What This Could Mean For Blue Box

Previously stated, Kaji will portray Kazuma Matsuoka, a student in the “Blue Box” anime who has spent time studying abroad in America. Upon his return to Japan, he enrolls as a second-year student at Sakae High School and joins the Boys’ Basketball Club. The introduction of this new character may lead to complications for Taiki Inomata, the main character, and potentially Chinatsu Kano, who he has feelings for. This could set the stage for a love triangle between Taiki, Kazuma, and Chinatsu. The theme of a student returning from studying abroad is common in anime and manga, particularly in high school slice-of-life romance titles. In some cases, these characters may struggle with cultural differences or disconnection from their Japanese roots, leading to conflicts with their classmates. Actor Yuki Kaji joins an established cast for this production.
