A scietist who resides in the pharmaceutical department at a Japanese university. He is a very competent scientist, but completely indifferent to everything else. When he is engrossed in his research, he sometimes doesn't return home for days.

For this reason, not only his clothes are untidy, but his hair is perpetually uncombed. Naturally he has no luck with women.(hmmm this character reminds me of someone again.....) It's seems that in this game I think he had a crush with Aya but He could not tell her or did'nt have the right time to tell her, poor maeda.........

After an incident that took place a number of years ago, he was devoted his studies to mitochondria.
