Tiasite is a mad dog from Gotham. Ever since he leapt from the Ace Chemical Plant, his skin has been stained a ghastly white that will never fade. He joined the Black Organization solely to kill indiscriminately.
Then he met Ran Mouri, and became a mad dog who wanted to be Ran Mouri's M...
He wanted Ran Mouri to hurt him, gently but forcefully. After all, love is pain, isn't it?
Tiasite got a respectable job at Café Poirot, downstairs from Ran Mouri's home. For the first time in his life, the hand that held a knife served a cake to Ran.
The 1.9-meter-tall, red-haired, green-eyed big dog leaned against the café entrance. "Miss Mouri, if I pay you, would you be interested in being my owner?"
Ran Mouri: Don't come any closer!
Amuro Tooru: What do I do when my coworker keeps going nuts? Asking online, urgent.
P.S. This breaks up Shinichi and Ran, but doesn't bash Ai or Conan.
The male lead is an utterly deranged love-brained simp with twisted values.
A work by the author of Detective Conan: Black Iron Submarine, written after the movie broke their heart.
Theme: Love means walking side by side.
