General
When you have eliminated the impossible, whatever remains, however improbable, must be the truth.
—Shinichi, quoting Sherlock Holmes from The Sign of the Four, ch. 6
In detective work, there's no winning or losing...there's no being superior or inferior...That's because...there is always one and only one truth.
—, talking to Heiji
One truth prevails!
—One of Shinichi's catchphrases.
"With a keen eye for details, one truth will prevails!"
The only ones who can miss a kick draw are those who have the courage to kick it.
Zero is where everything starts! Nothing would ever be born if we didn't depart from there...And nothing would ever be achieved!
—Episode 621
A trick is nothing but a puzzle mankind came up with. If you use your head, you can uncover the logical answer.
—, talking to Heiji
It's always the little things, that we overlook, that are the most important.
The strong one doesn't win. The one who wins is strong.
