Takaaki is one of the yandere characters for the listener in Yandere Heaven volume 2.
Background[]
Takaaki has worked at the Makoto High School Affiliated Hospital for a long time. Although he is a psychiatrist, Takaaki was a surgeon for a period. He also took up a course of cosmetic surgery, but his reason for it is never specified. For the last few years, he was in charge of taking care of Sakae, an arrogant and rich patient. Prior to the main story, Takaaki is placed in charge of the listener for the duration of her internship at the hosp.
Yandere Traits[]
Takaaki is incredibly kind and patient towards the listener. He's willing to let her take a break if she is tired and inform her about all of her duties. Despite knowing her for a few days, Takaaki becomes attached to her and tries to keep Sakae away from her. He frequently pops into Sakae's room to take her away from Sakae. He regularly makes threats against Sakae just to get him to back off his pursuit of the listener. His threats escalate in his ending when he threatens to use an illegal substance to sedate Sakae for refusing to let him talk to the listener. He offers his help as much as possible, especially when Sakae is involved. He steadily becomes more fixated on her and is willing to do whatever it takes to protect her, including getting rid of Sakae. He becomes quite protective of the listener so much so that he contemplates using extreme means of getting rid of his rival to ensure her safety. He takes advantage of Sakae's listening devices and all the knowledge of the listener to fuel his own ambitions for the listener. Learning that Sakae got rid of the listener's boyfriend and bought out her apartment building made Takaaki happy that he and the listener could be together and have no one interfere with their new life together.
