Yuno Gasai

Yuno Gasai is deuteragonist of the Future Diary series. She is the Second in the Survival Game and she is the owner of the "Yukiteru Diary/ Diary of future love". She is obsessed with Yukiteru Amano, the main male protagonist of the story. He is her love interest. Yuno Gasai is a young teenage girl with pink eyes and long pink hair styled in pigtails, two strands of hair hanging as frontal locks featuring a pair of red bows, and the back pigtails left bare. Her most common attire consists of a blue shirt with a ribbon on her chest accompanied by a blue skirt with high socks (school uniform), but her wardrobe changes occasionally throughout the series. Yuno's personality is ambiguous. For the most part she is sweet, feminine, and sometimes shy when around Yukiteru. But, this masks her dark and sanguinary side—ruthless, cold and calculating. She has little, if any, problem with using and taking advantage of others for her goals: her and Yukiteru's survival. She will resort to cruel and usually violent methods, most of the time coming out of nowhere, that generally end in bloody deaths, of either a Diary Holder or their followers, effectively making her a Yandere. Her brutal personality mostly results from abuse inflicted by her mother and the absence of her father, which finally ended with their deaths two years prior to the Survival Game. This was the beginning of her changes, as she later became quite lonely and sorrowful. This is shown in her somewhat morbid habits of talking to her parents' dead bodies, telling them about her day and claiming she will bring by Yukiteru. She even took their heads with her when she trapped Yukiteru in a hotel, and when Aru Akise moved their bodies, she became angry and said her parents were sleeping and that he woke them up. These events also show her complex feelings about her family. Although she wanted them to feel and understand the pain she experienced because of their abuse, she essentially just feels deeply betrayed by them. She wanted them to be a happy family, but because of their neglectful behavior and their deaths, she felt like her life had no purpose. Thus, when Yukiteru told her they would get married when they grew up, he unwittingly became a pillar of support that gave her much-needed stability. Her obsession with Yukiteru grew to escalating proportions to the point that she was willing to harm those who she believed would take Yukiteru away from her, be they friends, rivals, relatives, other girls, etc. She was prepared to resort to violence if Yukiteru's mother ever opposed her (which did not happen), stating that she did not "need her tools." Furthermore, she threatened to kill Tsubaki Kasugano, and immediately panicked that Yukiteru's friends Aru Akise, Hinata Hino, Mao Nonosaka, and Ouji Kosaka would take Yukiteru away from her, forcing Yukiteru to calm her down and announce their official "relationship", much to Yuno's joy and his own despair. At one point she even kidnapped Yukiteru and held him hostage because she was so terrified that another diary user would kill him. Aru has stated that Yukiteru provides a stabilizing influence in her normally chaotic and violent life. Despite her insanity, Yuno has shown some reservedness to killing. This is shown when, after Yukiteru calls her his girlfriend, she instantly lets Hinata go when she intended to slit her throat. The fact that she did this rather than killing her anyway to ensure that there was no chance Yukiteru would fall for her suggests that she doesn't actually enjoy killing; she merely does it because she sees no other option. It is shown many times in the series just how deeply insecure Yuno truly is when she says her life would not be worth living if she could not be the center of Yukiteru's world. Her crippling fear of losing him is notably the only thing that can cause her usually disturbing composure to crack. In the third world, the Third World Yuno seemed to be very nice and calm, possibly because she still had love for her parents and there was no survival game for them to participate in. This allowed Yuno to stay mentally sane. However, as a side effect of receiving her First World self's memories, it is implied that she might still remember some of the things that occurred in the first world as she states that she feels as if something is missing.
