Yoshiki Takaya, the manga artist behind Bio-Booster Armor Guyver, has delivered a sobering message to fans through the newly released Blu-ray edition of the live-action film Guyver 2: Dark Hero, distributed by Toy Robot. In it, he reveals that a cerebral infarction has left him with lasting physical and cognitive impairments that may permanently end his career as a manga creator.
Takaya’s Message to Fans
“I suffered a cerebral infarction, and paralysis remains on the right side of my body. There is also damage to my brain, and as a result my concentration and judgement have declined, while my short-term memory has become unreliable. To all the fans, I am truly sorry, but I do not believe I will ever be able to take up the pen again.”
The Blu-ray release did not specify when Takaya suffered the stroke. The artist had already placed Bio-Booster Armor Guyver on indefinite hiatus back in 2016.
A Long Publishing History
Takaya launched Bio-Booster Armor Guyver in Tokuma Shoten’s Shonen Captain magazine in 1985. The series later moved to Kadokawa, running in Monthly Ace Next from 1999 to 2002. After a break, the manga resumed in Kadokawa’s Shōnen Ace in 2007, then transferred to Young Ace in 2012 before going on hiatus in 2016.
Films, OVAs, and Anime Adaptations
The manga has inspired numerous adaptations over the decades:
- A 1991 live-action film directed by the late Screaming Mad George
- The 1994 sequel Guyver 2: Dark Hero, directed by Steve Wang
- An OVA series that ran from 1989 to 1992
- A television anime series that aired from 2005 to 2006
Internationally, Viz Media published a portion of the manga in English between 1995 and 1998. Manga Entertainment released the OVAs in North America, while ADV Films and later FUNimation Entertainment handled distribution of the TV anime.
Fans around the world have expressed their sorrow at the news and continue to send their well-wishes to Takaya as he copes with his condition.
