Izuru Yumizuru, the author best known for the IS (Infinite Stratos) light novel series, posted a Wednesday blog entry about deteriorating health conditions that are leading to a lack of interest in writing more. Yumizuru posted that the resulting increased medication — around 20 pills on one particular morning — has cause side effects such as general fatigue. Due to an impaired sense of taste, cola and even plain water tastes extremely bitter. Yumizuru is taking sleep medication to battle insomnia, but is experiencing nightmares.

Media Factory's MF Bunko imprint shipped the fifth Infinite Stratos light novel volume in June after announcing that a television anime adaptation was green-lit. Director Yasuhito Kikuchi and the studio 8-Bit are working on the anime.
