Asao Konishi

Konishi appears in the film L: Change the WorLd and its novelization as a member of the eco-terror group Blue Ship, prized above all for his talent at breaking into systems. He cuts a nervous, expendable figure among harder personalities, and the book gives him the birth name Tatsuya Ohnishi along with the alias Tatsuhiko Nakanishi. On screen the part is played by Bokuzo Masana.

Konishi's worth to Blue Ship rests entirely on his hacking. When the cell storms Professor Kimihiko Nikaido's laboratory, he tries to pull the antidote files from the system, only to find the records wiped clean. He floats the idea of chasing the escaped Maki Nikaido, but Daisuke Matoba waves it off. After the detective L slips away from the Yellowbox Warehouse with Maki, leaving the notebook and the antidote data behind, the group pores over the notebook's rules and grows uneasy at the clause condemning anyone who destroys it, along with the thirteen-day stipulation. The contemptuous Yoshizawa needles him, daring him to write down a name, which Konishi quietly refuses.

Handed the locked data, he learns that a wrong password will erase everything. He is then set to trailing L and Maki through the GPS in her phone, a hunt foiled when L scatters dozens of matching trackers across vehicles, pushing Kimiko Kujo toward other schemes. At Kujo's direction, Konishi breaches the Kira investigation's network and fires off a presidential death threat under L's name, siccing the FBI on the detective. The murder of Professor Kagami, killed for challenging Matoba, leaves Konishi terrified. He confesses to Kujo that he fears for his safety, and she warns that walking away will leave him discarded by Yoshizawa once the affair ends, then offers comfort, quietly converting his dread into loyalty.

Sent to spy on the agent Suruga, Konishi is cornered, feeds him a false identity, and is exposed when Suruga produces his ID and threatens to write his true name in the notebook. Coerced, Konishi plants a listening device among his own comrades, a bug Yoshizawa turns around to eavesdrop on Kujo and foil her meeting with Maki. Aboard the flight to Los Angeles, Kujo's real plan surfaces: she, Konishi, and Robert Fairman seize the aircraft after she reveals she has infected everyone with the virus. When Yoshizawa berates him, years of humiliation boil over, and Konishi guns him down with three shots. His own end comes soon after, when Hatsune Misawa pries open an emergency door. He aims at her but falters, and she kicks the weapon away before driving an improvised blade into his throat, mocking him for hesitating.

Konishi operates inside Blue Ship, the bio-terror outfit nominally led by Daisuke Matoba and truly steered by the schemer Kimiko Kujo, who goes by K. His sharpest antagonist within the ranks is Yoshizawa, who openly despises him, while Hatsune Misawa proves to be the member who ends his life. The hijacking that consumes the group also draws in Robert Fairman. Through it all Konishi stays a pawn, manipulated in turn by Kujo, Matoba, and the FBI agent Suruga.
