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 is 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 admires his courage during critical situations and respects his feelings. She, in some episodes, also shows more confidence with Mitsuhiko than with Ayumi or Genta. A recurring element in Mitsuhiko and Ai's relationship is Conan; he usually secretly observes their "moments" and pokes fun at Ai's interest in Mitsuhiko while she replies with some sarcastic comments.

Moments

Manga/Anime

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

• This is the first time that Mitsuhiko starts showing affection for Haibara. He blushes after she explains about the legend regarding apple being the forbidden fruit. When asked by Conan why he made such a strange expression, Mitsuhiko answers that he was just looking at Haibara, as he is amazed by her intelligence, mature personalities, and mysteriousness. However, the boy gets embarrassed and denies that he has feelings for her. Conan then warns him that Haibara is not the right choice for him, since "she'll be too difficult to deal with".

• Later, when the group's spreading out to search for Genta who got lost, Haibara chooses Mitsuhiko as her partner, much to his surprise. Meanwhile, Mitsuhiko is concerned about the way Haibara and Conan usually discuss in private, about things that normal children don't understand, and wonders whether there is some kind of relationship between the two. However, Haibara states with a serious look that her relationship with Conan "is not as romantic as it seems".

• When Ai falls to the ground after twisting her ankle, Mitsuhiko immediately runs to her side and aids her by cutting his towel into strips to wrap around her ankle, just like a bandage. She is conspicuously delighted by his natural intelligence and compliments him. Mitsuhiko blushes and answers modestly that he actually learned this technique from Conan. The boy then sadly comments on how smart and knowledgeable Conan is and the fact that he can't compare himself to the young detective. Unexpected to Mitsuhiko, Haibara smiles and tells him:

“	How silly... The most important thing is that you have this knowledge and know how to use it after learning. Right now, you're my most outstanding rescuer. Thank you for your help...	„

• Mitsuhiko shyly blushes because of Haibara's compliments. They stand up and continue walking, with Mitsuhiko gently supports and carries her away while smiling in happiness. It is implied that Haibara's aware of his feelings for her, as she stares at his reddened face silently.

• On the ride home at the end of the case, when Mitsuhiko is no longer looking at Haibara, she turns around and observes him, revealing a gentle smile. Conan notices this and smirks at Haibara, causing her to blush and she awkwardly asks what was he looking at.

Episode 279-280: Hooligan's Labyrinth

• On the train, when Mitsuhiko is listening to the result of the game, Haibara leans her head right next to his in order to listen to the radio. Mitsuhiko constantly blushes as she questions him about the status of the game and whether the player Ryusuke Higo is still on the field, to which he answers awkwardly. Haibara then asks him to let her know if the match starts again, and Mitsuhiko agrees with his face still red.

• At the end of the case, Haibara leaves the group and Conan suspects that she's trying to depart away from them all by taking another train. However, it turns out that she has been looking for Mitsuhiko's lost portable radio this whole time.

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.
