Kunihiko Maeda is a character from the game Parasite Eve.
He is a Japanese scientist that shows interest in the science of Mitochondria and the original Eve. He is a 35-year graduate that is knowledgeable on a broad range of subjects and is slightly superstitious. He develops mitochondrial bullets laced with Aya Brea's DNA that assist her in defeating the Ultimate Being. In the ending of the game, it is hinted he has feelings for Aya, but his shy and reclusive nature prevents him from saying anything. He is also referenced in the second game, more prominently in the ".44 Maeda sp" bullets for the Mongoose magnum, which is some of the most powerful ammo available for Aya.
