AI-assisted illustrations · Not official anime stills








Rion is mentioned in chapter 55 and first appears in a flashback in chapter 64, both published in 2022. The manga itself began in 2020. Her introduction belongs to Sakamoto and Nagumo’s JCC school days; this page retains that student-era portrayal.
Outspoken and bold, she is one of JCC’s notorious troublemakers, yet her ability as an assassin is exceptional. That combination gives her scenes their bite. As a reading of her presentation, the easy grin suggests confidence rather than an inability to recognize danger; it does not establish an extra power.
[Manga spoilers] Volume 13 returns to the JCC years. To avoid expulsion, Rion, Sakamoto and Nagumo undertake a special assignment with Uzuki and enter an “assassin department store.” The flashback connects their school days to the central mystery. Shueisha’s character entry also confirms that Rion dies after fighting Uzuki.
Akira Akao is Rion’s niece and comes to JCC while searching for her missing aunt. They are separate characters. Sakamoto and Nagumo are Rion’s JCC contemporaries and important links to her past. The shared surname and visual resemblance should not obscure Rion’s and Akira’s different histories.
The visual reference is the original manga: the official volume 13 cover supplies the layered turquoise hair, golden eyes and white sleeveless top. Portrait compositions emphasize the head and upper body while preserving her youthful student-era appearance. The illustrations on this page are AI-generated, unofficial fan art, not official manga panels or animation model sheets.
[Fan interpretation] Rion can be read through the effect an absent person has on others: Akira searches for her, while the older classmates’ past resurfaces around her. Her relaxed expression then contrasts with her narrative weight. This is a reading of the story, not confirmation of a hidden identity or resurrection.
