Ai Haibara and Mitsuhiko Tsuburaya

Mitsuhiko and Haibara hearing the radio.

Relationship analysis

Mitsuhiko develops heavy romantic feelings for Ai, and Ai is aware of this. However, although Ai is kind to him, she does not seem to reciprocate romantic feelings for Mitsuhiko, perhaps because she really much older and has had very different life experiences. Ai uses his feelings to her advantage when she needs him to do something, but she also does admire his courage during missions the Detective Boys must perform and respects his feelings. She also in some episodes showed more confidence with Mitsuhiko than with Ayumi or Genta. Ai is often irritated by the childish behavior of the Detective Boys. However, in this regard she clearly has more problems with Ayumi and Genta, because Mitsuhiko is cleverest of the three. A recurring element in the Mitsuhiko-Ai relationship is Conan; he is usually secretly observing their "moments" and poking fun at Ai's interest in Mitsuhiko while she rolls her eyes and makes some ironic comment.

Moments

Manga/Anime

Episode 212-213: Mushrooms, Bears, and the Detective Boys

This is the first episode that Mitsuhiko starts to show affection for Ai. In fact, it appears to hit rather quickly. As she is speaking to Ayumi, Genta and Agasa in one of her adult-like explanations regarding the apple being the forbidden fruit of Adam and Eve, causing them to be banished from the garden of Eden by God, as well as the apple being able to analyze good and evil, he's struck by her words and blushes. Conan notices this and asks "What's wrong? What's with the weird look?" and Mitsuhiko gets defensive at first, stating "I'm not making a weird face!" He seems to give in and answers with "I was just looking at her." Directing their attention to Ai. Mitsuhiko continues speaking about her then, saying "Haibara-san's words are harsh but she's really pleasant, smart, and mature. Don't you think she's mysterious?" Growing embarrassed Mistuhiko tries to cover up his words by stating "B-but, just because, it's not like..." Conan's face grows serious as he places a hand on either side of Mitsuhiko's shoulders, replying with "Well, Mitsuhiko, I won't say anything mean, but don't choose her. She'll be too difficult to deal with." Haibara hears him say this and blinks in confusion at the two.

Later in the episode, Genta gets lost while they are searching for a certain kind of mushroom and Ai makes Conan pair up with Ayumi and tells Mitsuhiko to come with her to go look for him. Conan gets a dark look on his face and says "Be careful, Haibara." as they are in hunting territory and humans are often mistaken for animals and shot by accident. Ai smiles in a very genuine way and says "Thank you for worrying about me." Conan scoffs and says "Whatever." Mitsuhiko feels left out and looks from one to the other repeatedly. When they start searching, Mitsuhiko remembers this and asks "What is your relationship with Conan?" when she gives him a confused look he goes on to say "You two often go off into a corner and talk about things normal children don't understand. It's like you two only understand each other...like you're in your own little world." Ai brushes him off and says "You're wrong. It's not as romantic as it seems."

In episode 213, Ai falls to the ground after twisting her ankle when they are running away from what they think at the time is someone intentionally trying to shoot them.

Mitsuhiko immediately runs to her side and cuts his towel into strips to wrap it around her ankle like a bandage. Ai is conspicuously delighted by his natural intelligence and exclaims to Mitsuhiko "Wow, that's amazing!" Mitsuhiko blushes and then looks down saying "Actually, I sprained my ankle when I was camping with Conan-kun once and...Conan-kun...he showed me this. He knows everything. He's amazing. He's also a great leader. I'm not even close to being like him..." After a pause Haibara smiles and says "Stupid...the most important thing is that you have this knowledge and can use it after learning it. Right now, you're my outstanding rescuer. Thank you for your help." She nods with a pleased expression when Mitsuhiko blushes and stammers "Ah, n-no. I'm embarrassed by the way you said that!" When he stands to continue, Mitsuhiko supports Ai and carries her from the mountain. The scene ends with her gazing at his reddened face intently.

On the ride home at the end of the episode, Haibara is sitting in the front while the rest are in the back, discussing what had happened. When Mistuhiko comments about Jubei ((The female bear)) and Matasaburo Saika being friends for 20 years, thus explaining why he was willing to kill to save her, Haibara shoots him down, stating "When an animal lovers goes this far, it's rather annoying." Visibly hurt, he sits down and talks with Ayumi, who picks up the conversation with him. When Mistuhiko is no longer looking at Haibara, she turns and watches him, letting out a small smile. Conan notices this and smirks at her smugly, causing Ai to blush and reply in anger with "What are you looking at?" He simply says "Nothing." and leaves her to look away in spite.

Episode 279-280: Hooligan's Labyrinth

The episode begins with the Detective Boys and Professor Agasa having just finished watching a soccer/football game between the Tokyo Spirits and Noir Tokyo. On the train back Mitsuhiko is listening to the sports results of the next game on the radio and Ai puts her head against his to listen. He notices how close she is and blushes, stammering "Ha...Haibara-san." Turning to face him, Ai asks "How is the game?". With a bright red face Mitsuhiko manages to say "Uh, y-yeah." and reports that the game is still zero to zero, saying that they had just got into the first half of the overtime period. Conan takes notice of the two when Haibara asks if number 9 from Big Osaka ((A player by the name of Ryusuke Higo)) is still on the field. With a nervous swallow and the blush still across his face, Mitsuhiko manages to say "Higo is still playing. But the booing makes it harder for people on his side to pass the ball to him." Haibara looks to the ground as he says this, whispering "Oh." Concerned for her, Mitsuhiko stares at Ai sadly and says "Um, Haibara-san?" Before he could speak more, Haibara glances up at him and states "Well, please let me know if anything happens." Excited by her request Mitsuhiko replies "Yes, of course!"

