One-Time Male Yandere List

Some characters aren't really yandere, yet there were some point in their story where they had acted like one. Maybe they're just really angry or something? Anyway, let me present to you the one-time yanderes!

Anime is red. Manga is yellow. Otome Game is blue. Drama CD is green.

Accel World
Anime

Synopsis: Haruyuki "Haru" Arita is a short, overweight boy who is frequently ridiculed by delinquents at the Umesato Junior High School. Using his Neuro Linker to escape the torment of real life, he logs onto the school's Local Network cyberspace where he always plays virtual squash alone, and his innate video game skills bring him to the attention of Kuroyukihime (literally meaning "Black Snow Princess"), the school's popular and attractive female Student Council Vice-President. 

After helping him against the delinquents, Kuroyukihime introduces Haruyuki to Brain Burst, a secret program that is able to accelerate the human cognitive process to the point at which time appears to stop. Haruyuki soon learns that Brain Burst is more than just a program, but an Augmented Reality Massively Multiplayer Online (ARMMO) Fighting Game where people fight each other in fierce duels in order to obtain Burst Points which can be spent for acceleration abilities in the real world.

He is tall, moody, and handsome, with short dark hair and sexy eyes. Unfortunately for Sakiko, he always refuses her very aggressive displays of affection. Yet she never gives up. Even when faced with a housing crisis, Sakiko goes to drastic lengths to earn money so she can stay in the area and continue her pursuit of her teacher. However Sakiko isn't very bright when it comes to making money. She actually tries to sell herself on a street corner!! But her price is too high, and no one is interested. Then she meets a guy on the street named Natsuo. He is also really cute, with long blond hair. He is interested in Sakiko, and after one really great kiss, he takes her to his apartment. Things are starting to get steamy when they are interrupted by the arrival of Natsuo's roommate. Guess who it is?
