Kogoro has an overinflated sense of his importance and detective prowess to the point where he doesn't investigate why he is suddenly and consistently passing out at crime scenes and solving cases in his sleep with different deductions than he was making while awake. Kogoro is also frequently unprofessional in his work, frequently making sarcastic and blunt comments about suspects or even his clients.

2 (Angry) I have to make a living, you know!

Megure is a capable veteran officer who cares much for his underlings, but he is prone to occasional shouting fits whenever something does not go right or when his temper gets the better of him. He also has little patience for fools, but tends to be a bit too conservative, limiting his ability for flexible thinking.

0 (Neutral, Explaining) Now, Now, Sir. The victim was a guest invited to your party-- President Yamazaki of Yatsubishi Bank! Please have a little patience.

1 (Concerned, Explaining) So, temporarily taking you and Ran out of the picture, there were 5 passengers total. Passengers A and B in the first row were both friends of the victim.

2 (Serious) Alright! Take her into custody as the prime suspect!

Ayumi is a primarily naive and innocent little girl who enjoys adventure. She demonstrates courage as time goes on and acts as the group's cheerful spirit. She has an open crush on Conan, even dreaming about marrying him, which makes him uncomfortable.

0 (Neutral, Excited) That was totally fun! For a big guy, you sure get scared easy, Genta... But the Mystery Coaster should be okay for you two, right?

1 (Explaining) Now we just get in line for seats! That's what we're trying to find out!

2 (Excited) Aren't you that high school detective?!

Mitsuhiko enjoys reading science books and takes a scientific approach to problem-solving. He is a smart and well-read first-grader who believes that technology can solve most problems.

0 (Nauseous) No, it was so totally bad for the heart! Ayumi, we only have enough left for the train back home.

1 (Scared) Which way is the line?

2 (Nervous) Those are police cars! We didn't sneak in for free!

Genta is the self-proclaimed leader of the Detective Boys. He loves food, especially braised eel on rice, and can eat more than all the other Detective Boys members combined. When discussions of money come up, Genta tends to think about it in terms of how many eel bowls he could buy. His brash personality, lack of awareness of his surroundings, and tendency to not think before acting often lands the Detective Boys (or at least himself) in sticky situations.

0 (Nauseous) Let's go home...

1 (Nervous) Now what do we do?!

2 (Scared) What was that?! Let's get the heck outta here!

Of the high ranking members of the Black Organization shown, Gin is the most loyal: he follows the boss' orders most closely and virtually never acts against the Organization's greater interests. He is also one of the Black Organization's most dangerous operatives; Conan miscalculating his intelligence, abilities, and speed of response have resulted in several very close calls and awry plans. Gin is a merciless and efficient assassin. He has no compunctions about killing or threatening fellow teammates. Fitting his icy personality, Gin's displayed range of emotions so far is relatively limited. Wearing a threatening smirk, he enjoys hunting traitors, watching the plans he has concocted succeed, and cornering his targets.

0 (Serious, Irritated) So he's Kudo.

1 (Irritated) Hurry up, will you? We don't have time for your little detective games!

2 (Explaining) No. The place is crawlin' with cops. We'll use this. Our organization's latest poison. It won't even show up in autopsies. So long, Detective.

Vodka speaks and acts like a typical mafia or Yakuza type gangster, and he is just as ruthless a killer as his partner Gin. However, he is also more easy-going and trusting than the latter, thus making him more susceptible to traps Conan sets to apprehend the Organization. In addition, he tends to not perform well under stress without guidance from Gin or other characters,.

0 (Serious, Irritated) Out of way! We're first!

1 (Serious) Sorry for the wait, Company Director. I know. I rode the roller coaster and checked from above.

2 (Serious, Nervous) Isn't he that detective, boss?! Want me to take care of him?!

Takanori is pretty rich and really likes living his extravagant life and earn money. His motive for murder was probably because of financial problems with Yamazaki. He isn't subtle in disguising his stuff since he freaked out when Sonoko told him Shinichi was a detective.

0 (Serious, Irritated) Could you get serious for a moment, Inspector Megure? How long do you intend to detain all of my guests? We don't have any more time to be part of your fruitless investigation!

1 (Serious, Irritated) Nonsense! it's almost 10 meters to the next window! Jumping from one to the other is impossible!

2 (Nervous) You must be joking! My leg hasn't even healed yet!

0 (In Tears) Aiko! And I thought you and Kishida were on good terms... How could you...?

1 (Shocked, Nervous) W-What are you talking about?! The knife was in Aiko's purse!

2 (In Tears, Confessing) It was his fault, I tell you! He forsook me! That's right! Long before I met you two in college! So that's why I decided to kill him... where we had our very first date, using the necklace he gave me!

Aiko is Kishida's current girlfriend, she was about to be taken to jail for the murder of her boyfriend she didn't commit, until Shinichi Kudo proves that it was Hitomi that killed Kishida.

0 (In Tears) Why Kishida?!

1 (Shocked) No way! I've never seen that before in my life!

2 (In Tears) N-No! I didn't do it!

Reiko is Hitomi's friend

0 (Questions) Do you know him, Hitomi?

1 (Joking) Plus it'd be impolite to disturb Aiko and Kishida!

2 (Shocked, Questions) Hitomi, you were going out with Kishida?

Gin and Vodka blackmailed an unnamed company owner who had been smuggling guns for over 100 million yen in cash. After Vodka received the briefcase of cash, he returned the film evidence of the business' gun smuggling. Vodka may have intended to kill the man when the transaction was complete as he began to draw his gun, but it could also have been in response to the company owner's remark the organization does even worse things than gun smuggling.
