Visionaries
Mekata is featured in five Visionary cutscenes in the Game Boy Advance and iOS versions of the game.
In Photo Frame, Mekata decides on giving Hiroko away to different parents as he will not be able to make any time for her as a researcher. He talks about how when his late wife fell ill, her treatment was delayed due to the reduced medical facilities that the Great Destruction caused, leading to her death. Not wanting anyone else to meet a similar fate, he switched to medical research, and then the Center started mobilizing scientists, who Mekata had no doubt were trying to accomplish something of a large magnitude. Knowing that it will take up all his time, he concludes that it would be better for Hiroko if she grew up in a family that lived in the Center. He wonders if he'll ever be able to tell Hiroko the truth some day, but tells himself that he won't as long as he lives.
In "Ebony wand", Mekata is in disbelief that he has met Hiroko again as part of the Messiah Project. Though at first, he believed that the Project would save people, Hiroko being used as the donor for the artificial insemination shakes his faith in the project massively, making him wonder if it is all God's doing that he is separated from her. As his doubts pile up, he finally decides to take action against it.
In "Cracked Flask",
In "Broken PDA", Mekata receives a call from a young Hiroko using a dormitory phone, who eagerly tells him of a story she had heard that day about the Blessed Mother and the Messiah. Mekata says he must continue working, however, disappointing Hiroko and making her ask him when he will come to see her, with him hesitantly telling her he might be able to see her the next week. She sadly asks him to promise her that he will really see her then, to which he does, and then hangs up the call, leaving Mekata to contemplate if he is a failure of a father.
In "Piece of White Coat",
