Watari kun’s XX is About to Collapse Plot Overview
Genre: romantic psychological drama
The story centers on Naoto Watari, a 16-year-old high school sophomore who has structured his entire life around caring for his younger sister Suzushiro after losing both parents two years ago. Living with his aunt Tamayo, Naoto has deliberately isolated himself from typical teenage experiences – avoiding dating, club activities, part-time jobs, and even friendships – all to prioritize his sister’s well-being above everything else.
Naoto’s carefully maintained routine is shattered when his childhood friend Satsuki Tatehana transfers to his school, bringing with her the painful memories of their shared past. Satsuki was once known as a “field vandal” who mysteriously destroyed a field that Naoto had been cultivating together with his family – an act that left deep emotional scars and ended their childhood friendship.
The return of Satsuki creates ripples throughout Naoto’s social circle, affecting not only his relationship with his sister but also his connections with classmates and potential romantic interests. As secrets from the past surface and new relationships form, Naoto finds himself at the center of a complex web of emotions that threatens to completely collapse the stable life he’s worked so hard to build.
The series explores themes of grief, family responsibility, forgiveness, and the difficulty of moving forward while carrying the weight of past trauma. It’s a story about how one person’s return can completely destabilize someone’s world, forcing them to confront buried feelings and make difficult choices about their future.

Main Characters and Voice Cast
Naoto Watari (CV: Shuichiro Umeda)
A 16 years old, second year high school student. He lost his parents two years ago, and is now living with his younger sister Suzushiro in his aunt Tamayo’s house. His younger sister Suzu is the center of his life above all else, and he is a bit of a sister complex. Perhaps because he dotes on his sister so much that he has not socialized with others, he is timid and insensitive when it comes to human relationships. He can also be a bit indecisive. When his parents were still alive, he lived in Shinshu, where he met Satsuki. He was close to Satsuki, and even had a slight crush on her, but since the “field vandalism” incident, he has been wary of her.
Tatehana Satsuki (CV: Yumika Yano)
A 16 years old, second year high school student. Naoto’s childhood friend. When she was young, she was raised by adoptive parents who run an inn in Shinshu. Six years ago, when she visited the farmhouse where she used to live, she met Naoto and his family, who later moved in. Since then, she often played with Naoto and Suzu, and helped Naoto cultivate the field that Naoto’s father had made in the yard. However, one day, for some reason, she destroyed the field completely. Her whereabouts were unknown after that, but recently she transferred to Naoto’s high school and they were reunited.
Ishihara Purple (CV: Yurie Ikoma)
A 16 years old, second year high school student. She is in the same class as Naoto and is also a member of the beautification committee. She and Tokui were childhood friends and went to the same junior high school. She is a beautiful girl with a great figure, and is popular with all the boys in school. Perhaps because she was popular with boys from a young age, she has female friends, but they don’t sympathize with her and she feels a bit isolated. Something that happened in junior high school made her dislike men who try to approach her forcefully. Therefore, unlike other boys, she is secretly attracted to Naoto’s kindness, who puts his sister above all else.
Makina Umezawa (CV: Megu Umezawa)
A 15 years old, first year high school student. A junior at the same junior high school that Naoto attended in Shinshu. She was the ace of the track and field team and was the top female runner in Shinshu. She entered St. Solarina Girls’ Academy on a sports recommendation. However, she was frustrated by her poor times in her first competition and fell into a slump. Now she tends to skip club activities, which is a hassle for the club captain, but she keeps it a secret from her family. She was plain in junior high school, but changed into a flashy look when she started high school. She reunited with Naoto at the family restaurant where she was working part-time.
Shigenobu Tokui (CV: Yoshiki Nakajima)
A 16 years old, second year high school student. Naoto’s friend. She and Murasaki were childhood friends and attended the same junior high school. Both of her parents were educators, and she was raised strictly, so they don’t get along well. She often helps out at her grandfather’s flower shop. She has exceptional communication skills, is popular with girls, and has many male friends. She is always calm, and looks at relationships, including her own, from a dry perspective.
Watari Suzushiro (CV: Hinaki Yano)
A fourth-grader in elementary school. Naoto’s younger sister. Everyone calls her Suzu. She relies on Naoto and is a selfish and childish younger sister who never lets go of her brother. However, she has a tendency to act like a bad younger sister because she has a bit of a bro complex and wants Naoto’s attention, but in reality she is a very reliable and mature person.
