My Little Monster focuses on the relationship between Shizuku Mizutani, who has absolutely no interests except in studying and her plans for the future, and a boy named Haru Yoshida, who sits next to Shizuku in class but rarely attends school. After Shizuku is tasked with delivering class printouts to Haru's home, she meets Haru, who immediately greets her as a friend, starting their new relationship. Nicknamed "dry ice," Shizuku is renowned as a girl who is emotionless and cold. However, when she meets Haru she is touched by his innocence and his lack of knowledge concerning human relationships. Though known as a violent and uncontrollable monster, Haru is actually kind and gentle. Haru immediately declares his love towards Shizuku, but it takes much longer for Shizuku to realize and accept her own feelings towards Haru. Together, as two previously unsocial beings, they help each other learn how to care for each other and relate with their friends and family.


Main charactersEdit

Shizuku Mizutani (水谷 雫, Mizutani Shizuku)
Voiced by: Mariya Ise (drama CD), Haruka Tomatsu (anime)[2]
Played by: Tao Tsuchiya[3]
Shizuku is a high school girl who focuses all her time on academics so that she can have a future career with a 10 million yen annual income.Ch. 1 She is considered cold by many for her no-nonsense and blunt attitude, and has no friends, but after encountering Haru, she starts expressing more of her emotions, standing up to situations that seem wrong like when Haru had been used by his alleged friends for money. Although she is bothered by Haru and his antics, some of which are romantic gestures towards her, she develops feelings for him. She is proud of being number one in her class, but after meeting Haru, whom she thought would be her academic rival, she no longer enjoys the thrill of topping that list. Her classmate Asako Natsume calls her "Mitty" (ミッティ, Mitti) and becomes her first female friend.Vol. 1 Although she styles her hair in pigtails and dresses rather plainly, preferring wool underwear and clothing that she gets from sales from retail stores, there are occasions where she has let her hair down, although Haru prefers the tails because he would be unable to find her.Vol. 10
Throughout the story, Shizuku often questions why she is attracted to Haru and likes him so much. In the manga, she admits to Haru that she was jealous of his personality and that he will never understand her feelings. When Haru runs away, she blames herself for it. However, when he returns, he wants her to share to him her feelings. Haru tells her that he is going away for a year, so she is without him for her third year of high school. Nevertheless, she stills remains faithful to Haru and continues on with her life. She marries Haru after college, and there is a teaser at the end of the manga that shows her working at a legal agency.Vol. 13

When he meets Shizuku, the first schoolmate to ever do something for him, he immediately considers her his first real friend and does many antics to be with her, following her around at school, and pulling her away from her routine life. He tells her that he likes her and might even be in love with her, which often flusters Shizuku. He has a spontaneous and carefree personality and often takes his frustrations out physically on other people.

He cares for Shizuku deeply, and gets jealous of Yamaken's interactions with Shizuku. Later on, he and Shizuku end up in different classes for their second-year of high school, but this does not change their romantic intimacy. He shuns his father's rich and famous family background, and went to live with his aunt Kyoko (Mitchan's mother) who had been cast out of the family. It was from Kyoko that he started learning how to find someone to love. When he attends his brother Yuzan's birthday party with the socialites, he and Shizuku have a falling out and he stops attending Shizuku's school.Vol. 10 But he eventually comes back and reconciles with Shizuku.
