"I"'s relationships

"I" (ぼく)

Voiced by: Yūki Kaji^[5]

"Nonsense Bearer" (戯言遣い, zaregoto tsukai). The narrator of the Zaregoto series, people call him by all sorts of nicknames beginning with the phonetic pronunciation of his family name Ii (井伊) such as "Ii-chan" (いーちゃん）, "Ikkun" (いっくん), "Ii-tan"　(いいたん). Birthday is in March, birthplace Kobe. His real name was never revealed, but in Hanging High School he played a name-guessing quiz with Shiogi Hagihara (later mentioned), but the answer was not revealed either.

After graduating eighth grade, he entered the ER3 system (a type of genius raising school) and went to Houston, Texas for five years; with the death of his good friend, Magokoro Omokage, he withdrew from the system. Now, he is a resident of the Antique Apartment, second floor, and also a student in the Rokumeikan Private University. He consistently downplays his own abilities and extremely apathetic. He inevitably ends up solving the mysteries he encounters but at the end of each mystery realizes his activities were meaningless. Many characters he encounters including himself are morally grey and representing extreme philosophical ideals.

In the first book, Jun was invited to help solve the murder on the island, but she does not appear until the novel's epilogue. At the beginning of the book, Ii-chan presumes that Aikawa is a man.

She died in an airplane accident.

The Residents of the Antique Apartment

Can never stop getting into trouble with the guests at a new work place, but still finds a job teaching at a kendo school momentarily.

Miiko is really concerned about "I"'s personality. "I" confessed to Miiko, but she reserved it saying she'll consider about it if "I" becomes a better man.
