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.[citation needed] 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.

  • This is the first time that Mitsuhiko starts showing affection for Haibara. He blushes after she explained 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.

  • It later turns out that Mitsuhiko went into the mountains to catch fireflies because he had overheard Ai and Ayumi talking about how pretty they were, and wanted to surprise the girls, as fireflies are symbols of summer that you can't find in the city.
