BIOGRAPHY
Asai Sai (浅井西, also romanised Sai Asai and Asai Nishi) is a Japanese mangaka. Their credits cover twenty three works across fourteen years, from 2012 to a title still running in 2026, and all but a handful of them are boys’ love.
The career does not begin there. The first credit is Clover no Kuni no Alice: Kishi no Kokoroe (クローバーの国のアリス ~騎士の心得~), a twelve chapter fantasy romance serialised across 2012 and 2013 and collected in three volumes, followed by a contribution to a Shin Megami Tensei IV comic anthology in 2013 and a second Alice title in 2014. Those are adaptations of women’s romance game properties, not BL.
From late 2014 the work turns to BL and stays there. Nemureru Koi no (眠れる恋の, 2014 to 2015) is the first work carrying a boys’ love classification, and nearly everything after it does too.
Between February 2015 and October 2016 came a rapid run of six single volume books of nine to eleven chapters each, all with BL in the title, among them Kaihatsu BL (開発BL), Trauma BL (トラウマBL) and Gokuaku BL (極悪BL). Alongside them and after them came a long list of one volume works: Shousetsuka no Shitsukekata (小説家の躾け方, 2015 to 2016) and its 2017 companion Shousetsuka no Oborekata (小説家の溺れ方); Mabayui Koi no (まばゆい恋の, 2016); Neko no Kataomoi (猫の片想い, 2016 to 2017); Rakuen wa Te no Naka ni (楽園は手の中に, 2017); Boku no Sensei (ぼくの先生, 2019); the paired 8-nenburi ni Dakaremasu (2020) and 8-nenburi ni Koishimasu (2021); the science fiction tinged Wasureru Kimi to no 300-nichi (忘れる君との300日, 2021 to 2022); and Koi Nanka Suru Hazu mo Nai (恋なんかするはずもない, 2023).
One of the titles is Anata wo Korosu Tabi (あなたを殺す旅), thirteen chapters in two volumes, serialised from 6 April 2019 to August 2025. Two yakuza, Odajima and Kataoka, are sent away together on a trip after the younger man’s mistake, and the trip conceals its real purpose: Odajima has been ordered to kill him. A sequel, Anata wo Korosu Tabi SS (あなたを殺す旅SS), began on 22 April 2026 and is still running.
Two further pen names are アラビックヤマト (Arabic Yamato) and 櫻カヲリ (Sakura Kawori). The birthday is 5 November.
Nearly all of Asai Sai’s twenty three works are single volume books.
Anata wo Korosu Tabi is the long serialisation in that list, running from April 2019 to August 2025 while eight other books were started and finished around it.
Its sequel, Anata wo Korosu Tabi SS, began eight months after the original ended.
In my view Anata wo Korosu Tabi is the natural starting point for a new reader: a finished two volume story with a sequel still running, so a reader can complete the first and then follow the second as it comes out.
