Yu Yu Hakusho
Author Yoshihiro Togashi stated that he began working on "Yu Yu Hakusho" during a period of time around November 1990, though he forgot the exact time. He had recently completed the serialization of his romantic comedy "Ten de Shōwaru Cupid" in "Weekly Shonen Jump". Having felt somewhat intimidated by some of his more popular fellow authors during this manga's run, Togashi realized he would need to create a fighting manga to both gain popularity and write something he enjoyed. As a fan of the occult and horror films, he desired to write and illustrate a new manga based on his interests. Togashi had previously published an occult detective fiction manga titled "Occult Tanteidan", of which he referenced positive reception from readers as a reason for continuing to create manga. When first producing "Yu Yu Hakusho", he did not have a clear idea of what he wanted to call it. He used the tentative title "How to be a Ghost" while presenting rough drafts to his editors. Once given the go-ahead to begin publication, Togashi proposed "YuYu-Ki (Poltergeist Chronicles)" for the title, as there would be battles with demons and it would be a play on the title "SaiYu-Ki". Because a series with a similar name ("Chin-Yu-Ki") had already begun publication, Togashi quickly created an alternative: "YuYu Hakusho (Poltergeist Report)". He commented that he could have used "Den (Legend)" or "Monogatari (Story)", but "Hakusho (Report)" was the first thing that came to his mind. He contiguously developed the names of the main characters by skimming through a dictionary and taking out kanji characters he found appealing. "Yusuke Urameshi" is a pun, "Kazuma Kuwabara" is a combination of two professional baseball players, and "Hiei" and "Kurama" are "just names that popped into [Togashi's] head". When he introduced the latter two characters in volume three, the author had early plans to make Kurama a main character but was not certain about Hiei.
