmed by MUCDICH that each book will have a different MC and storyline.
* Unlike Yasu and Keiko, Isamu Uchiumi does not seem to be under a cursed bloodline or any curse in general. It's also stated that ancestry and bloodlines will not be involved in the story of Jealousy's Book.
* Isamu Uchiumi is the pathologist of his older brother, Senzai Uchiumi.
* Isamu Uchiumi used to have a different name, in which it was "Muramachi Kokomi" by a theorist in the official Discord server. This was later changed due to the fact that she wanted it to be named after Sangonomiya Kokomi, a Genshin Impact character.
* Isamu Uchiumi is one of the few characters in The Mimic who is a human and does not have a last name ending with Masashige. The others are Rin Tsushima, Mio Tsushima, Chihiro Amano, MC3 and MC 4. The farmer and the Dead Geisha do not count since their family names are yet to be known.
** Kaeda Akiko's name also does not end with Masashige; however, due to The Mimic: Origins being debunked, the canonicity of her existence in the current lore is questionable.
* Similar to Yasu, Isamu Uchiumi has parents, but due to the lack of proof of ancestors, they may be irrelevant/unseen.
* Isamu Uchiumi's official name was formerly Tyra. However, MUCDICH confirmed that Tyra isn't going to be his name and was scrapped.
** This includes the other information planned such as nationality, gender, and country.
* It was confirmed by a lore writer states that The Second MC's official name is "Isamu Uchiumi," along with an information that he is a male.
* Isamu Uchiumi has a brother named Senzai Uchiumi, a major character in the plot of Jealousy’s Book.
* The name Isamu is a masculine name in Japan. While it can be written in Hiragana or Katakana, the following kanji meanings can either be "Bravery," "Courage," "Merit," "Gallantry," or "War."
** Similarly, his surname Uchiumi, by their own meanings, mean "inside" while the second means "sea," but more commonly refers to the ocean itself.
** Isamu may have his surname as Uchiumi on purpose because most of Jealousy’s Book takes place in the ocean.
* Some people may assume Isamu should be 23 because he was born in 1999 and Jealousy’s Book takes place in 2022.
** But, he is actually 22 because he was born on July 15, 1999 and Jealousy’s Book takes place on March 27, 2022.
** March 27 is before July 15 meaning he hasn’t turned 23 yet while Jealousy’s Book takes place.
* Isamu's occupation is confirmed to be a detective, who probably did the autopsy for Senzai, since his name is written on the report.
** Many people before have speculated Isamu to be either a forensic pathologist or a forensic scientist. This is not true however, as Isamu only has to go under the title as a pathologist in order to have full obligations to perform an autopsy on his brother's body.
** Furthermore, the office Isamu arrives in appears to have a morgue for some reason.
* Isamu ends up in Jigoku/Hell right after getting his heart ripped out (which ultimately led to his death). This heavily implies that Isamu might've done some very sinful stuff, either during or prior to the events of Jealousy's Book taking place. Though, we do not know what specific sins he could've possibly committed yet.
** This information could further relate to the line where Isamu states that he has regrets he wished to tell to his older brother. So the commitment of his sins could possibly have something to do with Senzai as well.
* Isamu is the first ever protagonist to have his name being mentioned directly in the game.
* Isamu is also the first and only protagonist so far to die in The Mimic's main storyline
** But currently, we can see that he ends up in Jigoku right after his death. So we most likely will still be playing as him in the upcoming chapters.
** Some players also thought that Jealousy Chapter 2 was the end of Jealousy’s Book because Isamu died - which isn’t true.
