Rui Tsukiyo

Rui Tsukiyo (月夜涙) is a Japanese novelist from Gunma Prefecture.

Career
In 2014, Tsukiyo began releasing his first series Elf Tensei kara no Cheat Kenkokuki (エルフ転生からのチート建国記) to the web fiction site Shōsetsuka ni Narō. It would win the Monster Bunko Awards Grand Award in 2015 and later began publishing in July the same year under Futabasha's Monster Bunko label.

Redo of Healer too initially begun as a web novel in 2016 before officially releasing in 2017 under Kadokawa Shoten's Kadokawa Sneaker Bunko label. It was later adapted to a manga and then an anime.

The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat began as a web serial in 2018 and saw an official release in 2019. It too got adapted to a manga and an anime. Both the light novel and manga were acquired for English publication in 2020 under Yen Press.

Writing style
His work is known for being dark and violent, containing themes such as rape, murder, and revenge. Tsukiyo states such stories emphasize the protagonist's actions and that he prefer protagonists who "don't hesitate."

In talking about Redo of Healer in particular, Tsukiyo says that it was influenced by revenge stories popular on Shōsetsuka ni Narō at the time and that the series was "born out of the desire to make an extended revenge story." He also says the series was a gamble, hoping the controversy generated would make it sell.
