Toshio Shimura

"Sakura, sakura, no ya ma to Satano."

Professor Shimura singing an old lullaby.

Professor Toshio Shimura was a Scientist working at the Roarke 279 Research Facility on The Planet Bliss. He began experimenting with Piranha Locusts and turned them into a more hostile species. He dubbed his creations the Kiseibya, supposedly translated as Parasite Saviour. He sacrificed himself to the original Kiseibya so he could live on through their children. (BFA: Enemy of the Daleks)