At the end of episode 279, Haibara leaves the group pretending to have to use the restroom. After Conan solves the murder in episode 280, and the police take him away, Genta remarks that Haibara is slow to return. Mitsuhiko and the others don't know where she is until they notice her standing on the platform on the other side of the train tracks like she's going to get on a different train. Conan fears the worst and bolts up the stairs to try to get to her before she leaves. When he's on the other side, she's no where to be found. Conan pauses to catch his breath, and screams her name. Haibara appears behind him and says "Why are you shouting?" Conan tries to save face but she already knows that he thought she had run away. She tells him, with slight irritation, that she was just searching for Mitsuhiko's portable radio that he had lost earlier in the episode.

Episode 289-290: Mitsuhiko's Mystifying Forest

This episode begins as a regular day. They're all doing community exercises outdoors to mark the beginning of summer, while Ayumi explains to Genta about how radio exercising and fireworks are some of the only symbols of summer that haven't disappeared over time. Ai suddenly states "Speaking of disappearing...Tsubaraya-kun isn't here today either.", being the first of the group to note that Mitsuhiko isn't present. It seems he has been gone for a few days already.

Later that day the Detective Boys and Agasa go to Mitsuhiko's house to check on him. His sister says that "Mit-chan" (as she calls him) was going camping after the exercises, and is surprised to hear that he wasn't with the Detective Boys already. She also mentions how excited he seemed to be. The gang begins an investigation into the whereabouts of Mitsuhiko, following his tracks, and leading them into a forest located in the mountains. Ai voices concern then by saying,"What is it that made Tsuburaya-kun, the serious and considerate one...Turn his back on us for the first time and travel this far into the mountains?" The end of episode 289 shows that Mitsuhiko is now lost in the forest.

Episode 290 begins with the Detective Boys desperately looking for Mitsuhiko in the forest, where it is now known a serial killer has escaped. During Haibara's remarks that the serial killer is an ex-Black Organization member, and how she couldn't sense him like she normally could, most likely due to living such a peaceful life now; Conan suddenly remarks with "That's good!" This surprises Ai. Conan goes on to say "That means you're finally being able to live a normal life, doesn't it?" Then he states that they shouldn't waste anymore time, and continue looking for Mitsuhiko. As Conan turns to walk away, he finishes by saying to Haibara, "After all, he's a crazy guy who wants to see you and Ayumi-chan smile." Completely surprised by this, Ai questions him, asking,"Yoshida-san and I?" Before he can reveal why Mitsuhiko was in the forest in the first place, they hear the beeping of a Detective badge in the distance. The serial killer approaches with Mitsuhiko, but lets him go and easily walks off with the police, seemingly content.

In the end it turns out that Mitsuhiko went into the mountains to find fireflies because he overheard Ai and Ayumi talking about how pretty they were, and wanted to surprise them. When he finally caught one, he couldn't answer his detective badge or it would get away. It was a symbol of summer that you couldn't find in the city. One he overheard Ayumi and Ai stating they would like to see. Mitsuhiko ended up risking his life just to impress Ai because there was a dangerous killer roaming the mountains. Ai is astonished when she learns this and says "You did all that for us?" Referring to Ayumi and her. She goes up to Mitsuhiko and quietly says "Thank you." It seems his actions honestly impressed her. The night is suddenly filled with the glowing lights of fireflies, and everyone observes, even the serial killer, who perhaps lied about a buried body in the forest to come see the fireflies one last time.

Towards the end of the episode, Ayumi mentions to Haibara about the TV broadcast sighting of a legendary animal, called Tsuchinoko. Both girls mention how they would like to see it, while Genta and Mitsuhiko listen from behind. The two boys then begin plotting ways to go find this creature to show Ayumi and Ai, leaving Conan to think to himself,"Here we go again."

While Conan tries to figure out who the culprit is, Ai holds onto him freaking out about her "sixth sense" with the members of the Black Organization. She suspects that one of the three is a Black Org. member. To get a better look at them, she asks Mitsuhiko to do her a favor. She puts her hands on is shoulders and says "Stay like that and walk backwards. That's all I need." Mitsuhiko blushes and then says "Walk backwards? Is there something behind me?" as though someone is pulling a joke on him. Ai holds his face in her hands and says "Don't turn around. You need to keep looking at me." He stammers "Y-yes." They walk backwards until Mitsuhiko says "Haibara-san, you're hurting me." because she's grabbing his shoulders too hard. She accidentally pushes him out of surprise and he falls to the concrete and scrapes his elbow. Ai is very much anxiously around Mitsuhiko when it pushes him mistakenly to ground.

Scared that the cat would freeze to death inside the car, the detective boys follow it and end up locked inside by the unknowing drivers.

Eventually Ai is left wearing nothing but her underwear and hides away from Conan and the others. When the children find out that Haibara is practically naked in the freezing car, Mitsuhiko goes over to her and offers her his jacket to prevent her from getting cold and to cover her up when they leave the car. Ai thanks him with a smile and strangely doesn't seem bothered by showing Mitsuhiko her underwear even if she got angry at Conan for looking. Conan tells them they can't leave the van yet, since he had discovered a corpse in one of the boxes. Their phones and badges don't work, so they are trapped inside the freezer.
